    Hey Guys! I have an Audi TT 1.8T 110kw AUM MK1. I am getting fault codes P17070 ECM Relay, Knock Sensor 1 Low Signal, Lambda O2 Sensor, G200, VSS...

    The thing is when I clear the codes the car is running GREAT and on very good boost. But after couple minutes, it reads the codes again and it has lowered power....Do you know anything about this? The car has an engine swapped also.

    I have done Timing Belt replacement as it was 1 tooth away, and the engine starts and works good!

    On VCDS, it first reads the lambda fault then the knock
    Please save me!

    Its called limp mode. You should fix those faults which make error codes. Then limp mode goes away.

    Have you had it scanned with VCDS or another good code reader? Its very hard to diagnose these things without fault codes
