Is the Mercedes M272 engine reliable?
Mercedes M272 Reliability Overall, the M272 is generally less reliable than an average car. It’s not all bad, but there are a few serious issues that can lead to costly repair bills or complete engine failure. Fortunately, only the early 2004-2008 M272 engines are plagued with the balance shaft failures.
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 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.
Why does the balance shaft on a Mercedes M272 wear down?
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. Over time the M272 sprocket wears down which then throws timing off.
How much does it cost to repair a Mercedes M272?
The actual repair kits are only about $400-500 in parts. Not too bad, however the labor is the real issue. This job can often run into the $2,000+ range at a repair shop. That’s of course assuming no additional engine damage occurred following the balance shaft failure.
