Dealer had a look at it today before doing the V86 recall. They didn't know anything about the S/C failures, I gave them the star case number and they said something to the extent of "your vin didn't pull anything up regarding that star case". Not sure what that means.
Got the car home today and grabbed a mirror to look at the plaque on the back of the supercharger. Mine ends in AF.
The noise has not really gotten any worse, yet. My dealer doesn't seem to be fighting me, they just seem ignorant to the process. They offered to look at it with me there so I could show them the noise I am concerned about but my car only sounds noticeably bad on a cold start, so I'd have to drop it off and then show up in the morning and be there for the first crank. I'll probably pursue that option.
What happens if I get it documented that I have concerns about it, while the car is under warranty, and then it fails a year from now out of warranty? Do I eat that cost?
