TPMS+EPC+Stabilization Fault codes
While driving got the following dashboard idiot lights warnings TPMS + EPC + Stabilization Fault + Engine light. Read somewhere that EPC is related to battery voltage. Rested overnight voltage is 12.34 VDC. I read online that it should be around 12.5 VDC.

12.3V is 50% charged. Not dramatic and not the case here.
What do the fault codes say? It's an important clue to what the problem might be.
If you don't have a fault code reader, borrow one from someone who does or buy your own. A basic reader is not expensive.

The problem I experienced was due to misfire because valve cover gaskets were leaking oil and fouling the spark plugs. Replaced all spark plugs and coils and valve cover gaskets and all is well.
As far as the reader goes,I ended up getting X-tool D7 because in addition to the Audi, I have a Toyota and a Lexus. But I think I'll end up getting Ross Tech product. It happens to come from near where I live.
