  3. Slow and massive judder at idle?

    Engine & Gearbox
    Hi after some help please? A few weeks ago my van (2005 1.9 102ps 137,000m) suddenly went really slow as if there was no boost, had a look and found that a boost pipe had popped off the near side of the intercooler due to the little nipple breaking. I replaced the pipe and although it was...
  4. Mass Air Flow Sensor Problem

    Engine & Gearbox
    There are a lot of useful threads about this common problem, but I would still appreciate help. I have an R reg 2.5 TDI Caravelle (150K) with a Pierburg MAF Sensor. About 4 months ago my van suddenly developed the standard problem that it had little power, especially above 2000 rpm. My (non...

    I'm looking for the right MAF sensor for my 2.5L, 88bhp, AJT 2002 van. (I have searched on the threads but MAF is too short to search on etc etc) The Bosch one I have at the mo has F 00C 2G2 055 on it which only throws up use on a Seat Toledo on the web? Have I got the wrong one in it? :*...
  10. Cleaning MAF sensor

    Engine & Gearbox
