Hello, I'm new to this forum. Recently, I've purchased 2009 GL320 Blutec. It was all fine for a few miles and then I started hearing high pitched whistling / screeching sound from the engine. The dealer sold the car without warranty, so no point of going back to him (he is located in Another state, anyway). I showed the truck to a local mechanic. He charged $ 800 for replacing the drive belt tensioner, belt and some sort of pulleys. However, the sound still persists. Any clue ? The sound varies as per the speed ( and also while in neutral by raising the RPMs..so, its not a wind noise). Pl. help. I've already spent enough of money and cant drive properly because of this annoying noise. Thanks !

Welcome to the forum.

I think you will have better luck by posting your question in the section for the X164 GL. This sub forum is for the 2013+ (X166) GL.
