I don't know if this is helpful but I will put it out there. So I was talking with this guy in Italy who was having these Travel assist and Emergency Assist faults popping on and off for 7 months. He decided to find what was causing the problem. He opened up the plastic parts around the back of the steering wheel and noticed a couple of white connectors that moved sideways very easily and decided to use a drop of hot glue between the connecter and the side wall of the steering wheel to stop thd connectors from moving. After 1 month he has had no more faults appearing.
Now if this is a solution for many I don't know but I think it is worth looking into it.
In the photo you see the white top connector but there are more on the bottom also.
