FIRST CODE:

Error code: (17511) O2 Sensor Heating Circ.,Bank1-Sensor1 Output too Low

I Changed both O2, Before and After Cat. O2 sensors because both looked jacked....

After replacing sensors, a few days later check engine light came bck on.

I checked if everything was connected correctly and tightned everything......few days later, Light check engine light came on again with same error......any ideas?

SECOND CODE:

Error code: 03167 CV-pump, alarm, RC D16, pump run exceeded, likely leak

Thanks All!

 

FYI - I'm not an Audi expert....but I do have the manual. I'm going to paste the procedures for troubleshooting the first code. Total of five pics. Had to split them up into 3 post due to file size. Did a search for the second code, but didn't turn up anything. If you end up following these procedures, I would appreciate it if you follow up and post results. Thanks and good luck.

Just realized how crappy the text on those attachments is. You can make out most of it, but if you have questions just PM me about the specific section you are having problems reading.
