I have a 1998 2.5 tdi a4 and have recently had the cambelt changed and the crankshaft seal replaced. I have only had it a month and drove it very steadily before the cambelt was done.
Today I took it out and driving up the motorway sliproad could not get any ore than 3000 rpm in 3rd. I then tried reving it in each gear and found all to be the same.
Prior to the cambelt I changed the oil breather filter and checked the turbo (which seemed fine).
I have spent quite a lot on an old car and am getting close to calling it a day.
Can anyone shed any light on the lack of power under load please? Revs fine with no load.
