Default RE: Random Stalling + Codes (fixed!)


replacing the MAF seems to have resolved major problems that my car was having idling.

Just incase someone actually searches here's the updated info and logs.

The trim is fixed! I was able to watch the trim adjust on vag-com real time. Awesome.

(O2S control learning curve, @idle -3.1% @part -4.7%/1.6%)
According to the service records the right side O2 sensor is new, i'm wondering if that is the only cause for the difference between the two.

WOT several pulls on to freeway on ramps.
Values much closer to the 80% of max HP rule of thumb now.

Cleared the codes, drove around the block and it came back clean.

My first fix on the Audi and i'm stoked!

Hey, readings at idle really look good! Glad you nailed it! Thanks for providing the MVB info, too! Wonder if google will let them stay up for future searches?
