Hello all, A week into ownership of my S204 C320 CDI i have run into problems with the EML light on, and the car reverting to limp mode. Car was attended by breakdown organisation this morning, and Error Code P2015 identified, which appears to point towards Intake Manifold Runner Position Sensor. He removed the engine cover and checked the manifold connections. At this point the EML Light went out , and the car was no longer in limp mode. However performance was/is still sluggish and i also noticed that the exhaust tips were now quite black with carbon deposits. Doing some research on here, points towards inlet port shut off motor / intake motor failure. any comments/observations are of course welcome with any recommendations as to who/where can get this rectified for me reasonably in the Beds/Herts/Bucks region. many thanks in advance.
