EPC and traction control

[gixxerk4600]

driving home from work today and my traction control light came on along with my EPC light, i lost power and started slowing down, once pulled over the engine would tick over normally then a few seconds of shuddering and normal and so on. i tried revving and couldnt get it past 3000 rpm. the lights have now gone out and on tick over everything is fine, i rev and all is fine but when i take foot off accelerator it goes down to tick over, then feels as if it is going to stall then the revs pick up to about 1200-1300 for a few secs n then down to tick over n almost stalls and revs again and keeps doing this! what the hell is up with it!!!!!

bloody electronics

thanks

what model is it?

1.8T ?

Could be faulty Dual temp sender or MAF.

the temp sensor usually makes it erratic only when cold. The MAF cause flat spots. A check with VagCom would help to narrow it down if you can find somebody with it. I was going to suggest coilpacks but if you turn around and say its a diesel then maybe not LOL

2003, i think i found part of the problem, i fitted a replacement filter from bmc and they supplied me with a foam washer which was sucked in and caught around the butterfly!
