Poor hot starting

injectors are dirty / leaking. Try some Techron injector cleaner.

Also suspect the engine temperature sensor.

Hello

Does the engine often stall, when it runs in idle rpm? I guess your car has an vacuum leakage in the intake system.

I have managed to fix a similar problem in a 2001 A4 Avant (8D), but it had to do with a temperature sensor malfunctioning, causing the engine to flood when starting hot. See thread about this, that I started on 20 January.

YMMV since your car is a very different one to mine. /Robert

Had exact problem with my Audi A4 1.8. Was indeed the temperature sensor - thanku,problem now solved...slightly lumpy still tho...hmmm!Cant part a girl from her Audi!!
