I am concerned with the safety involved with the catalytic converter on my Audi A6. My check engine light appeared and I took it into my local mechanic who showed the fault as the catalytic converter. I then took my vehicle to the local Audi dealer where they insisted it was the oxygen sensor. I then had this replaced and Audi verified that everything was correct. Once again my check engine light appeared 200 miles later and I took the vehicle back to the Audi dealer. I requested that they check the catalytic converter again and they insisted that it was once again the oxygen sensor. The warranty on this part is approaching the end. I asked, "if this is once again replaced and the light comes on again in a couple hundred miles, my warranty will be up, will you cover it? their response was, "if it is one mile past the warranty, we don't have to cover it." From this comment one would conclude they are giving me the run around until my warranty is up so they will not be held responsible. My concern is that Audi is failing to comply with a federally mandated warranty. They simply do not want to replace the converter which is placing my life in danger considering a car can catch on fire if the catalytic converter is not working properly.
