Before the dealer, an ASE certified repair facility specializing in BMW and Mercedes Benz told me the catalytic converter has 5 inch long hairline crack on top part of curve on driver's side. Dealer claims Catalytic Converter is not cracked and that the sensors are bad. The only code was P02098. I did not see a code for the upstream bank 2 sensor. Dealer claims other codes would be present for bad catalytic converter.

I will be extremely UPSET if I replace both sensors to find out the CEL still comes on and throws the DTC P02098 because of a 5 inch hairline crack in my catalytic converter. The catalytic converter from Chrysler is $1355 without labor and the cat converter is supposed to be covered by the 8 year / 80,000 federal emission warranty.

Last question: Dealer has ordered the two Mopar sensors (P/N 5099820AA and 5099821AA) from detroit warehouse, since they had none in stock. $544 each plus labor. We are still waiting for them. If I refuse these sensors, can dealer charge me for a restocking fee or other such nonsense???

I found the 02 sensors (Bosch) at RockAuto for really good prices...

Thanks!!!
