Hi All
Hope someone can help my mk3 golf AEA engine is idling fast when warm at about 1100 used to be around 850
If i press the rubber covered spring (marked in the pic) right by the throttle cable housing by the throttle body (see pic)10411 the revs drop to around 850 is there any adjustment on this or do i need to replace the Idle air control valve which is a Bosch 0132008601
many thanks
