Anyone here done a TDI-into A4Q conversion?

[Westyman]

I'm about to dive in head first, 130hp pumpduse into my A4. Everything looks
straightforward, except a bit worried about the CAN-bus, or lack of it since
I don't have a TDI dash yet. Is it necessary to run, or more importantly, to
diagnose via 1552? Not my first conversion, BTW, I'm fairly experienced when
it comes to diesel conversions, just haven't done a newer one yet. TIA,
Karl
