Mercedes-Benz GLK has been produced since 2008 in Germany, more than 700,000 such cars were created during this time. About 30,000 cars of this model were sent to Russia.

The body is perfectly protected from corrosion, despite the fact that the body shape of this car is square and attracts stones from the road. The whole front of these cars exceeds. The windshield after a couple of years of active operation becomes very shabby and worn. New original windshield costs 400 euros, but you can take 250 analogue of European production.

The paintwork is really durable, high-quality metal and electroplating protection, so if corrosion appears on the body, then this is a sign of incorrect and poor-quality garage repair. But with decorative elements on the body of things, it's not so good: on aluminum rails, white spots appear on aluminum rails, the window strips and door handles are seated after about 5 years of operation, the chrome does not look so presented on the grid of the radiator, and on the exhaust pipes Systems are also visible small traces of rust.

Salon

The GLK interior is very similar to the C-class interior in the Body W204. In the cabin, too, have its drawbacks. It happens that a signal appears that airbags are faulty, contacts in the front seats are to blame. If you adjust the chair sharply forward, and then sharply back, then the contact can be broken in the wiring. This happened quite often that the dealers warranty changed the connectors. In the car there is a passenger retention system that combines pretensioners of belts and airbags. Sometimes there were cases that this system was triggered by itself, because the system control unit gave failures. On this occasion, it was even a revocable company for cars released until 2009.

In Mercedes, the GLK, released to restyling in 2012, it is desirable that there is an armchair finish with a cloth, because the eco-ekthek, which walked in the basic equipment after a fairly short time it begins to break out, and with severe frosts after 3 years of operation can crack. In addition, the passenger's presence sensor can fail to change it, you will have to install a new seat pillow, it costs 300 euros.

In the cabin, the symptops were not found, but the inner handles will fasten almost all cars.Sometimes in the winter there are failures in the mechanisms of the door of the trunk and the electric drive mirrors, if they are not changing them, it will be very expensive. Rear ParkTronics Sensors are also often buggy. Sometimes it happens that on cars released before 2010 there were problems with the washing system of glasses - the tank flowed, as well as the electrical heating of the fluid failed. The new tank costs 60 dollars.

Motors

Gasoline motors, in general, reliable can easily serve 400,000 km., And diesel motors are even more durable. But you need to follow them all the same and correctly serve. The most popular is the diesel 2,1-liter Motor 651, it is installed at about half of all GLK. This motor is reliable, it is also installed on the Mercedes Sprinter vans. The design of the motor is simple, the cylinder block is made of cast iron, and the head of the block is alloy. Power - 143 liters. p., A single turbocharger is used in the motor.

But there was a period when Piezoelectric nozzles from Delphi were used in the motor, they also spoiled a motor reputation. Because of them, the car could lose power while driving and could stumble, passed into emergency mode. This problem was massive, so in 2011 on cars 220 CDI and 250 CDI, the engine design was finalized and instead of piezoelectric nozzles put electromagnetic nozzles, each of which costs 400 euros.

For cars that were released until 2011, the manufacturer arranged a service campaign in which the fuel system was improved, changed the firmware of the electronic motor control unit. You can also make such a procedure as prophylaxis so that nozzles are not covered in their places.

After all these modernization, the nozzles stopped straining the owners of these cars. Just every 120,000 km sufficiently. Written everything in order with the water pump, whether it flows. And on run 150,000, it is necessary to start listening, whether the timing chain was stretched. The new original chain costs 300 euros, analogue can be taken for 200. But it is not so simple to change the chain, because it is located in the back of the motor. But in most cases, the first thing is not the chain, but its tensioner or the calm. Tightening with repair is not worth it and when foreign knocks are found, it is better to immediately change the chain and related details.

And when the car has a mileage exceeded 200,000 km., It is advisable to clean the peasant filter, because if it is scored, the collector will start overheating and collapse, and its debris can damage the turbine blades. The same situation may concern and more rare 3 liter diesel engine OM 642. There are cases that the motor goes into emergency mode, in which turns do not exceed 3000 rpm, it means a lot of oil in the turbine. And otherwise, if you follow the motor, and not allow the diesel filter to be clogged, it will last long.

On both diesel engines you need to follow, so that the EGR valve is not clogged, which costs 160 euros. And after 180,000 km. It can start climbing an actuator for changing the length of the intake manifold. On cars released until 2010 there were unreliable gaskets in the oil radiator, then these gaskets were replaced with more heat-resistant.

