Hi all

I’ve been having some issues with my 2015 A7 3.0tb I start up.
I can start the car first time with no issues. If I switch the engine off and try to restart the engine, it will crank but not start the engine?
If I leave the engine off for around 2/3 minutes it will start up with no issues.

There are no fault codes relating to this issue according to the AA patrol.
Crank shaft sensors seem ok as well as fuel pressure (high and low).

I am completely stumped as to what the issue may be. I suspect electrical but no fault codes to go by?

thanks in advance for any advice
