I have a 2.0T Quattro B7 auto and over the past week it started to jump between gears, other than that seems to be fine. Its getting on abit at the moment, its a 2005 with 115k. On my MOT they noticed some oil on the read diff, but in the service they said there was nothing to worry about. Anyone any ideas what to look for and what I should do? I was thinking of giving an independent specialist a call and ask them to do a running gear service. Check all suspension, drive shafts, gear box and change the fluid and seals on the rear diff. Any idea's on how much this would cost?
