Bad supercharger bearing?
Hi guys,
I recently bought a C32 and I've noticed a rather loud, grinding noise when the car is at idle. The noise seems to stop when accelerating, when the supercharger engages. I've done some searches on the forums and it looks like it could be my SC bearing.
I asked the Indy shop where I bought the car and the Mercedes dealership to look at the bearing and both said it looks okay. Nonetheless, everything I've read on here points to the bearing so I figured I'd ask you guys for a third opinion.
I've posted a video on YouTube so you guys can take a listen:
YouTube - Mercedes C32, bad supercharger bearing?
Any help is appreciated.

There were some good DIY and other suggestions posted in the thread I recently started - got the same diagnosis. Honestly, I think mine sounds a bit different from yours, but hard to tell.

Ordered the part Budget Baller suggested from that same seller - arrived quickly from overseas and appears to be in order, well packaged, made in Japan.
Have an appointment at an indy shop to try to replace just the bearing.
The supercharger pulley itself is a $1500 part, so this seems like a worthwhile attempt to fix the problem.
