Check Engine Light Due to Faulty Camshaft Adjuster Solenoid

The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues.

Incorrect Software Calibration May Cause Fuel Pump to Remain Powered in a Collision

There is a faulty software calibration that affects several areas including shutting off the fuel supply in a collision. This could cause a fire hazard during an accident. Dealers will reprogram this software. The Mercedes-Benz recall number is 2008 070001. This recall began during August, 2008.

I have replaced the cam sensors, rear air sprongs,brakes and rotors...

It had the factory warranty until 50,000 then we bought an extended warranty which will cover it for 5 more years or until 100,000. We needed a car (not a mini van) that could seat...
