As a response, this is BS and we can corroborate your experience with what happened to us. If you don’t mind, I’ll be writing to DVSA and will quote your reference number so they know that this isn’t a one-off.
We also have AA call logs that can confirm what happened to us as well as the AA technician who literally could not move our vehicle because the steering wheel had locked. All electrics had cut out- even the hazards, but luckily the front two doors were able to open, so I could get out and direct traffic around the car.
How Audi UK is claiming your experience to be a one-off is beyond me; there’s several other people just in this group!
Finally picked up our car today but had a horrible feeling the whole time whilst driving it home. There will be a long period of paranoia now, not too dissimilar to when you’ve been in a car crash and dread getting back into a car again.
