Hi. This is my first post here.
I have just experienced an issue by many who have no issues during warranty period then bang the problems start (post warranty)!!!
Anyway, this time I have my Q7 2009 TDI immobilized with a potential start authorisation ECU issue.
SYMPTOMS
No central locking
No instrument lights showing on dash
Air control lights up and so does MMC panel
Car will start for 1-2 and turn over but will fail and shutdown
The three keys I have have been tested and neither will start the car so issue not the key
I had the car towed to AUDI dealership up the road and they have run the diagnostics to determine that the errors leaded to J815. This appears to be the ignition coil however Audi are claiming that both it and the ECU need replacing?
Error messages from report as follows:

I am seeking to find out if what they are suggesting is true and I am up for a lot of $$$ or can the ignition coil be replaced assuming the ECU just can't communicate with it.
Thanks for your help
