I seem to have a problem with my ASR. When I am accelerating or even at a constant speed the car seems to be holding back and jerking like the ASR is functioning when it shouldn't. Today when I went out in the car the ASR light came on the dash and stayed on permanantly. Has anyone else had this problem or knows what it might be?

When I turn the engine off and on again the light goes off again. Then the problem re-occurs. If I tried to hook up VAG-COM, would this throw up errors do you think?

The ABS sensor ring being damaged could cause this. I had a sensor fail but had different symptoms, the ABS and ASR lights where lit. If ASR (which relies on ABS) is kicking in then I would take a guess that it is the ring rather than the actual wheel speed sensor and this may not show up in VAG-COM.

dirty or faulty MAF

i have had a new maf fitted and not solved the problem. Skoda said it was a sporadic high or low sensor readings from the maf. Even with the brand new one fitted. They've also checked the wiring which is all ok too.

Any other ideas are welcome as they say nothing else is coming up on vagcom.

Back a few years ago a simliar problem was occuring on 2 of our lease Golf TDi's (02 Reg) The one was fixed by VW remaking a connection on the alternator while the other was needing a new alternator altogether. Seeing as the one golf that had its connections checked and sorted worked after this, see if theres anything obvious around the plugs on the alternator.

on my way to jabba to see if they can find the problem. Fingers crossed.

Did you get this sorted mate?

Not yet:( They said they don't know how I managed to drive it 2 hours to them, so they have kept it. They think that it might be the ECU. Waiting for a call now to see the rusults of their labour.

I had a similar issue last week after i had a remap. The car keep dumping boost as it was trying to hold onto too much and in turn put the ASR light on. Turned out the nut on the end of the wastegate actuator rod needed winding back slightly.

Might not be your problem, but certainly worth checking.
