your second o2 sensor is bad or your cat is shot

I had that code on my 98 1.8t. Dealer replaced the cat and o2 under the extended 8 year 80k mile emissions warranty, so I can't say which of the 2 were actually bad. I'd do some research to see what year 1.8ts cats will fit your car. Most likely all b5s will fit, but I'm not sure. There are usually people selling their old ones when they go with a high flow one. New they are about $800 from the dealer so you don't want to do that.

For what its worth - I got this for several months before my cat went bad. I would reset it, but it would always come back.

Usually this code will pop up with the secondary or post o2 sensor being done with. Worst case scenario it can be a cat. Meow
