got an S3 8L: living the dream
EPC Light! Eeeek! Help! Any bright ideas?
Wondering if any of you can shed any light on this for me? (I know the main answer if VAGCOM but I have to wait for my friend who has it to get back off holiday).
I was driving home from work last night, revs at about 2.5k-3k rpm when suddenly the revs dropped to about 1000rpm and then it cam back up to where it was. The EPC light came on. The car was driving smoothly apart from that one dip in the revs. All sounds ok.
When i got home i turned off the ignition and back on again....the EPC light had gone out.
With this I had already decided to ask my friend about looking up any fault codes etc.
This morning, all seemed well and smooth and sounded as usual......Then when pulling up to a junction the revs just died. Took a while and a couple of attempts to restart but eventually did.....with the EPC light on. Again.....all sounds smooth and fine.
The manual says that the EPC light comes on when there is a fault with the engine management system and that the ECU will revert to a backup. I presume this is what happened the first time but the second time the revs were insufficient to keep the engine from stalling.
I hope to be looking at it on VAGCOM this weekend (fingers crossed) but wondered if the wealth of knowledge on here could shed any light on it at all? (to my mind it is likely to be almost anything, but software related if it is capable of running a backup ok.)
