Hi, my Z4 clutch is slipping on pulling away in first. How do I know or find out if it is the plate or the whole clutch that needs replacing? Also, is there any value in just replacing the lot, thrust-race and all?
Are you saying it's just juddering rather than actually slipping (revs rise without a proportional rise in speed)? They can judder for a long, long time without being a problem (my 320d has been juddering for about 100k miles.)
