Hi VagPro!
Problem solved. I quite sure.
When I thought about the fault codes and used VAG-COM to test the components with a multimeter all looked good, but still no response from the roof. (Except the fault codes as above)
Looked at the Current flow diagram and realised that there are two separate earth points. 202 and 601. These are the only ones I haven tested.
And guess what - The relay didn't have good connections in to the relay harness. One of the was almost lose. Bending the fingers of the relay and that did the trick. It all works.
I hope this can help someone with a similar problem.
Thanks VagPro - for the information - You are the man.
