2006 Mercedes-Benz E350 Owner Comments

Check engine light came on then went off. Took to the dealer told code was for gear in the balance shaft and that the job would be $6000. Told me it was normal wear and tear but they were willing to pay 50%. if normal wear why would they even pay. Car had 93K miles. See that this is a 2006 Mercedes E350 issue and not just wear. Need to have a recall. See there is a class action lawsuit in progress against this faulty part.

The contact owns a 2006 Mercedes Benz E350. The contact stated that the vehicle exhibited an abnormal grinding noise and was taken to an independent mechanic. The mechanic test drove the vehicle and was unable to duplicate the failure. The vehicle was taken to a second dealer where they performed a diagnostic test that concluded that the engine vacuum pump was leaking oil and needed to be replaced. The manufacturer was not made aware of the failure. No repairs were performed. The current mileage was approximately 32,000 and the failure mileage was approximately 31,000.

I own a Mercedes Benz 2006 E350 and the check engine light came on at around 54K miles. Had it check out at the dealership and they stated it was a camshaft sensor, I had them replace it at a cost of $550. Now at 57K miles the check engine light has come on with the exact same code, camshaft sensor. Upon research this is an engine/engine cooling:engine. This is a balance shaft issue common on the M272 Mercedes Benz E350 built B/T 2005-10. Cost to fix is documented @ $5,000-$8,000.

E350 6-cyl

  • 72,000 miles


Failure of the balance shaft (defective) causing loss of engine timing and engine skips and stalls. Mercedes Benz has conceded in tech bulletins to their dealer repair shops that this is a common defect for 2005-2007 E-350 and other models. The dealer repaired my car and mb paid 60% of the bill as a concession. Repair required 30 hours of labor (removal of engine, replacement of balance shaft and other parts and then reinstallation of engine). Cost was $4,000 and my out of pocket was $1,900.

problem #1

  • 45,000 miles
Check engine light occurred at 45000 miles and remains active to date. During the first occurrence the dealer performed an inspection of the vehicle, reported no issues, and advised that the light should be ignored as a false alarm. Subsequent to the initial inspection the vehicle was taken in for servicing, at which time a part (cam sensor) replacement was provided. Most recently the vehicle was taken in for epa sanctioned emissions testing at a facility in the state of Wisconsin. The vehicle failed the test. This was reported to the dealer and manufacturer; however neither are providing a cost free solution to resolve the issue. The dealer has quoted a minimum cost of $6500, and still no guarantee that it will resolve the issue. It is my position that the vehicle had a preexisting condition, and that the dealer failed to inform the nature and magnitude of the problem at the time of purchase when the vehicle was under warranty. Furthermore it has been discovered the NHTSA has released service bulletins on the mentioned issue. At this point it is unclear how an epa sanctioned requirement can be fulfilled if the dealer and manufacturer are failing to provide a remedy.
