Audi A5 ignition problem

[kwaka jack]

Evening,

I'm after some advice regarding my Audi A5. It had come up with a error code saying ignition system disabled. I've done a google search and there were a few ideas that came up all of which had not worked. Its booked into Audi on Monday to be checked over. Just wondering if anyone else had this problem and knows of any of things I can try before it's sent in.

Many thanks

Jack
