Thank you so much.
Everything is almost look like normal: no warning, unless something: sometimes " key ID incorrect", sometimes the door manual lock unlock doesn't work, and if I open the door-back: it opens and closes itself unless I block it by hand. The the steering wheel controls works fine.
I have already checked the fuses, the connectors, the wiring and they are good.
For more information, at the beginning of the problem, the screen went blank when I turned on the engine and then it came back on after about 15 mn of driving and worked well; but it turned back off when I turned off the motor and went back on again after 15mn. So the back on of the screen became longer after and then it totally stopped after few month. It is on but no signal.
So I would to know which relay (may be some contacts carbonized) should I check or if there is some part like thermistor or other parts changing with the temperature over there.
Thank you again.
