I have a 2003 c230 kompressor and when its on park and neutal it makes this weird noise like someone is pushing the gas repeatedly the car starts shaking a bit???

What is your question?

It makes a loud noise as if someone is pushing the gass peddle over and over.. But only on park and neutral and it shekes as well

What makes this problem better or worse?

When i put it on park and neutral its starts making noise

How long has your 2003 Mercedes-Benz C230 had this problem?
