My T5 has just started jumping out of reverse gear, it feels like it goes in reverse ok but when I release the clutch to go backwards it jumps out slightly and sounds like your trying to change gear without putting the clutch in. Can the clutch be adjusted? Or if anybody can give me some ideas what to look at? I did have a small oil leak from the gear box some time ago but soon sorted it out once I saw it. Any help appreciated. It's done 180,000 and had a new clutch fitted at vw about 70,000 miles ago.
