A wild guess would be the EGR valve is faulty.

Hi Crasher, Many thanks for your response.

A wild guess would be the EGR valve is faulty.

started the car this evening, (after leaving it approx 24 hours) - Engine management light is no longer flashing. Acceleration/Power back to normal , can behaving as if nothing has happened.

Any ideas ?

[Crasher]

Completely normal, if you have half a dozen codes that say something is faulty, why ignore them? IF the codes were supoted by a G28 crank speed sensor issue that is different.

The car is Booked in tomorrow with Audi specialist, will let you know the outcome.
