    hello guys,

    i have a 1.6 A3 1998 model.

    low end revs are bouncing and can stall whilst slowing down. is this issue to do with the idle valve or something else?

    also what would the cost to rectify this?

    thanks in advanced

    Graham

    do a search mate, a common issue - air related so first check your air intake system

    Temp sender would be the best place to start, sounds like it's giving the ECU duff info. The ECU will adjust the fuel/air mix based on this duff info, so stalling, bad starting and idling issues will result. A new one is only £20 from your dealer and is an easy DIY fit.

    Do you need to reset anything when replacing the temp sender?
