Hi Brian,

I too am new to the Mercedes family and my 95 C280 has a high piched chirp all the time. When I first got the car about a month ago, the fan started "ticking", then I had it cleaned out and it has been squealing on start up and always has a little chirp going. Need to fix it soon, before friends test my new Benz out.

I will be awaiting forum members input to see how difficult and expensive this will be.

Larry
