Hello guys, I am struggling with this awful idle issue on my 1998 A3 1.8T.. I have tried unplugging the MAF, cleaning the TB, resetting the TB, replacing vacuum hose, checking all other hoses for leaks/splits etc. Still the problem persists.
The car will hunt for a few seconds then settle down, however if I coast along with the clutch pressed down, the hunting will continue until I come to a standstill!?
Any help or ideas would be appreciated.
