Dashboard is off course showing less details: default urgent brake, default stability, default EDB, default engine,...
Looking at your fault codes,a circuit short to ground is going to be highly significant if not the major problem.Short to ground – A short to ground refers to a current flowing from the circuit to the car body. Wires may chafe and shed their insulation, contacting the body or engine. A short to ground can result in blown fuses, inoperative lights or motors, or “missing” sensors.
Any blown fuses?

No blown fuse and all lights ok. I agree with you. Seems to come from a BUS communication default but I did not find any damaged wire so really difficult... JM

Hello,
I'm here to give you some news about the disco 4 repaired at the dealer's: It was just a blown fuse!
Unbelievable as I had checked them one by one... so stupid 
Finally, nothing serious, that's the main thing.
For the gearbox fault, it was the solenoid to be replaced.
Anyway, thank you for your help.
Have a good trip. JM

In fact the fuse was even not blown !
when I checked all the fuse one by one I just put one back in a wrong slot (just the next empty one) and did not realize my mistake…
I know, it's so stupid! JM
