    you could try disconnecting the maf, if it idles better then you can say its up the swanny. other than that a fault scan is the way to go

    Have you tried putting some decent injector cleaner through to see if that improves things at all?

    If it's a "audi a4 130 quattro sport ", then it's TDI, so I'm guessing not the plugs ;)

    My 130 TDi had similar problems when I bought it although not the rough idling. When I scanned it it also had no fault codes for the engine.

    I changed the MAF anyway as I know they get worse with age and with the new one fitted I got loads more response and a bit more power but no real change to mpg.

    Next was the coolant temp sensor which made no difference at all.

    After that I changed the thermostat as over the winter it was really struggling to get to and hold at 90 degrees. Doing that instantly gave me about 5mpg increase and the car warms up within 5-10 mins of driving now.

    Still never solved the occasional longer cranking times when starting though. Main thing I guess though is it always starts!!