As for gasoline engines, they can also appear to flow a heat exchanger, and the worn flaps of the intake manifold begin to be peeling after 120,000 km. Run. The new collector assembly costs more than 1000 euros. This concerns the gasoline engines of the M 272 series with a volume of 3 and 3.5 liters. There are also cases that 80,000 km. Plastic plugs of the cylinder head blocks can be progress, and the sprockets of the phase masters may require a replacement. They are not cheap - 500 euros.

Buying a car needs to carefully listen not to anything flies in the back of the engine, it is also necessary to learn from the owner whether the motor was repaired. The fact is that on GLK, which were produced in the early years, there was a problem with the drive of the balancing shaft. Already 100,000 km. The teeth could be very much to wear out that even the gas distribution phases were shifted. Because of this, diesel noise appears in the motor, and the power decreases. To change the asterisk and the shaft will have to shoot and disassemble the motor, and it is not easy. In the younger machines, modernized motors have already become installed, but they are not insured against such a problem after 200,000 km. But before that run with a motor chain everything will be fine.

The M272 series gasoline engines are quite reliable, they use an aluminum cylinder block, in the coloration of cylinders - a balance shaft, a system of ¬ changing the phases of gas distribution on camshafts. These motors have become more reliable after 2008, because a lot of things changed in the design. It should also be understood that M272 motors love only high-quality oil, fuel and timely replacement of filters. So that the walls of the cylinders were more durable, alusyl is used in these motors. In Europe, this coating does not cause any problems, because there is high-quality fuel. But this coating will suffer greatly if sandbanks or soot fall there.

After restyling, the GLK began to install more complex 3.5-liter M276 series and 2-liter turbocharged M274 turbocharged motors. These motors work on gasoline, with direct injection, which is characterized by such problems as a failure of the TNVD, piezoquormoons, still appear on the inlet valves. On the M274 motor, the turbocharger was often changed under warranty, the timing was repaired: changed chains and camshaft clutches. And if during the launch of the motor, knocks and crackles are heard, the hydraulicers that cost about 100 euros are to blame.

In Russia, it is difficult to find the most reliable package of GLK 200 CDI and 220 CDI, in which a diesel engine is installed, there is a rear-wheel drive, a 6-speed manual box. But there are cases that such cars are driven from Europe.

All-wheel drive transmissions 4matic in the GLK are the same as in other models of Mercedes Mark. Cardan shafts serve long, torque is distributed in the ratio of 45:55, there is more torque on the rear axle. On the oldest cars there was a not enough reliable distribution box, after 80,000 km. Could break the chain in it. But then this situation was corrected and the rattling began to serve without problems up to 200,000 km. Then the seals at the front cardan shank are already starting. When bearings are greatly extended on the shafts and hums and vibrations will appear during turns, it means that it's time to make repairs, if you do not do it, then the transfer box will come to an end.

There is another transmission that appeared in 2004 - 7G-TRONIC, it is pretty good for the mechanical part. The advantages of this box are that there is a high-speed 7th transmission, as well as a special control of the blocking of the friction converter friction converter, this allowed the climbers to slip at low speed even on the 1st transmission. The box turned out to be shriveling, but the reliability leaves much to be desired. If you often ride around urban reasons, friction rates will be faster and wear products will quickly pollute the oil in the box. Therefore, after about 80,000 km. In the older cars, the hydrotransformer faced.

The box was improved several times and on cars issued in 2010 - 2011, the hydrotransformer has already become 2 times longer. Adjusted boxes appear no earlier than 150,000 km. In general, the gearbox serve longer, you just need to not forget to change the oil in it every 50,000 km., Then everything will be fine.

If on a car released to restyling suddenly the box itself switches from the mode "Drive" to "Parking", then this does not mean that the problem is in the box, there may be a reason in the EZS ignition lock, which stops seeing the key. Very often, this lock of the ignition was changed under warranty, and it is not suiced - 530 euros.

But after 2012 an upgraded 7G-Tronic Plus (Nag2-Fe +) appeared. It can be distinguished by the presence of the ECO button on the console, the start-stop system also appeared. According to the regulations, it must be changed in it every 125,000 km. This box has an additional oil pump, also here is another range of gear ratios, a stronger torque converter is used, the operating pressure is less in the box, because more liquid oil is used.

Suspension

In general, the suspension in GLK is strong enough, but still there are some nuances, especially on dorestayling cars. Cars issued until 2010 were withdrawn, because they could have the depressurization of the power of the steering wheel, as there is a weak hose in the system. As for the most rush mechanism, it begins to flow after 160,000 km. In the postnestyling cars, such a problem was already solved, because they do not have a hydraulic powerful, and there is an electric powerlier, but when the knocks appear in the rail, of course, it will not be soon, then the repair will cost more.

