Hi, I'm new to the forums. Ive owned vw's my whole life and done all repair/mod work myself. Ive been on vwvortex for about 6 years. I just got a 2000 S4, so here I am.

So I pick the car up from the dealer and 6 hours later the check engine light comes on. I hook up the VAG-COM and it is a P1122 O2 sensor code (and one other I cant remember). So I call the dealer and since its under warranty they are going to fix it. Fast forward 3 days and I'm driving along, all of a sudden the lights on my dash iluminate (brake, abs, etc. ) then I hear two beeps and they all shut off, including the CEL. I havent vag'd it again yet but I was wondering if anyone knew what this was. Did it reset for some reason?

Thanks in advance
