A180 cdi w169
Engine idle rumble
Hello, i have a Mercedes A 180 cdi w169 automatic transmission from 2006 and everything is fine until l engine gets to 80 degrees celsius. as it heats to 80, only on idle the engine rumbles very badly, the rpm varies a little and also seems a voltage as light inside dimms. If a accelarate the car goes fine, has power and shifts ok. What might it be, i am warried.
