I have a p0421 code and the car is at Audi right now and I feel like they are trying to take me for a ride. I know the converter is under warranty... but is the o2 sensor if it is bad?

Thanks.

DZA

The dealer said the heater part of the o2 sensor is intermittently failing. He said its not covered under warranty but http://www.epa.gov/obd/warranties.htm says it is.

She is "looking into it" now.

EPA.gov clearly says "Exhaust Gas Conversion Systems: oxygen sensor, thermal reactor, catalytic converter, dual-walled exhaust pipe"

AoA eventually told me that the o2 sensor is covered under warranty and are more than happy to call the dealership if you'd like.

For me, it may be enough that I told him that AoA told me it was covered. He's checking with his warranty advisor. Seems like it might work out for the better.

My tires are bad though... awesome. Mine crack early and often apparently... GO BFGoodrich!

SO DZA: If my rear O2 sensor goes bad, it's warrantied under emissions? Nice!

DZA

Yes, says AoA and EPA.gov (8yrs, 80,000 miles)

DZA

EDIT: I'M WRONG. AoA told me wrong. o2 is only covered under 2yrs/24,000 miles

nothing is covered less than 4/50k, and O2 should be covered to 80k
