Audi A4 1997 Quatro (2.8 12V)

Do I need 2 identical before cat o2 sensors or just one?
I'll be happy if you could direct me where to buy them from.
I got these 2 codes:

16538 P0154 - 92-00 - Oxygen (Lambda) Sensor B2 S1: No Activity
17514 P1106 - 92-00 - O2 Sensor Circuit (B2-S1) Voltage Too Low - Air Leak

try autohausaz.com - looks like you only need one pre-cat sensor.

Shoot me an email if you would like to order, or give me a call, the number's below. :-)

However they typically wear at about the same rate, so if you're up in the mileage, you might consider changing them both out as they're both going to be wearing reasonably equally.

We carry these in stock as well.

How many other forum advertisers do you know that would say that? :-)

His price is lower than my cost from Audi!

Mike, which one would I use for my 99.5 1.8tq, pre-cat? Looks like only post cat on the site...

Thanks a lot! I just ordered one O2 and one coolant temperature sensor - you had a good price for the latter too.
Hopefully they will ship'em fast.
Thanks again!
