high idle-faulty throttle body

[gtimk5]

Its a regular service thing to clean out the throttle body by taking off the intake pipe and cleaning around the butterfly area with something like "Wynns throttle body cleaner" in a spray can and using compressed air. A soft rag while holding the butterfly open aids this as well but be careful not to damage anything in there!
Also, check for any air leaks.,...
Get it checked for fault codes is a neccesity.

thing is this doesn't happen all the time. it happened yesterday and before that it was 2 weeks ago. i fear that when i bring the car in (probably monday) she will start behaving and the mechs won't be able to see anything wrong with it?!

ope126: don't really use cruise control so not sure, will give it a go and let you know. yeah no hard feelings mate.

gpk: engine works as it should (revs drop after a minute) most of the time. the car has always run on 98 ron, i assume bad fuel can't be the problem? very particular with fuel so only use bp ultimate or vortex. i'm a complete novice when it comes to working with engine related issues, should i try to clean the throttle body myself or is it safer to bring it in? re the vagcom check, would there be a charge to get that done? i'm in the eastern suburns melbourne, i service at barlowworld glen waverly.

turns out it was a faulty throttle body. the car was a few months out of warranty but the dealer replaced the part free of charge. just fyi...

[ope126]

Well done if that is the case...
I was told that these are $1500 parts (throttle body)

gpk: when i initially told them about the problem at my last service they reset and cleaned the throttle body, but since then the problem recurred (after being ok for about 3 months) so they replaced the faulty TB this time round.

I have a couple of mates at the main dealer and apparrently VW usually change em under warranty, but often if cleaned they are still operational.
I`d definately try that first as they are dear.

Is the snowflake not a warning of possible icing conditions. Used to get one on my Passat in the UK for that reason. I bet it would mention it in the car handbook.
