Went to the stealership and had the plugs and wires done @ 135M. They retrieved the SES code telling me that Bank 1 Sensor 1 was bad. They wanted an additional $280 for that one. I decided to tackle it myself. I purchased the sensor from Rock Auto for $50, should be coming soon.

Found it, looks like easy access to me. Plug looks simple too. Any gotchas from the pros here?? Unhook it, wrench it off, discard, add some anti-seize to the new one, screw it in, hook it up. Done deal.

The computer will reset itself right? Thanks. Mark

 

Check the wires for any damage while your there.
I usually disconnect the battery, then hook it up again when finished to reset codes.
