Sorry if this is a repeat but I've been looking forever and cant confirm what my problem is. I've had an 04 M6 for about a year now and when i shift into first from a stop, i get a grinding noise when i'm depressing the clutch. I don't feel anything, just hear it. From what I've looked around it seems to be a throwout bearing but i'm not sure. What do y'all think? Any info would be much appreciated!
