krashot Posted June 9, 2020 Share Posted June 9, 2020 Hey guys! I need help for my Audi TT 1.8T 110kw AUM On diagnostic delphi i am getting the following fault codes; 16519 - o2 sensor 17511 - Lambda sensor 16711 - Low Signal Knock Sensor block 1 So when I remove those errors, the car is going perfectly but after 5 mins, errors show up. I've tried to switch the Knock sensor 1 with knock sensor 2 but still getting error on block 1? I've checked the N75 and replaced, still same I have also replaced the spark plugs, timing belt, water pump, oil etc.. Any advice? Thank you Quote Link to comment Share on other sites More sharing options...
Steve Q Posted June 10, 2020 Share Posted June 10, 2020 I'd replace the parts it advises have failed I've also read that a failing the most can cause the lambda sensor fault. And wiring issues can cause these faults. We're checking. Cheers Steve Quote Link to comment Share on other sites More sharing options...

As I switched sensor 2 with sensor 1 and error still appeared on Knock sensor 1 Thanks Steve for your prompt reply Quote Link to comment Share on other sites More sharing options...
