If its a cable operated TB, then it will reset itself after about 100 miles, if its the other (electronic TB) then I think you  need to re-align it with Vag-com.

and before you ask, you need the full version of vag-com (vcds) to be able to re-align

my 1.4 did the exact same thing when i stopped at traffic lights the revs would drop them jump up then drop so low it would cut out, paid £10 for garage to clean throttle body and it never did it again, you can do this yourself theres a guide on how to do it on here but for £10 i just got garage to do it. that would be first thing id advise you to try  :grin:

yeah im 98% sure its electronic. you may not have to realign, it may sort its self out after a few miles.

I would say clean tb first. it doesent cost as much as a maf sensor :D

i was initially thinking tb but then thought well i know mines down to the maf and having the same problems so thought ide mention that.

Hey guys i cleaned the throttle body and she is perfect :) The throttle valve was black as ya hat. There was no need to use vagcom just left ignition on in position 2 for about 3 mins and then run her up at idle for a good 10 mins and she is smooooooooth :) cheers guys

The 1.4 doesnt have a MAF.  It also came with the cable and electronic throttle body.

They do suffer from dirty throttle bodies though.
