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.

Vehicle has check engine light on. Also developed shifting from first to drive stalling and not exceed 20 mph.
It is a defective balance shaft. My SLK280 shows the same but a shop and the dealer said Balance shaft. See MB balance shaft class action suit. Also Valve body repairs needs to have a recall .... I'm sick about the cost I have to pay because of defective parts... MB should have to fix cars 100%

Check Engine light - OBD II Code P0025
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...
