Check engine light on..had the code read and it is listing:
P1127 - exhaust not warm
P1131 - Lack of HO2S switch - sensor indicates lean
P1129 - Downstream heated 02 sensors swapped

Any Ideas whats going on here?

the audi code library is a little different:
P1131 - Bank2-Sensor1 Internal Rsistance too High
P1129 - Long Term Fuel Trim mult.,Bank2 System too Rich
P1127 - Long Term Fuel Trim mult.,Bank1 System too Rich

Does this help?
