In the context of the crisis in Russia, many people refuse to buy new cars because of their rise in price and shift their interests towards the used car market. Today we decided to tell you in detail about the BMW 3-series (), which was produced from 2005 to 2012.
What modification do you want to purchase? Sedan ()? Or do you want to buy a 3-series coupe (E92)? Or do you prefer the station wagon (E91)? Or maybe you want to stand out on the road and buy a 3-series convertible (E93)? The 3-series BMW in the previous body is rich in a choice of power plants. You can choose from a variety of petrol as well as diesel engines, the power of which starts from 116 hp. and ends with an 8-cylinder version of the 420 hp engines. It is known that the Bavarian brand produced, supplied and offered a large selection of 3-series cars to car markets around the world. So, you are faced with a choice, what to buy? Or is it worth buying a 3-series at all?
There is good news for car enthusiasts. justifies the BMW brand... This German car company has always made amazing cars with a sporty drive. Maneuverability, high degree of safety, excellent performance and engine power, which is used by the latter to the limit, which was laid down in it by German engineers. This car in any body and with any engine will really provide you with driving pleasure.
But, despite the obvious advantages, multiple problems were identified in many E90 models, i.e. defects and factory defects, which in the end always affect the durability of the vehicle.
For example, from May 2006 to August 2007, BMW produced 2600 units of 320Si models. You are probably wondering what is wrong with them. But initially, we want to warn everyone, in any case, do not buy the cars indicated by us, and especially the used ones that were produced in a given time range.
And the fact is that during this period of time in this model there were problems with aluminum liners in the engine. Due to a minor defect, there is a risk of destruction of the liners in the engine block. If you buy a 320Si, which was produced from 2006 to 2007, then during operation you may face a complete engine failure. So stay away from the 320Si.
Design errors
And what is characteristic, even such diesel versions as -E90 have. It is this fact that proves and shows that the widespread myth that diesel power units much better than gasoline counterparts, not entirely true. Diesel engines, due to their complex design, sometimes turn out to be less reliable than its gasoline competitors, even despite the use of more wear-resistant parts of the power unit in the diesel engine.
Here's an example. Since September 2007 bMW company started selling diesel, with a new generation of four-cylinder N47 engines. Not a big reference, the diesel engine uses a complex design, which, in the end, is recognized by experts as unreliable. So, due to the design features of the N47 motor during operation, the timing chain wears out too quickly and for enough short term, as a result of chain wear under the hood, a characteristic loud and unpleasant sound (grinding) appears. This problem is observed in all BMW 3-series (320d) that were produced from 2007 (September) to 2009 (January).
If you think this problem is easy to fix, then you are wrong. To eliminate the defect, you need to replace the shaft crankshaft bearing and install new chain guides, which cause premature chain wear. But for this you will have to partially disassemble the engine.
Attention! The cost of repairs is about 150,000 rubles (price authorized dealer). Of course, you can make repairs cheaper at unofficial technical centers or from a specialist in a garage car service, but in any case, repairs will not be cheap.

If this problem is not eliminated in time, then later, during the operation of the car, the chain may break. As a result, the engine will receive more serious damage. The repair costs in case of a chain break in any version of the 3-series will be at least 180,000-250,000 rubles (cost at a BMW station).
Please note that 2011 vehicles with N47 engine also show defects that lead to premature chain wear. Therefore, in the event of a grinding or cracking sound under the hood, immediately contact a BMW service station to diagnose engine operation. ...
Experts tested a used BMW 3-series car and identified all the weakest points in the car. Thus, if you want to know what you need to pay close attention to when buying a used BMW 3-Series, see the photo report below:
For the analysis and test, a used BMW 3-series was taken as a basis, in the back of E90 (model 320d) and with a range of 135,000 km. Year of car production: 2005 year.
The average market value of a car on the used market is 600,000 rubles. Recall that this 3-series body (fifth generation) was produced from 2005 to 2012.
During this period, the following car modifications were produced:
Four-door sedan - E90 body
Four-door station wagon - E91 body
Coupe - body E92
Two-door convertible - E93 body
Coupe, station wagon and convertible arrived in worldwide sale in August 2006.
