Hi all - I am nwew to this forum (obviously), so apologies in advance if I am posting in the wrong forum etc! I'm Will from S Wales who is the new proud(ish) owner of a Tdi Sport Estate. Its a shame that my first post is a plee for help - but needs must! I bought the car from an auction (eek!) on Friday - FASH, 105k, AWX tdi lump etc etc I made it 4 miles before I realised that the turbo wasnt really doing a great deal - and there was a severe lack of power. I also noticed that I was throwing out a significant amount of black smoke and the car would really rev passed 2.5k When I can to a junction after this joy - the car was idling very lumpy and refused to rev at all! (Luckily this cleared after I turned it off and back on) I had it on Audi's diagnostic computer for a few hours on Saturday (with a mate who works there) and the only teal issue we could see was that the AMM was doing some strange readings. I subsequently bought a new one and it was still the same! So to sum up - it boosts OK for a small while when in 1st gear, then it pretty much has no power and after a while refuses to rev. Have tested the EGR valve (and AMM) but was wondering if theer are any maual checks? I have also checked fro boost leaks - there is one potential from the intercooler, but it shouldnt warrent such a HUGE lack of power surely? Help!
