Electrical problem

[Scottie Tiger]

Hi, my 260 has several electrical problems but they all came on at the same time.
1: Driver information screen gives normal information, speed etc but no longer shows door open, bulb out information.
2: all warning sounds have stopped, lights on, door open, the ticking noise when indicators are on
3, no green arrows when indicators are on
4, car unlocks via fob, but won't lock, same with key, will unlock all doors , but only lock drivers door
5, stereo head unit, gps.. no longer has welcome screen, screen and radio do not work, but there is power to it as you can load and unload discs in the head unit.

All these happened at once, taken it to an auto electrician today and he ain't got a clue, he's fixed all my other cars no problems


I need some help here! Any ideas?

There is no water in the boot, there in no water in the drains, sunroof doesn't leak etc
