From what you describe regarding your multitronic gearbox, the ECU is knackered. This is a very common issue with them.
The bigger issue with them is that the longer you drive it with the PRND lights on you could well be wearing out your forward clutch.
Does it hesitate when selecting reverse?
Many gearbox centres will replace the ECU (box out job) but with no guarantee.
I have previously dealt with a reputable gearbox centre on the Southside of Dublin. They insist on inspecting the forward clutch and replacement if necessary, before the ECU is replaced. Then you will get 1 years guarantee.
They get new ECUs from Audi in Germany which have been "upgraded" which seems to fix the problem.
