I have a 89 535i . It recently bit the dust I believe. You all know the "ooo sh**T that sounds expensive sound. I have been getting this grinding noise while depressing the clutch for a week or so. It felt like the clutch was engaging less and less untill finally when I depressed the clutch I couldn't get it into gear. Unfortunately I couldn't move as I was in the middle of the intersection so I force it into gear and it popped it in. The result was something to the effect of loose metal sound in the tranny or clutch area. Not sure what I did but it sounds expensive. I limped into a fix it place I trusted and they felt so bad they didn't charge me for the inspection....(which consisted of ...we don't know untill we drop the tranny...and look at the clutch)
Any advice on what happened? Another clue is this...I have had to replace the center bearing 2 times within a year. I had put the driveshaft in a vice to hold it while I removed the center bearing off the shaft spline. I think I squashed it a little and the shaft is off balance a little bit. I also busted off one of the studs of the six that the differential bolts into.
I don't think the clutch has ever been replaced.
