System Reset to solve issues
Posted: Wed Oct 13, 2021 8:34 am
Hi,
I have had two cases since I bought the car of major system warnings.
I have solved both with the following procedure, which may or may not work for you
My feeling is that the software is very complex and every so often it gets confused and just needs a reset, like a laptop
The first time we were sitting in the parked car, and a car came by me at around 50 mph, it was very very close and missed my car by a few mm, but the air wave shock hit the car like a bang. Luckily there was no damage. However, for some reason, the car immediately started saying, "major system fault, drive to garage".
To solve this, I reset the infotainment system (20s on on button on left of screen). Got out of the car and locked it. Came back in 15 mins, reset the infotainment system again and all the warnings had gone.
Leaving the car for 15mins is very important, as VW confirmed in advice I read to a customer, as it makes the cars software system go to sleep and do a soft restart
The second time, it was raining heavily and I had left it parked for a bit. Not sure what happened whilst it was parked. No idea if this was an issue. But two warnings came up when I got back in, one that collision detection system was not able to work and secondly that advanced safety systems were offline.
To solve this, I switched ignition off and on. locked and unlocked car. reset infortainment system. Then selected full system reset from the system menu. Note that this said "it couldnt complete" but ignore this. Then switch off car and lock for at least 15mins (I left it 30 mins). When I got back in it was all back to normal. Note that full system reset disconnects "we connect id", and you have to uninstall this from your phone. Reboot your phone. Reinstall, and then go through connection routine from car's infotainment menu.
Anyway just sharing my experience above
