1.8T 110kw - no boost - safe mode?

[krashot]

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

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

Im just curious for the "Low Signal" on knock sensor 1, maybe something up with the wiring? As I switched sensor 2 with sensor 1 and error still appeared on Knock sensor 1
Thanks Steve for your prompt reply