Ignition coils
By purchasing petrol car, turn your attention to the ignition. Defective ignition coils in operation power plant there may be gaps. It is almost certain that ignition coils will not work efficiently over 120,000 km. In this case, get ready to spend about 8000-10000 rubles on them + the cost of work at a service station.
Exhaust gas recirculation valve
As in many diesel cars, the first thing to look for when diagnosing a used car is solenoid valve exhaust gas recirculation. If its cleaning is not possible, you will have to purchase a new one. The average cost of a valve for (N47 engine) in Russia is 3000-5000 rubles.
Particulate filter
Also in the BMW 320d model, a frequent problem occurs with work particulate filter, which, due to a poorly functioning exhaust gas recirculation valve, fails prematurely. If your particulate filter is clogged, you will have to buy a new one. Filter cost for 320d (N47) - 80,000 rubles. Alternatively, you can, of course, contact a specialized service, where they will cut you out of the exhaust system and adjust the operation of the car's engine without this part. But, unfortunately, you will not be able to do all these works at an authorized dealer, and besides, such upgrades with a car often cause breakdown of other components of the car. Naturally, it all depends on how professionally the particulate filter will be cut.
Turbine
Another problem frequently encountered on the BMW 320d (N47) is the lack of long life of the diesel turbine. This is especially true for cars that were produced from September 2005 to August 2007. Due to the mistakes of the designers in the design of the diesel engine, the turbocharger breaks down very quickly. Thus, based on the information provided, before buying a used used car, pay attention to this important detail, since average cost a new turbine (don't even think about buying a used one, because by paying 30,000-40,000 rubles for it, no one will give you a guarantee that a used turbine will work for a very long time) ranges from 92,000 to 100,000 rubles.
Flywheel
A two-mass flywheel can wear out enough closer to the 100,000-130,000 km range. As a rule, the given resource of a part is 100 thousand km. For this run, the above machine part is covered with cracks and various minor defects. If installed on the machine, in the event of wear on the flywheel, you will feel vibration when changing gears.
The approximate cost in Russia is 30,000-50,000 rubles.
Suspension spring
It is likely that buying a used BMW 320d for secondary market machines, it has already undergone repair of the above components. Therefore, your task, with the help of thorough diagnostics, is to find out how well the repair work was carried out and what (and where) parts were purchased for this. Remember that if the car was installed by the previous car owner non-original spare parts on a car, all this can lead to rapid wear of previously replaced components.
BMW E90 3 Series - the fifth generation of sedans was presented at the Geneva International Motor Show in March 2005, thereby replacing.
BMW E90 embodies a new line of powerful engines, dynamic and refined handling characteristics, distinctive design and innovative equipment functions. Compared to, the E90 is 49mm longer, 78mm wider, 9mm taller, and wheelbase was increased by 35 mm. Despite the increase in size, the E90 is actually lighter than its predecessor.
BMW E90 design
In the design of the body of the E90 sedan, there are two sharp lines on the hood that start from the BMW logo, as well as side lines that go out of the headlights and pass along the car. This effect, as well as the wheel arches, add a special appeal and give a sporty appearance the car.
The design of the E90 is the expression of one idea - to provide the right body for a sports sedan in its class. Wheel arches the sedan allows the installation of high-performance 16-, 17- and 18-high-performance wheels.
Aerodynamics in the E90 is 0.26. The aerodynamic concept takes into account the smallest details of the body, from the air intake to the antenna, which guarantees harmony in movement and less air resistance, and therefore fuel consumption - especially at high speeds.
BMW E90 salon
The interior of the E90 is expressed by precise craftsmanship of the upholstery, confident grip on the steering wheel and high quality chrome trim.
The interior of the vehicle houses up to thirteen high-quality speakers. Additional system The Harman Kardon Surround Sound System is precisely calibrated for the interior architecture. Two subwoofers located under the front seats are included in standard equipment.
Specifications BMW E90
Engines and model range
The E90 was powered by 4-, 6-cylinder petrol and 4-, 6-cylinder diesel engines ranging from 116 to 306 hp.
All diesel engines are equipped with a filter as standard and meet Euro 5 requirements.