Initially, a lot of trouble delivered front shock absorbers, which are quite a big money - about 350 euros. The thing is that it is not simple shock absorbers, there are a passive system for changing the resistance of Agility Control, for warranty, these shock absorbers changed after 50,000 km. But you can not break your head and put the usual similar shock absorbers for 100 euros. You can also put improved branded shock absorbers, which serve about 100,000 km., Rear can even serve for 200,000 km., But they cost more - about 200 euros.

Mercedes GLK Class - a series of compact crossover concern Mercedes Benz. Let's produce from 2008 to 2015. In the 12th year, a serious rastering was held, and in the 15th it was replaced by a new Mercedes GLC model.

GLK base maintenance is carried out every 15t.km (gasoline engine) / 10. (diesel engine) or 1 time per year, depending on what comes before.

The basic service of GLK includes replacement of engine oil with an oil filter, as well as replacing air and cabin filters + comprehensive check of the car condition. But plus to this, with each GLK maintenance you need to request the service code of the Assyst Plus system in the car. After decrypting in the specialized software of Mercedes Benz, you can understand the necessary list of additional works - the side of the Mercedes GLK, on \u200b\u200bthe basis of the control algorithms embedded in it, itself knows which car system needs to be paid at the next GLK maintenance - whether it is replacing the brake fluid or antifreeze. Oil automatic transmission and much more.

Mercedes GLK - is a modern and technically complex car, pay attention to GLK service should be started directly from the first then. Then this wonderful crossover will delight you with trouble-free operation for many years and will decently save the budget for breakdowns.

Mercedes GLK is the smallest crossover of the company "Mercedes-Benz", which, to all, has an atypical appearance for this brand. Most skeptics found it too square outside and rustic inside, however, it did not affect the popularity of the car and sales volumes. Despite its small age, cars of this brand are increasingly found in the secondary market, this fact makes it very much to doubt the reliability and practicality of Mercedes GLK. But what exactly forces owners to part so quickly with his car, and, what surprises can present a used "GLK", now and try to figure it out.

A bit of history:

The concept of Mercedes GLK was first presented to review the public at the beginning of 2008 at the Detroit Auto Show. The debut of the serial model took place on the Beijing Motor Show in April of the same year, externally, the car practically did not differ from the concept. According to the type of body, Mercedes GLK is a crossover, a guide for the creation of which was the wagon of the C-class "Mercedes-Benz S204". When developing the appearance of the novelty, a model "", which has been produced since 2006, was taken as the basis. The technical filling is borrowed in C-class, for example, a system of full drive 4 Matic without a blocking differential, an alternative to which is a model with rear-wheel drive. This model is offered in two modifications, one of which is designed for off-road lovers: in this case, the car has an increased road lumen, 17 inches wheels and a special package of options. In 2012, a restyling version of the car was presented at the New York Auto Show. The novelty received the stooded appearance and interior, as well as upgraded motors.

Weak places Mercedes GLK with mileage

Mercedes GLK is completed with the following power units - gasoline 2.0 (184, 211 hp), 3.0 (231 hp), 3.5 (272, 306 hp); Diesel 2.1 (143, 170 and 204 hp), 3.0 (224, 265 hp). As the operating experience showed, the most unsuccessful engine in terms of reliability turned out to be the basic power unit with a volume of 2.0. So, in particular, on cars, even with a slight mileage, many owners began to bother knocking out of the hood during the start of the cold engine. The cause of this knock is the defective camshaft, more precisely, it is not quite the right location. Therefore, before purchase, be sure to specify whether the warranty problem has been eliminated. Also, the cause of an extraneous noise when starting the engine can be a stretched timing chain.

One of the most common disadvantages of 3.0 gasoline engines is the burning of the intake manifold dampers. The complexity of this problem is that the dampers are an integral part of the intake manifold, and, separately, you cannot buy them, therefore, the collector has to be changed entirely. Signals about the presence of this problem will serve: floating turnover, weak dynamic engine indicators. If the dampers began to be littered, it will be necessary to urgently turn into a service, otherwise, over time, they will tear off and fall into the engine, which will lead to expensive repair. Also, after 100,000 km, the timing chain is stretched, and intermediate gears of the balancing shaft are wearing.

