When dropping the kids off at school i stopped the car pull the fob out and noticed when i returned to the car and tried open the car there was no electrics at all. Opened the door with the key and when i tried the fob in the igination there was nothing, called AA out who checked the battery which was fine. Afer about an hour trying everthing the power came back on by it self and AA bloke was puzzlled, the same thing happened agian 3 weeks later and called the AA again and explain what had happened previous so he checked the fuse and relay and found main relay loose(green one) in fuse box and pushed it back in. The same thing happened again yesterday and i checked waht the AA had done and nothing, the power then returned again after about 2hrs bu itself.
Any ideas before i take it to BMW so they don't try and give me some bull about what the problem is.
