A sudden loud boom sound broke my 'so far no problem' 1999 A4 1.8 Turbo @ 60K miles dream. Now the car sounds like a racer ....without a muffler. But the noise is not coming from the tail but from the front engine compartment. Also exhaust is now circulating into the cabin.

I suspect the catalytic converter. Funny thing is that the engine light warning is not ON. The car drives OK albeit lethargic.

My question to all ye experts are:

Is replacing a Cat something a home-mechanic can tackle after buying parts from the internet? I still remember how tough it was to get the right tool to replace the oxygen sensor.....

What is your experience?


I know Barriar motor (in seattle) will lovemy $1500. I would like to disappoint them.

Sounds like your dp is broken from the cat.

Stop by an independent muffler shop and see if they'll pop it bck in place and weld it in for you?

I had one of the cats go bad. It sounded like a very loud rattle in the exhaust

With some help from you guys I figure that I have a broken cat at flange...very common to A4 98-99. Why shouldn't the deal take care of it under 7/70000K warranty?

Any experience out there with Seattle Dealers?

Thx everyone.

I replied back to you. Dealer should/will replace it under warranty
