Thanks guys, he's had to leave it with the shippers to sort out as he's got a plane to catch. He's going to talk to the UK shippers and the factory tomorrow.
Tried all the obvious power and ground connections and used jump leads to try another battery. Also bypassed the battery cables by jumping to the +ive insulated post and to the chassis.
He'd already checked the inertia switch and 50A fuse. There's no immobiliser and as far as I know there's no factory fitted battery cut off on the M3W.
The car was airfreighted not shipped so corrosion shouldn't been an issue.
There's basically 13.8v at the battery but absolutely nothing electrical works, not even the instrument warning lights.
Fortunately he's retained his sense of humour about this and is looking forward to getting it going when he's back in Dubai after Xmas.
In the meantime if anyone has any more ideas please post them here and he'll pick them up when he can.
