TDi Flat spot

Discussion in 'Diesel forum' started by imported_YOGi, Oct 25, 2004.

  1. Hey guys, we had a golf mk 4 TDI towed into the garage I work at. The turbo was completely shagged spitting out oil etc. We changed the turbo, cat and the MAF. The car seems to be running fine however there is a small flat spot in 3rd gear at around 2500-3000 rpm where the turbo seems to cut out. The car has been severly abused probably from day one (that appears to be how they broke the turbo) and it has around 6k on the clock. Has anyone got any ideas why there is this flat spot?

    Thanks YOGi

    6K and its already dead, what did they do drain all the oil out and replace it with sand ?

    Flat spot could be:

    A leaking hose
    Wastegate jamming
    Dump valve
    ECU fault
  4. Yeah tell me about it, its a shame because it is a nice motor!

    I've heard about quite a few golf TDI's with knackered turbos after only a few miles.... must be a bad batch
  6. Cheers thanks for that mate.