BMW E90 suspension
The aluminum front axle on the E90 provides excellent driving dynamics and superior passenger comfort. Five-lever rear axle sets new standards for superior handling, stability and dynamics. Its lightweight, high-strength designs provide precise wheel guidance and increased security in move. Rear drive and judicious use of modern lightweight materials, the even distribution between the two axles gives excellent handling and outstanding maneuverability for maximum pleasure in every corner.
DSC (Dynamic Stability Control) constantly monitors the forces acting on the E90 chassis and verifies that they are within maximum limits. If the vehicle's behavior indicates that there is a risk of skidding, the system quickly and discreetly brakes individual wheels as needed. The next generation of DSC not only offers ABS and Dynamic Brake Control (DBC), but also extended functions.
The six-cylinder E90 models offer five extended DSC functions:
- braking reserve to reduce braking distance in case of emergency;
- brake drying to improve brake response on wet roads;
- when starting off on an incline without rolling back;
- damping of compensation during sequential braking, even when the brakes are hot;
- soft stop for smooth reduction of braking distance;
The precise design of the suspension architecture allows the vehicle to drive dynamically both on the highway and on the dirt road.
EfficientDynamics
It is a package of smart features that significantly reduce emissions and improve fuel consumption, while increasing productivity. Thanks to the Auto function Start Stop, Brake Energy Regeneration and many other transmission modifications.
The Start Stop function on the E90 automatically switches off the engine when not needed and switches it on again. This not only reduces fuel consumption, but also reduces exhaust gas emissions. This feature is available on all four-cylinder E90 models with a manual transmission.
Version 320d BluePerformance and 330d BluePerformance, thanks to their filters and exhaust gas recirculation systems, have no problems with Euro 5 compliance. In fact, BluePerformance is already Euro 6 compliant, which was introduced in 2014. This is made possible by the use of an oxidizing converter, a particulate filter and catalytic converter for decreasing harmful emissions... In addition to filtering microscopic solids from the stream exhaust gases, this combination provides effective control of nitrogen oxide emissions. BluePerformance is only available for models with a manual transmission.
IDrive
The new IDrive system gives you full control over all navigation functions. With the assigned buttons, the driver has access to the most important functions... The information is displayed on the control display, which is located above the center console. This allows you to simultaneously watch the road and freely receive the necessary information. This function is only available in conjunction with the Navigation System Professional.
The sedan is also equipped with a mobile communication system on the ConnectedDrive platform, which connects the driver with the outside world. Information is always at hand to provide enhanced safety, comfort and infotainment services. ConnectedDrive provides information on road traffic, send an e-mail, connect your iPhone, visit your page on social networks Facebook and Twitter, commit emergency call to the BMW call center, and with the help of Traffic Info Plus (V-Info +) receive information on the status of traffic on the roads in real time.
In April 2006, the BMW E90 won the World Car of the Year Award for its excellent balance between performance and practicality, as well as style and diplomacy. The jury was also impressed by the new diesel engines, and wheel rim options.

BMW E90 LCI
In September 2008, the E90 sedan was refreshed and these upgrades were relatively extensive.
Externally, the restyled version of the E90 received updated design front and rear bumpers, grille, hood, mirrors, front and rear optics and trunk lid.

The interior of the refreshed E90 uses higher quality materials and finishes, and some control elements have been changed. The front seats have been fitted with crash-activated head restraints.
IN engine compartment The 320d was bumped up to 184 hp and was replaced with a new 245 hp all-aluminum turbocharged variable geometry turbine.
In 2010, the 335i was fitted with an engine.
Options BMW E90
The BMW E90 sports seats with excellent lateral support, which are ideal for dynamic driving.
Active cruise control (ACC - Active Cruise Control) installed on the car sets a certain speed when driving. For example, when it approaches a vehicle ahead in the same lane, it slows down the vehicle's speed. If the vehicle in front clears the lane, the ACC returns to its previous speed without requiring driver intervention. A short press on the accelerator disables the system.
The optional Park Distance Control for the E90 Sedan makes parking easy thanks to ultrasonic sensors at the front and rear of the car. PDC warns the driver of the proximity of obstacles clearly sound signal... Obstacles can also be shown in the Control Display if an optional navigation system is installed.
