Review

Mercedes-Benz M-Class of the second generation replaced the first child in the spring of 2005. Engineers from Stuttgart have done a lot of work to create a new crossover. The car received advanced and complex technical solutions that turned into a headache for owners of the second generation ML. W164 was assembled on the assembly line of the Tuscaloosa plant, Alabama, USA. In March 2008, a restyled version of the M-Class appeared on sale.

Engines

The first serial ML of the second generation was equipped with a gasoline V6 - M272 displacement of 3.5 liters with a capacity of 272 hp (ML350), V8 - M113 5.0 l / 308 hp (ML500) and a diesel V6 OM642: 3.0 l recoil 190 hp (ML280 CDI) and 224 hp (ML320 CDI). In 2006, the line of diesel engines was diluted by the V8 OM629 with a working volume of 4.0 liters 306 liters. with. And in June 2007, the flagship V8 M113 was replaced by the M273 with a capacity of 388 hp (ML500 and ML550). In 2009, there was a marketing castling: the ML320 CDI model was removed from sale, and instead of it, the ML300 CDI (190 and 204 hp) and the ML350 CDI (224 hp) with the former 3-liter V6 OM642 appeared. The most common gasoline modifications ML350. The first M272 power units were found to have significant design flaws, which were corrected in late 2007. So, when running more than 80-100 thousand km could appear "diesel", and later caught fire "Check Engine". Reason: wear of the asterisks of the balance shaft. To replace it is necessary to remove the engine, which is why repairs are significantly more expensive. In the additives, it is necessary to change the chain of the timing system drive, the tensioner with sedatives and the magnets of camshafts, since the chain is often stretched to 100-150 thousand km, and the magnets of the mechanism of adjusting the position of camshafts begin to “wonder”. Experts recommend changing the oil pump, although there are no problems with it. For repairs in the official service will ask about 150-160 thousand rubles, along with spare parts. Independent selection of spare parts and replacement in the usual service will cost less almost 2 times - about 80-100 thousand rubles.

Transmission

All Mercedes ML engines were paired with an automatic transmission 7G-Tronic 722.9. According to the established tradition, the “automatic” pre-restyling ML W164 also had a number of problems, some of which were solved in 2007. The electrohydraulic control unit often “passed away” after 100,000 km. For the new block will have to pay about 60-100 thousand rubles. Problems with the hydroblock in some cases were caused by the failure of 2 sensors of the number of revolutions. Some services restored the hydroblock by soldering these sensors. Another common problem when running more than 100,000 km is the “welding” of the bushing, and the destruction of the gears of the oil pump box, which in turn led to the appearance of bullies in the case. Less often, problems arise with the transmission control unit (25-30 thousand rubles).

Shocks at start, stop or switch – a “pain” most Mercedes ML second generation. To cure the disease helps to change the software of the control unit of the box and engine, followed by synchronization of the blocks. The cost of such a procedure is about 6-8 thousand rubles.

From time to time there are cases of failure of the front axle gearbox. The cost of its restoration is about 40 000 rubles. Less often, there is a need to replace the front driveshaft. You have to face the wear of the transfer case chain, which will prompt cod and grind when loaded. The cost of the chain is about 5-6 thousand rubles, and works on its replacement - about 2-3 thousand rubles. If the handout will make a noise, then for its bulkhead will have to pay about 40-45 thousand rubles.

Walking

The racks and bushings of the transverse stability stabilizer serve about 60-80 thousand km. In the front lower levers, the weak spot is the rear Silentblock. The replacement of the lever is provided only in the collection. The cost of the original lever is about 22-24 thousand rubles, analogue - from 2 to 8 thousand rubles. After 50-70 thousand km, the rear ball supports often begin to creak, while they themselves have no signs of wear. Attempt to drive the lubricant under the ball anther with a syringe rarely leads to success, the ball will have to be replaced. The cost of the original ballroom is about 10-16 thousand rubles, analogue - about 2-4 thousand rubles. Shock absorbers of conventional spring suspension run more than 100-150 thousand km. So many live and hub bearings: 8-10 thousand rubles plus 1.5-2 thousand rubles for replacement. AirMatic air suspension cylinders are not distinguished by durability - the resource is in the region of 80-120 thousand km. The cost of the new original air balloon in specialized services is about 60-70 thousand rubles front, and 30-40 thousand rubles rear. Analogues are cheaper: about 20 thousand rubles and 11 thousand rubles, respectively. Many over time, there are knocks in the right front of the air suspension, disappearing when the Sport mode is turned on. Often knocking does not go away even after replacing the pneumonoid. Get rid of extraneous sounds often helps banal stretching bolts of the suspension levers or nuts of fastening the shock absorber rod to the upper support of the rack. If the knocks remained, then it is all about the AirMatic suspension control unit (about 30,000 rubles). Over time, the ML steering wheel also begins to knock.

Body and salon

The body of Mercedes ML, in the best traditions of German quality, has a good paint coating and is not prone to corrosion. The chromium packet, on the contrary, can bloom in a few winters. Mirror elements and diode daylights are often prey to “car robbers.” There are cases of distortion of the trunk door due to the destruction of screws that hold the door loop. And when the swelling is done, the swelling is thundering. After 100,000 km, problems arise with the fifth door lock due to a breakdown of the mechanism or software "glitches". In winter, the key to open the trunk door often sticks. Often problems with door locks, aggravated in winter. A little to prolong the life of the castle helps preventive measures, such as lubrication of moving parts. Often, the lock lock of the door is prevented by breaking and flying rubber band, inside which the thrust of the lock goes. The cost of a new rubber band is about 1000 rubles. Another equally common cause: the destruction of the spring in the castle. There is a remake for replacing broken springs. In the end, you have to change the lock itself. Official services ask for a new castle about 15 thousand rubles and 5 thousand rubles for work. Additional problems add to the keyless access system Keyless Go. Due to the loss of tightness of the special coating on the inner side of the handle, moisture gets inside, and the electrical contacts oxidize, which leads to failures. The cost of a new pen is about 4-5 thousand rubles. Over time, the seals of the taillights lose their tightness, which contributes to the ingress of moisture in the trunk.

The Mercedes-Benz ML W164 has actually proved to be a bit more reliable than its predecessor. It is gratifying that the manufacturer tried to solve design errors in individual units and assemblies. Unfortunately, there are many problems with electricity. The cost of individual parts and works exceeds all reasonable limits.
