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.
