I have a 2000 Audi A6 Quattro with 2.8 engine.
Got a P0154 error code reading %26quot; O2 sensor circuit no activity detected. Bank 2 Sensor 1%26quot;. Would you please tell me how to locate the sensor and replace it?
P.S. Don't know if it helps, changed battery recently (shouldn't be low battery voltage), not changed time belt yet, 89000 miles.
Thanks for any help in advance.. .How to change Bank 2 Sensor 1 O2 sensor on 2000 Audi A6 2.8 engine?
It is on top of the cat located just behind the engine stuffed into the engine bay under the fire wall. PITA to get to.
I recommend purchasing a bentley manual. www.bentleypublishers.com or www.ecstuning.com and going to www.audiforums.com and signing in. You need to be on a thread to get better help.
Bank 2 is the drivers side (if your in the US) 1st sensor is on top of the cat.
see you at the forumHow to change Bank 2 Sensor 1 O2 sensor on 2000 Audi A6 2.8 engine?
Since you really need to get that timing belt done (no, 105,000 will be too long), let the shop tackle that issue as well.
