After my first day on the track (1st timer, totally hooked), while waiting on line for the skid pad, my oil sensor went. Gauge dropped, yellow warning. Ok, well, at 108,000 miles (which I hit during the skid pad), I should expect it. I did the whole event in APR stock mode, so I was a bit surprised, but whatever.

got back to the garage, and had this and the EGT sensor 2 intermittent failure. On the way home, turned back on APR 93, starting hitting 21 PSI boost! ABS and ESP lights came on. Ok, back to stock.

got home, had the EGT, a MAF signal too high, *and* the overboost code (max charge pressure exceeded).

My questions are:
1. Should tracking in stock, staying pretty much in 3rd and 4th, never hitting > 6000, cause any of these things?
2. Shoud/would the EGT also cause the MAF, which would cause the overboost?
3. Should/would the oil sensor cause any of the above?

Had *no* DTCs before the track for a while. I had just replaced the EGT about 10K ago, so I'm surprised that went.

Thanx in advance for any help!!

Oh, 2001.5 S4, APR stage I, tip (no tip cracks please), kevlar TBB, 710Ns.

All could be caused by a small boost leak. Pressure test time!

I've had boost leaks in the past, never had an overboost because of one, and certainly never an oil temp sensor failure. I'll take your advice, but I think this may be a dead end.

Not the oil temp sensor, but the MAF could be. Small leaks can cause overboost.
