whining noise - HELP!
My SLK sat for about 3 weeks while I was in Europe. I got back exactly one week ago and started my baby with this strange grinding sound!? Ok... the grinding sound did not appear again and according to this forum it's kinda normal if car sits for a while...
Yesterday I noted the whining sound, most audible around 40 mph, getting pronounced both during acceleration and slowdown. It sounds like a mosquito and its location is hard to pinpoint. It's either left front of the engine or left rear of the car.
So today I popped the hood and noticed a lot of cold water condensation around this cilinder shape (with a hose running toward the upper red engine cover) part located over the left front wheel compartment!??? Is this related? Yes it did rain this morning but the rest of the engine compartment was dry!?
Please help! Is this noise pointing out to a major failiure? I can't hear it while idling or at higher speeds? Your input is very much appreciated!
