Hey,

First I want to say thanks for the help. You guys are amazing. This is my second Benz and the reason I bought another Benz is because of all the great help that I have received from this Forum.

Ok, on with the fun!!

I just picked up this 2008 E300 (Canada) and it runs very nicely but when I start it there is a crazy whining noise that turns heads. It only makes this noise when it is a cold start.

The A/C compressor is not running because I was out of A/C gas so it automatically shut off and I haven't filled it up yet and reset it.

The noise has been getting worse now that the weather is getting colder.

I would like to fix it myself before it gets too cold but if I bring it to a garage to asses the problem I need to leave it overnight so that they can cold start it.

Any suggestions would be AMAZING!!!

Thanks again all you Benz experts.
