I have a 96 audi cabriolet. The check engine light came on and my friend
at a local service station (non-audi) plugged in a tester and it said
"oxygen sensor defective - bank 1 sensor 1."

Can anyone tell me where this bank is and how to go about changing it
myself. recommended parts co., type, where to buy, etc. would be greatly
appreciated. I do not want to specd $$$ by driving 1.5 hours to my
nearest dealer and pay dearly.

Thanks in advance for a prompt reply.

vtskiman,
I'll be the first to say - get a Bentley Manual for the car (not a Haynes
nor Chiltons, they're about as useful as an Owner's Manual....or a Mad
Magazine). You can find new manuals at the nearest dealer or at www.rb.com
or on eBay - you could also post a Wanted ad in Audiworld and Audifans.
This way, you pay $$ now, and then have one of the most important tools to
fix any future problems.
All that said, and having not been any closer to the underhood of a Cabrio
than a block away, the OXS sensors are mounted on the exhaust somewhere
between the block and just after the cat. If one has failed from old age,
it's probably best to replace all of them (2? 4? I dunno). They're also
$$$+ at the dealer's parts department, but they're cheap at your local FLAPS
if you know how to order a generic n-wire (3 or 4 wire? I dunno) sensor and
splice it into the Audi harness. You may need an oxygen sensor socket
wrench, and be good at contorting because they're generally not easy to
reach nor remove.
Cheers!
