unable to smog 2001 TT due to sensors not resetting.

What is your question?

Number of non resetting sensors appear between 2 and 5 when checking with OBDII tester. Have put on over 500 miles attempting to reset sensors. I have replaced all O2 sensors and exhaust cat convertor.

How long has your 2001 Audi TT Quattro had this problem?

one year
