CLS55 AMG
CLS55 Weird Engine Noise (help & video!)
Hey All,
I wondered if you'd be able to help me shed some light on this. I've owned my CLS55AMG for the last 2 years and it's always ran faultlessly. It has however always had this weird whining/grinding noise coming from the underside of the car towards the rear of the engine.
It happens shortly after start up and goes away once revved. But comes back. It also goes away once it's really warm (or after a long run)
Other than being really annoying, it doesn't seem to affect the drive at all. It also isn't coming from a bearing. It seems to be coming from the back/underside of the engine. I also think it got worse after my last oil change, although i can't be sure.
Anybody got any experience with this?

Both taken from underneath the car (it was on the ramp in my garage)
Cheers for your help

Chris, most of us are on the FB page for Houston, I think you'll get more replies there. It is a strange noise for sure.
