Cooper D reving faster than engine speed
My 2007 cooper D has just started this problem, it has 106,000 mile and is a manual.
It doesn't matter what gear I'm in if I floor it the revs will increase rapidly to about 4,000 rpm and then settle down. Even though the speed is only increasing slowly. Obviously it's most noticeable when in 6th gear doing about 50 and put my foot down and the revs go sky high but the speed does nothing.
