Sooo ... Home for the weekend and my vagcom eBay cable and disc had arrived so I set about scanning the car and found these codes ....
17705 - p1297 pressure drop between turbo and throttle valve
16795 - p0411 which I found is the secondary air injection
17704 - p1296 which I beleive is coolant mapping?
I did some research and found my n249 bypass needed a resistor so I have cleared the codes and put it in but any idea how to solve the other issues?
I also read the sai plug needs a resistor so will get one and do that tomorrow.
And idea how I could solve the coolant mapping problem or diagnose it as I can do measuring blocks now

Also got a big delivery from the postman including this intercooler

so may do thr tommorrow.