Active steering (Active Steering) on \u200b\u200bthe BMW E90 3 Series gives confident handling at high speeds and easy maneuvering in hard-to-reach places parking. Active Steering is only available on the six-cylinder E90 models.
All E90 sedans with mechanical transmission equipped with a gear shift indicator (GSI - Gear shift indicator), which constantly calculates which gear is the most economical at the moment, and accordingly advises the driver when and which gear to change. When calculating, the system takes into account the driving situation and engine load. Changing gears at the right time can significantly reduce fuel consumption, not only in city traffic, but also on long journeys.
The BMW 3-series E90 is an ambiguous model. On the one hand, the Internet is full of "horror stories" about the "lunacy" of this model, the cost of its maintenance, they compare the E90 with the previous E46 - and always in favor of the latter.
On the other hand, the owners of the E90 three-wheel drive manage to drive 300 thousand km without serious problems, they admire the handling and do not know grief. Where is the truth? Let's figure it out.
The new "treshka" BMW was released in 2006, replacing with its "illogical" E90 index previous generations - E36 and E46.
- The sedan received the designation E90, the touring - E91, the coupe - E92, the convertible - E93.
The new design became shocking, and in America and Canada immediately brought the "three" to the bestsellers. The unusual look was complemented by constant handling and an interesting interior design.
Four-wheel drive, improved dynamics, reduced fuel consumption and a traditionally large selection of petrol and diesel versions are the reasons why the E90 has remained a popular option in the Belarusian used car market for many years now.
If we compare the E90 with its predecessor E46, they are similar in design, especially in terms of size and body architecture.
But the renewal of the line of motors and gearboxes, innovative steering (active rail), a variety of electronic assistants draw a clear line between the car of the "bygone" BMW era and the modern era.
And, of course, it directly affected the cost of maintaining and maintaining a more complex structure.
Body and interior
Since the E90 is a relatively old car, the hardware of this "three-ruble note" does not raise questions from the owners, and the wheel arches and the bottom are well protected from corrosion by the manufacturer.
Structurally complex bumpers and plastic aerodynamic body kit only suffer from an accident. Pre-styling BMW E90s have situations with sagging wheel arch liners.
The three-ruble sedan with the E90 index turned out to be so successful that in 2008 German experts did not dare to change its design and appearance to a large extent. We all know that, often, "the best becomes the enemy of the good." For this reason, most likely, updated version The BMW 3 Series has been changed so that at first glance there is no change to be seen, but they are still there ...
First, safety - the basis of the 3-series E90 safety concept is a robust body built using high-strength steel grades and special deformation elements to absorb the energy that occurs when the car hits an obstacle. And optimal passenger protection will be provided by six airbags, three-point inertial seat belts and head restraints on all seats.
In addition, the E90 comes standard with ISOFIX child seat mounts on rear seats... And the front seats (already in the basic configuration) are equipped with active head restraints, which significantly reduce the risk of damage to the cervical spine in a rear collision. When struck from behind, the electronic unit safety system in the shortest time allows the front part of the headrest to move up to 60 mm forward and up to 40 mm up - as a result, the distance to the head is reduced and the effectiveness of the stabilizing protective function of the headrest increases. Simply put, the 2008 BMW 3 Series model year became even more secure.
In terms of external differences between the restyled E90 and the "previous model", the following can be noted:
- At the front of the vehicle, width is emphasized. On the side, the light edge of the side sill is now higher and has acquired more expressive forms. In addition, there are two new expressive lines on the exterior mirrors, in which the interaction of convex and concave surfaces continues. By the way, the new mirrors provide an increased field of view.
- At the rear, the sporty and energetic styling is also applied. Rear bumper, the trunk lid and lights have taken on a slightly different shape. for example taillights, consisting of two parts, now acquired the typical BMW L-shape. LED stripes of side lights also add expressiveness. The extended rear track will also add dynamism.
- The new sidewalls, the contours of the rear of the body and the front of the car, thanks to the careful study of details, have become visually wider.
The interior of the updated BMW E90 is a lot like the interior of the 5-series. Among the several interior design options, the most interesting and attractive one seems to be the one trimmed with ordinary dark plastic. But the inserts "under the tree", which are designed to give the interior solidity, seem too pretentious. Interior designers say they have applied a modern concept of convex-concave surfaces, techno aesthetics and sporty elegance.
