Dam problem is still there, fine in drive but banging into reverse when selected causing all gear select symbols to be in red boxes! Hope it's not the ecu as above!
Where is the gearbox ecu as I hope it's not in the passenger side floor where my water leak is causing floodage!

TCU is in the engine bay box next to the fan, so should be less liekly to flood, but could have some water in there.

ECU is in the (sealed waterproof) box under the bonnet - passenger side in front of bulkhead beside the air intake.
There are several in there; I think it's on top.

Sorry to say, but this sounds to me like one of those pesky O rings has gone, which sadly means the gearbox will either need stripping and refurbing, or a reconditioned exchange box.

If that is the case, definitely wouldn't do a fluid change, it won't make it any better, could make it worse, and will cost you about £300 for nothing

Have you got the fault codes from Vagcom yet?

If we know what the fault code is we may be able to narrow it down.

Had a similar issue with my A4 Cabriolet. Multitronic Box.

Flashing gear select indicators all at the same time on the dash mean that the
Box ECU needs replacing....

Very costly.... I shipped mine to a company in UK that repair them for a fraction
of the dealers cost for a new one....
