Re: Mercedes C180 K 2006 engine 271.946

Hi, a simple and quick check is if there is oil inside the control unit. remove the connector that goes to the engine and check if there is oil there. if there is, it's almost certainly coming from the vvt units' solenoid valves.Have experienced similar symptoms with this as the fault.
