Been advised today that my turbo is worn, 160k on the clock, so its had some use, Saturday I overtook and halfway round the lorry, power dropped and I could only get to 2000 revs all the way home, after I turned my golf off then on again I could get above 2000 revs again, the question is new or refurbed turbo ?? (2.0 TDI BKD engine 2005)
