C220 cdi 2004 every so often goes into limp mode with P0244 fault code (turbocharger wastegate solenoid ). If the car is up to temp and driven hard no problems but seems to be at lower speed and when cold this fault occurs. Any ideas?
the wastegate solenoid fault, we need more info. there is no actual solenoid on your wastegate, but a servo motor (y100/1). at a guess i would say your code is logged by an incorrect position of this servo - this cannot be linked to the egr, only either the turbo or the servo itself. this is of course guess work without your actual code and specific definition.
