Does the flash have to be done at the factory? Living in Switzerland it's a bit of a schlep.... I'll chat with the dealer here and report back...
The dealers can do it, and also the factory do it by post. I looked into the abyss (the electrics box) saw the layout......which was like looking into an open chest on an operating table, and decided to take it to the factory rather than extract and replace without damage.
