Hello everyone, following my change of steering wheel to a carbon one, I had the Travel assist unavailable and Emergency assist unavailable faults. I searched for 6 months for a programmer capable of erasing them but no one in France to my knowledge. I succeeded in erasing them with OBD11 after several tries, so I share my tutorial with you.
Please note that I strongly advise you to save the original values before starting. I could not be responsible if the procedure fails.
Of course, this procedure will deactivate the travel assist and the emergency assist definitively which in any case do not work with an aftermarket steering wheel (not tested the line assist). But you can of course re-activate them by putting the original values
Successfully tested on Golf 8 GTI 2021.
1. Switch on the ignition without starting the engine
2. Open the hood (if possible connect a charger)
3. Turn off all unnecessary components (headlights, screen, etc.)
During the procedure, NEVER close the driver's door (risk of putting the computers on standby)
Before starting I strongly recommend that you make a backup of the ECUs concerned
