    Strange Idle/Rough - Intermittent

    Hi,

    help and advice please folks??

    I have an Audi a3 3.2 v6.

    Following various vagcom scans, I replaced the MAF for a genuine Bosch air flow meter after some intermittent running problems.

    Now, when I'm driving it usually only when it's warm, I come to a stop and the revs take a couple of seconds to drop down to its idle point, making pulling away uncomfortable/difficult.

    I had an episode last week where I would start it up and it would die immediately unless it had revs!!
    This problem stopped, I am sure it is related.


    Car is still drive able, but not enjoyable.


    What does this sound like???

    Think you can adjust the idle don't know how mine idles at around 640rpm I had a rough idle before I had the audi software update however I still don't think my car idles perfect I take it no codes were logged and the basics are ok like fuel and air filters throttle body alignment is probably not a bad first point of action though along with a clean in case it's sticky

    its easy to do it you self I think if you disconnect the battery for a while then reconnect it and turn your ignition on the car will align its self only take a minute you will hear the high pitch noise

    Don't always presume the garage will do that.

    And to adjust idle on my TDI is as follows..

    Ignition on - engine off

    Select Engine controller 01
    Select Measuring blocks 08
    Select 'Go' in Group 1
    Start Engine ( you may be able to start engine earlier but I don't )
    Hit 'Turbo' button at top of page
    Select 'Done'
    Select Adaptation - 10
    Change channel to 06 and hit 'Read'

    However maybe slightly different for you.

    Also, what fuel are you using? This has been a known problem for cheap fuel.
