Hi new to this forum
I've dropped an engine from an 820 turbo into my car and followed diagram and autodata for the wiring but had a bloke over today with his t4 to reprogram the 5as box and nothing!
The car wouldn't talk to it and even using the diagnotic port next to ecu had no power!
Any ideas what's next before a gallon of petrol and a box of matches?
