I know its a post cat O2 sensor, which one there are 250 for the 2, rightor left i need to get this changed because im getting really crappy mileage, I get on the highway and as im excellerating to speed i drop liek 20 miles on the tank. I would really like to just change the one, i know they are cheap for the universal ones but i dont want to deal with splicing and getting wierd codes so im jsut gonna replace with OEM replacements

close but ihave a B6 3.0 i dont know if that helps i jsut need to know if the right of left sensor.

 

Post catalytic converter doesn't affect gas mileage, it only reports on the condition of the converter.

 

Bank 1 = passenger side
Bank 2 = driver side

 

Check the electrical connection to the O2 sensor.

 

can any one give me the how too on changing out the passanger side O2 sensor, and what the hell is that program you guys are running, that lists all that info, is that a newer vagcom or is that bentley manual CD.

 

when I have problems like the ones wit you guys, I just consult my manual and if I really do not get the right solution, that's the time I visit my dealer. Like last month when I can't really figure out why my car produces some ugly noise, I went to the dealer asap. That's the time when my Nissan catalytic converter was replaced, it's a good thing that that's the only problem 'coz I can't afford to replace another autoparts next time...
