Problem Description and Possible Solution
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. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

Intermittent check engine lights. Engine feels like it has a low idle miss, kind of jerks a little bit at idle in drive with brake on. Has occassionally acted as though a cylinder was entirely missing but I also had a different code at that time which could indicate a faulty coil.
after being recalled for something I had not experienced,my dealer changed out the cam solenoid ,only telling me that it was an upgrade..I experienced the problem after the retro fit was done ...taking it back today to address the hesitation and shifting problems ...it was better before the change...
