bought a 2004 A4 1.8T w/99000 miles. runs great but seller said he would fix the check engine light because it was nothing serious; as it turns out the light is on because of either a faulty O2 sensor OR needs a new CAT. Got a quote from an auto import "specialist" for $1900 to do that. Any one have experiene with these CATs in the A4?
