Here are the faults I have (read via IID Tool)

U012-00 Lost communication with ABS control module
B1B01-87 Key transponder - Bus signal/message failure
B108B-23 Start button circuit A - general signal failure - signal stays low
B108C-23 Start button circuit B - general signal failure - signal stays low
C1B14-11 Sensor supply 1 - General electrical failure - circuit short to ground
U3002-81 Vehicule identification number - Bus signal/message failure - invalid data received
U0128-00 lost communication with parking brake control module
U0416-68 Invalid data received from vehicle dynamics control module - algorithm based failure
U0415-68 Invalid data received from ABS control module
U0122-87 lost communication with vehicle dynamics control module - Bus signal/message failure - missing a message
U0122-00 lost communication with vehicle dynamic control module

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...

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 Big Cry
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.

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!
