2002 ml320 knocking at idle please help
I have a 2002 ml320 the car has a knocking noise when at idle. I do not hear it once it is reved or when driving. I like the car but need to figure this out. It has 160000 miles I had recently purchased it. It has several problems but this is my main issue I want to figure out first