A significant design detail in the interior of the BMW 3 Series is the 8.8-inch display, which is larger than any graphical interface on other vehicles. With its high resolution, the display provides a rich display of graphics with accurate detail. The menu structure, in comparison with the previous version, makes it much easier to find the desired functions.
This huge display is part of multimedia system iDrive, as well as navigation system.
By the way, the set of the navigation system "Professional" includes a built-in 80 GB hard drive, which provides instant access to the cartographic material converted into digital format. Of course, in addition to maps, this disk can store thousands of mp3s.
And most importantly, the 2008 model year Troika, for the first time in the history of the automotive industry, can provide unlimited access to the Internet due to the ConnectedDrive system. Only now, you can use it only in a stationary car. Data transmission is carried out using EDGE (Enhanced Data Rates for GSM Evolution) technology, which, unlike UMTS, covers large areas and works three times faster than the GPRS mobile communication standard.
Of course the Internet is important in the modern world, but other characteristics are considered the most important for a car, the most important of which is the engine. In the case of the BMW 3-series, the most interesting is the new 6-cylinder 330d diesel, which, of course, works in accordance with the EfficientDynamics concept. By the way, in terms of dynamics, this three-liter all-aluminum engine is not much inferior to the most powerful gasoline engines... See for yourself: maximum power at 245 hp the new diesel engine develops at 4000 rpm. And the maximum torque of 520 Nm is achieved already at 1750-3000 min-1; acceleration to 100 km / h occurs in just 6.1 seconds, and maximum speed electronically limited to 250 km / h.
You might think that paying for such dynamics will have incredible fuel consumption? - not at all. The average consumption of diesel fuel is 5.7 liters per 100 kilometers. Of course, if you drive dynamically, the consumption will exceed this value. But, in any case, the result achieved by BMW is outstanding.
The undercarriage of the redesigned E90 is still one of the most sophisticated. IN rear suspension It adopts a five-link design adapted to the requirements of high power and torque motors. At the rear, a double-pivot suspension is used with traction braces on shock absorbers with a stabilizer lateral stabilitymade mainly of aluminum. Electromechanical steering comes standard with integrated Servotronic, which adjusts the power steering efficiency according to speed. As an option, active steering is available, which adapts the steering ratio to the current speed.
Prices. In 2008 year BMW 3-series in the minimum configuration will cost ~ 978,000 rubles. The cost of the E90 with the most powerful engine and with four-wheel drive will amount to ~ 1,875,000 rubles.
E90 BMW is a car that is a representative of the third series of a well-known Bavarian manufacturer. It is quite extensive, and its history began several decades ago. However, I would like to consider some models in more detail.
Updated family
Exactly 15 years ago, in 2000, the third series, which had already become popular, was replenished with new models - the BMW 325 E90 and 320. These cars immediately attracted the attention of the fans of the Bavarian manufacturer. The machines received significant updates: first, the engines were improved. The power of the 325th (its predecessor was called the 323rd) increased by 22 hp. with., and now this figure is 192 horsepower... The volume, however, remained unchanged. The 320 has both increased capacity and volume. From 150 HP from. the indicator jumped to 170 liters. with., and the engine became not 2-liter, but 2.2 liters. Of external changes - larger air intake, redesigned air vents and stylish front bumper. All in all, these were two presentable cars with good technical characteristics.
About performance
It deserves to be told in more detail about its performance. For example, you can take the i330 model. So, which the “German” can develop is 250 km / h. It accelerates to one hundred kilometers in a little more than 6 seconds. small - on the highway 6.4 liters, and in the city - 12.7. IN mixed cycle this figure is 8.7 liters per 100 kilometers. By the way, the volume of the gasoline tank is 60 liters. Engine power is 258 horsepower, and the number of revolutions is 6600 with a torque of 300/250 Nm. Finally, a few words about bMW dimensions E90. Its curb weight is more than 1.5 tons, and the permissible, that is, full, is almost 2.
