Last week my car started in our frigid weather here, but when I went back out, I had flashing CEL and strong smell of Gas. Finally into the dealership today and they said car was flooded, and O2 Sensors need to be replaced. I have 64k klm (40ish k miles) on my 2000 2.8 V6 A4. I am told about $300 cdn each and need two, and expensive to replace.
do costs seem right?
They pulled the spark plugs because of flooding, what I can't figure out from that morning is did the flooding fry the O2 sensors, or did the O2 sensors crash , flooding the car, killing the O2 sensors? Thoughts ideas? on both costs and reasons.
It just seems a little early for sensors to fail.
Thanks for any input....

probably a bad maf or coolant sensor

go to napa or carquest if you have it and buy whats called a universal o2 sensor. most o2 sensors are the same. you pay for the stupid plug that connects it to your car. This method intitles you to splice and connect the new o2 sensor to the existing plug and vuala!!! works. this is really easy as the o2 sensor gives you directions how to connect and has all hardware needed. i recommend as howiw does, cheap fix for the EXACT same part!!!!

Thanks for replies. Car seems to be working fine, not throwing a code. Maybe won't have to replace sensors after all. While aftermarkets are cheaper, does anyone know what it takes to install these on the 2.8 (2000 triptronic). Dealer sort of hinted that the motor and tranny may need to be dropped a few inches to get at them (the 2 in front of the cats). Doesn't sound like a very easy DIY. anyone have experience with this?

if you use non OEM you just splice them in..much easier
