Default S6, runs rough & EPC and Traction Control lit

Symptoms are not entirely consistent each time this triggers...but the dash lights up



I think the first few times this happened was under moderate to heavy throttle, and the last time was light to moderate throttle.

The engine stutters, and more throttle seems as if it is fighting against the traction control system (could be my imagination).

VAG shows what I think are a few critical codes:

I did a search for threads and found several that seem helpful:

1) http://forums.audiworld.com/showthre...2762508&page=2
2)http://forums.audiworld.com/showthread.php?t=2796173

Would like to hear your thoughts, but the links seem to point towards a vacuum leak.

I am going to try to nurse it this week and chase it next weekend. Any other suggestions are welcome!

From my experience I can tell you that the low voltage, ABS module and the DTC codes for ABS and ECU #2 are connected and caused by low voltage. Your battery may be going out. I had the same DTCs when it got really cold and my battery was old.

To clear the ECU #2 code you will have to first clear all codes from ABS module. So you will have to clear the codes at least twice.

As for the flap and the TPS that may be related and it's a bad news as the manifold flap must be replaced and it is pretty expensive.

Just clear the codes and then see if the TPS and manifold flap comes back.
