Are there any problems with the Mercedes M272?
The M273 E46 and M273 E55 engines are the part of this one family. The new version of the M272 V6, which name is M276 DE35, came out in 2011. 1. Oil Leaks. Check the plastic plugs of cylinder heads; perhaps they need to be replaced. 2. Intake manifold valves issue. The engine operates unstably with that problem.
What’s the balance shaft on a Mercedes M272?
Balance Shaft and Idler Gear Sprocket – Many early production (2004-2008) M272 and 273 engines were manufactured with balance shafts or in the case of M273 engines an idler gear sprocket that would get eroded aggressively by the timing chain.
Why is my Mercedes CLS engine not working?
As the sprockets continue to wear, the engine will develop a rattle from the loose timing chain. All the while, more and more metal is being ground away from the gears. If not fixed, one of the gears may fail eventually and take the engine out (valves hitting the pistons). It is a problem that you should not ignore.
What kind of V angle does Mercedes M272 have?
The M272 uses a 90° V angle like most V8 engines. However, that results in excessive vibration. Mercedes installed a balance shaft on the M272 to help combat these vibrations. The balance shaft sprocket on early engines was made with weak materials.

What kind of car is the Mercedes CLS C219?
The C219 CLS-Class is based on the Vision CLS concept that was unveiled at the 2003 Frankfurt International Motor Show. The design combined the roof-line of a coupé onto the body of a four-door chassis leading to a fastback vehicle.

Can a balance shaft fail on a M272?
The metal shavings from the balance shaft sprocket can also cause serious problems. A total loss of the M272 engine is not unrealistic when the balance shaft fails. Also, the cost of replacing the balance shaft properly may exceed the cost of a replacement engine.
Can a M272 engine have an oil leak?
However, given the age of the M272 oil leaks can and do happen. An important area to pay attention to are the electrical plugs for cam adjuster magnets. If the oil leaks thru the electrical connecter it can make its way up to the engine harness. That then becomes an expensive repair if the wiring harness is damaged.
Are there any problems with the Mercedes M272 engine?
Fortunately, only the early 2004-2008 M272 engines are plagued with the balance shaft failures. Though unlikely, intake manifold problems can also cause serious issues. Thermostat failures may be the single most common problem on the M272. However, it’s a pretty inexpensive and simple repair.

What are the fault codes on the M272?
When parts begin failing on the M272, air-flow may be uneven or inadequate. This can cause check engine lights and fault codes. A few common fault codes are P2004, P2005, and P2006. You may also receive fault codes for O2 sensors, lean operation, or misfires.
