Hi Guys, I had this fault come up a couple of weeks ago on my S3 (AMK engine). 17511 - Oxygen (Lambda) Sensor Heating: B1 S1: Performance too Low P1103 - 35-10 - - - Intermittent Cleared the code, it came up again a couple of days later, cleared it again and after running through 2 tanks of gas, it's stayed off. I haven't noticed my fuel consumption getting worse - besides replacing the oxygen sensor as preventive maintenance, is there somewhere else that I should be looking at? What else could have caused that fault to come up? I've checked the connections and plugged them in and out - all seems good. Tks!
