recently on a 3 hours trip home my 2001 s4 decided to try to kill me. Was doing about 90mph when all 4 lights came on, and the car basically shut down in the fast lane. Exciting! In the pouring rain to add to it. I made it to a parking lot and the EPC light, traction control, and ABS light would not turn off. Went back the next day for it when it was not hurricane weather, and the lights remained on, and the car was idling randomly. I ripped off the ecu cover only to find some condensation on the cover, which ive read may had caused the EPC light. I will be pulling the codes tomorrow morning, but looking for some quick areas to look into. Ive read that the speed sensor in the brakes could cause abs and traction control, but unsure. Will post the fault codes asap

Post up the codes and we can give you an idea. You listed way to many variables to give you an answer that could be anything beyond a guess.

P1127 : long term fuel trim mult. bank 1 too rich
P1113: HO2S 1 BANK 1 HEATER RESISTANCE TOO HIGH
P1129: LONG TERM FUEL TRIM MULT. BANK 2 SYSTEM TOO RICH

Recently cleaned the MAF also. I am trying to replace the S1B1 O2 this weekend. Just had an alignment today, and abs and traction control lights come one together, but randomly while driving. Not really understanding the abs and traction control though.
