O2 sensor codes
2000 A-6 2.8l
The CEL light is on and Im getting codes 17530(P1122), 17548(P1140) and 16544(P0160)
When I check with an ohm meter as per Audiworld tech article which tells you to check resistance at connector in engine compartment, I get a reading below 20 ohms which the article states is OK. The car they are testing in the article is a B5 A4, does that matter? Thanks......

Replace the O2 sensor on the drivers side, behind the cat conveter. The O2 sensor is toast. Those OHM tests only work on specific O2 sensors.
