Just bought my new 2004 C230K Kompressor Sedan and noticed that at idle it almost sounds like there is an exhaust leak somewhere - kind of that 'puffy compressed air' sound escaping. I know it's a Kompressor, haha, but is the noise normal and not really an exhaust leak? Thanks. -Norm

Any 2004 C230K Kompressor owners out there? -Norm

I have a 2003 Coupe with the same motor. I have always heard a sound of the exhaust flowing along with the fuel pump. But since it is an SC'ed motor it will always sound diferent than a NA motor will. I also get the puff puff from the exhaust tip which is the same sound every Forced Induction car I have heard and driven has made..

Thanks Jamie. This helps put my mind at ease. -Norm

Anytime and I have heard this asked before on other forums so you are not the first to wonder.
