i think most of the cat failures are mechanical - i.e. they split apart at
the welded joint. you'll know if that happens, your car will sound like a
helicopter. happened to mine twice [first time was rewleded poorly]. i
replaced with a labree high flow [love it].
i haven't heard of many failing due to clogging or wearing out. on the older
cars they lasted forever.
i would get a 2nd opinion - as stated it's likely the 2nd o2 sensor [100$
and 30 minutes].
> Go talk an Audi tech...and ask them how many times they replace A4 cats.
> quite common on VW Golf/Jetta MKIV's w/ the 2.O.
