after a bit of help/advice.
recently i have noticed that when i first start the car up in the morning (or at the end of work when it has been sat all day) the rev needle seems to "hunt" slightly up and down a bit, this is before the engine is warmed up and revving around the 1000/1100 rpm mark, i can also slightly hear the engine revving in time with this movement.
also, when the car is up to heat and say i am sat in traffic, sometime the revs will drop to almost 500 (seems to sit at about 700 rpm normally) and the car almost stalls.
i think there is also some hesitation accelerating and other little niggles which may all be related. I assume the common response will be "clean the throttle body" which i will be doing, i just dont have VAG com to reset it. I also wanted to know of any other possible causes.
