Check Engine Light On Problems of Mercedes Benz E350 - part 2

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.

Check engine light illuminated followed by another light indicating check oil level at next refueling. Had vehicle immediately examined by Mercedes Benz dealer. Engine oil level okay. No codes came up for oil sensor. Car has 66,239 miles. Was told by mbz dealer that balance shaft needs replacement due to sprocket failure (coming apart); gear is worn. Needs $6,200 of repair. Called Mercedes Benz of north America who said that to date, no recalls or campaigns have been initiated for this complaint. Car has been maintained according to mbz scheduled maintenance using mbz synthetic oil and mbz parts, if and when necessary. The internet is replete with complaints of this same type from all over u. S. And canada.

The contact owns a 2006 Mercedes Benz E350. While driving the check engine warning light illuminated on the instrument control panel. The vehicle was then taken to the dealership and a technician concluded that the timing chain cam-shaft failed. The current and failure mileages were 87000.

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.
