When I start the car the roof warning light flashes. I have been able to open and close the roof with no problems.

Warranty ran out 4 weeks ago, took the car to the dealer and they say that I need a new control unit. Audi have agreed to pay for the control unit but I have to pay for the labour - which seems to be the equivalent of a day's work - seems a bit excessive to me.

Any ideas if they have diagnosed it correctly?

Thanks
