Hi All,

My cats on my 97 A4Q 2.8 have been rattling like a rock tumbler. I
have ordered a new set; but, in the meantime, my check engine light
just come on last night. Everything else looked fine. Does this have
some broader implications; or will this go away with the new cats?

Thanks,

Aaron

Hard to say unless you provided us with the fault code(s).

I do. I just had my 1993 90 CS driver side Cat changed. Your engine
control unit is not happy that it can't get rid of exhaust. Your car
will eventually crawl to a halt. However, Audi Service guy told me
that engine computers are smart enough to know when to shutdown and
you don't damage anything.

I would advise not driving the car if you can.

New cats will make for a new car!
