    Engine & Gearbox
    Hi, I'm trying to help a friend out who's got problems with his petrol T4. When the engine is idling, there is a hiccup every 10 seconds or so. When the engine is warm and under load, it looses power. You can feel the power dropping away, the more you press the accelerator, the worse it...

  10. Follow up about Idle Air Control Valve

    Engine & Gearbox
    Hi guys I posted a few weeks ago about my van revving up and down by itself. Someone suggested that I clean the Idle Air Control Valve (IACV) with carburettor cleaner. I did this but it didn't solve the problem. Basically what happens is when the IACV is connected the van starts perfectly but...

    My diesel pump decided to start leaking and kill my alternator. Anyway all sorted now but is it possible that something needs adjusting as it seems to be idling higher than it used to. Cheers Sim (1.9td ABL)

    General Technical
    I've got a 2.5TDI Caravelle. (2003 T4). Do I have to Idle the car for a while when I stop, and if so, for how long. Somebody told me it's to cool down the turbo. Is this necessary?