Sedan modifications
As you know, some of the most bought cars are those that are made in the sedan body. There were so many modifications of the BMW E90 corresponding to this category in only three years (from 2005 to 2008) that everyone can choose what suits him. The weakest model of several dozen released is 122 horsepower with a 1.6-liter engine. The most powerful option is the 335xi - a really nice car with a 3.0-liter, 306 horsepower engine.
By the way, there are options with both automatic and manual transmissions. The following models can be attributed to the golden mean - 330xd (231 hp), 325xi (218 hp), 320d (177 hp), etc. In general, the manufacturer released a lot of modifications, and this is good - there will be no problems with the choice.
I would like to talk in more detail about the appearance of the car. The design is quite distinctive and bright - a beautiful “look” of the originally designed xennon headlights, a powerful front bumper, a branded radiator grill ... Everything is in the corporate traditions of a famous manufacturer, such a “Bavarian” in the stream of other cars can be seen from afar.
What you need to know
Before purchasing an E90 BMW, you should talk about its other features besides those that you need to know about the engine. First, the braking system - both front and rear brakes - are disc brakes. Only the front ones are also ventilated. The steering type here is a pinion-rack. By the way, there is a power steering - this addition makes the driving process comfortable.
E90 BMW is a rear-wheel drive car with a six-speed gearbox (it doesn't matter which version we are talking about - both the mechanics and the automatic machine correspond to these indicators). Driving such a car is a pleasure. First, it is reliable. Secondly, trips on an all-wheel drive BMW are always comfortable, at any time of the year. The car also looks attractive - an important nuance. And the interior, by the way, is also impressive - everything inside is made in the same style, and only high-quality expensive materials were used for decoration. After all, BMW is a reputable concern, and its cars are bought by people who have good taste. So, we can say that everything is in the best traditions.
Important additions
E90 BMW - a car with a fairly diverse basic configuration... In addition to everything that was listed above, it has a lot of different add-ons. The third series is generally equipped with a variety of devices. For example, short main gear mechanics, or multifunctional that fits perfectly in the hand. Stylish emergency stop signs, electric windows, on-board computer, climate control - it's all in this car. Even such little things as a smoker's kit, loudspeaker system are provided. In general, the package bundle is impressive.
There is no limit to perfection
This is exactly what motorists think, in whose life the word “tuning” occupies a special place. BMW E90 has repeatedly succumbed to various experiments carried out by people who own this car. In fact, there are many different add-ons with which you can transform and improve your “ iron horse”. Wind deflectors, carbon pads, discs, push buttons, emblems, plugs, LED lights, front pillars stretch - all this and much more will help make the car more attractive and powerful. Of course, tuning, designed to improve the appearance of the car, is easier to do with your own hands than one that is aimed at increasing power, etc. If you need to improve the engine or something like that, it is better to turn to professionals.
Improved version
It is worth saying a few words about such a model as BMW E90 - m-tech restyling. This is a 2010 car with a 2.5-liter engine. The pre-styling version of this model had one big disadvantage - she required too much oil. But due to the fact that the manufacturer spent quite a lot of time on eliminating various kinds of shortcomings, this minus is gone. The 2010 version does not need a lot of oil - and this is one of its main advantages. The car is good, with excellent acoustic system and m-perfomance exhaust. And the car looks decent - it will excellent option for a person who needs a presentable vehicle. Such an E90 BMW would be fine without tuning.
I would like to emphasize the high level of security. It was possible to achieve excellent performance due to the zones of directional deformation and the use of pyrotechnic tensioners, as well as special safety belt clips. But that's not all. There are also airbags in the car - both for the driver and passengers.
Troubleshooting
Well, the car, of course, is not bad, but nothing lasts forever. And therefore, the question concerning such a topic as the repair of the BMW E90 is relevant. Anything can happen - starting from such a relatively insignificant moment as the need for a replacement air filter, ending with fuses, pins or even engine repairs.
It is quite possible to do something on your own, others - not everyone can do. For example, replacing the clutch disc. Quite a time-consuming and complicated process, since you will need to dismantle cardan shaft, the angle of the clutch and directly the gearbox. In addition, you have to determine the condition of the clutch cup, and this cannot be done without disassembling. Therefore, if you are not sure that this will be done, or, even more so, there is no experience, you should contact the service center.