Motor 3.5, perhaps, one of the most reliable among gasoline engines, but, due to the high transport tax, this power unit is not very popular among motorists. One of the disadvantages of this unit is the briefness of the chain tensioner and gas distribution stars, their resource, on average, is 80-100 km. The signal about the need for urgent replacement will serve as a diesel rocity and metal ringing when the cold engine is started.

Diesel motors Mercedes GLK are quite reliable and extremely rarely present unpleasant surprises to their owners, especially on cars of the first years of release, but only subject to the use of high-quality fuel and lubricants. If the previous owner filled the car by a poor-quality soloar, then, already in a short time, you need to be ready to change fuel injectors and the TNVD. Due to the accumulation of the Nagar, the exhaust manifold damper can fail. Also, some owners mark the engine electronically control. On cars with a mileage of over 100,000 km, problems with pump (flow, backlash or even whistle during operation) are possible. On the engine 3.0, with a mileage of more than 150000 km, you can encounter the destruction of the exhaust manifold and the subsequent destruction of the turbine.

Transmission

The Mercedes GLK was supplied to the CIS market with a six-and seven-step automatic transmission (Jetronic). Most of these cars in the secondary market are offered with a full drive, but rear-wheel drive cars are also found. The reliability of the transmission directly depends on the power of the installed motor and driving manners, and the higher the power of the motor, the smaller the operation of the gearbox. It is very important before purchasing inspection of the box, disassemble and gearbox for oil leakage. If during slow acceleration, or during a slowdown, you will feel that the automatic transmission is even pushing a little, then it is better to refuse to buy from the purchase of this instance. Most often, the cause of such behavior is the failed electronic board of the automatic transmission block. Also, it can occur due to wear of the hydroblock and the torque converter.

With careful operation, the box, on average, will serve 200-250 thousand km. In order to extend the lines of the transmission service of the servicemen, recommend changing the oil in a box every 60-80 thousand km. The system of the full drive cannot be called very tender, but nevertheless, it is not necessary to forget that this is a crossover, and not a full-fledged SUV and, for serious loads - it is not designed. One of the common shortcomings of transmission with a full-wheel drive "4 MATIC" is the suspended bearing of the drive shaft, which is located in the engine crankcase. During operation, a dirt that provokes the formation of corrosion falls on the bearing from under the wheels. As a result, the bearing clinite and turns. To avoid serious consequences, many mechanics recommend changing the bearing along with oil.

Reliability of Mercedes GLK suspension with mileage

This model is equipped with a fully independent suspension: MacPherson in front and mono-shock. Mercedes-Benz has always been famous for a well-tuned suspension and, GLK is no exception, the car has excellent performance. Unfortunately, the suspension of this car is called the "unhappy" language, since the running, as for the crossover, is very gentle and does not like movements on broken roads. And, if the previous owner loved to knead the dirt, the overhaul of the chassis will not wait long for a long time.

Traditionally, for modern cars, it is most often necessary to replace the racks of stabilizers, somewhere at 30-40 thousand km. Not much longer live and watch the leverage, on average, 50-60 thousand km. The resource of shock absorbers, levers, ball supports, hub and support bearings does not exceed 100,000 km. The service life of the brake system directly depends on the driving manner, on average, the front brake pads have to be changed once in 35-45 thousand km, the rear - 40-50 thousand km. Before resting the car, the car was equipped with a power steering, after - electric, as the operating experience showed, most often, the owners of the rail with a hydromechanical steering amplifier (wear of the rail sleeve, fluid leakage of the GUR).

Salon

As it should be Mercedes-Benz cars, most of the separation materials of the Mercedes Glk salon are quite good quality. But, despite this, on many copies, the leather seats skin trimmed quickly and crashed, good, the manufacturer changed everything under warranty. The cabin heater motor is located before the filter, which, as a result, leads to rapid pollution and premature failure. A signal of the need to change the motor will serve as an unpleasant whistle during the operation of the ventilation system. Frequently often the owners are numbered on the refusal of the rear and side sensors of parking sensors. Also, there are comments on the reliability of the electric drive of the trunk doors.

Outcome:

One of the main advantages of Mercedes GLK is that, often, the girls own this car, and they, as you know, are more accurate on the road and scrupulines relate to car care and maintenance. As a rule, the owners of this car brand provided by the secured people, which means that the car was served only in good service, therefore, on the secondary market, cars very often come across perfect condition, just need to look good enough. To avoid serious problems and expensive repairs, try to avoid machines with the most powerful engines.

If you are the owner of this car model, please describe the problems that you have to face during the operation of the car. Perhaps it is your feedback that will help readers of our site when choosing a car.
