    So i was out and about last night with my mate, we parked up for half and hour and when it was time togo, key in engine turn once power up turn again engine on, went to go into reverse to find no rev's, the engine had cut out, so everything off and try again, when i started it again it started chokeing then shot up to 1500rpm then back to 900rpm and bounced up and down 100rpm then was fine! ran the car all night and all day today and it hasnt come back all though the car is now idling at 1100rpm instead of its usual 900rpm, any ideas? Dont know if its worth mentioning but the car had 1/4 tank of super unleaded in and i filled the rest up with normal unleaded last night.

    Cheers Dan

    If its not mapped I dont think it will be the fuel as I used to mix between poor mans unleaded and premium all the time.

    Fuel wouldnt have that effect even if it was mapped, sounds like a sensor issue to me

    Its been known to have side effects tbh on some maps if you mix the fuel if its been coded for better fuel, like say revo dongle sets for different fuels & you mix them about, not unknown mate.

    But isnt there an idling sensor on the 8L as I do remember someone saying to me once when I had my S3

    Sounds like maybe a vcds check needed for any logs, check stickies for local boys to you who would do a check, if near me I'd happily do for you mate.
