Title: car keeps cutting out.
Post by: km on 27 September 2010, 19:20

anyone fancy solving this?

got a 1.8t agu. doesn't cut out all the time, usally once every fortnight maybe? but it's done in 3 times in the last 5 minutes. getting very frustrating. and when the car's idling, the revs like to drop and shoot back up. and sometimes, the throttle pedal seems to do nothing, it's almost as if it's been disconnected. for example, i'm driving along in 3rd, change to 4th, but the car doesn't build up any speed. sometimes the car just stops for a split second (very similar to tapping the brake pedal)

any help will be appreciated thanks.

Had car at r tech about 2 months ago, and they cleaned it I think. Still think it's worth a clean? Think it could be anything else causing this? :/ thanks

I did have a spit nose pipe runing from my N75 once that had simler things happen to what you have said KM, but not as bad. But i think a falt code would have crop up by now it that was the case but maybe work having a look?

hmm, happened again today. had my foot fully pressed on the accelerator pedal and car was just rolling, no acceleration. I have to let go then press again in order to get it to work. put the clutch down.. and the revs just drop. i'll order a vagcom cable off ebay now  :undecided:

You need the cable off ross-tech website for full edition otherwise it wont let you do hardly anything on the free edition and to get it to work with a 3rd party cable is a right biatch..

ah thank you so much. was just researching into it. luckily i haven't purchased the cable yet. so am i right in saying the free version is mainly for reading codes etc. full edition software is a bit pricey for me atm. it will have to wait :)

Post by: tech1889 on 28 September 2010, 15:42

the free edition will only let you read codes i dont think it will let you even erase codes..
