Sorry to hear of your incident must’ve been terrifying. As regards tyres the Enyaq doesn’t use tpms sensors it measures the diameter of the tyre which is why when you reinflate you have to manually reset the system.
I’m guessing it didn’t show anything about tyres as the EV equiv of a pyro fuse probably blew or because the car isn’t driving it’s not showing an error.
I had similar with the RAC I told motability to get me a taxi and they can recover the car without keys which they did. Only hiccup was they sent the taxi to a nearby pub with same name 100 miles away despite me telling them the A road I was on.
Unless RAC are going to be quickish or you have somewhere to go I’d ask for a taxi and unattended recovery fwiw for anyone reading this.
Hope you get sorted soon, don’t forget to report to police too even if you think it’s hopeless. Oh and might not have helped but get yourself a decent dashcam too if you don’t have one.
Hope you’re all well and don’t forget physical injuries can take days to show up and mental health damage can be serious my youngest 16 with ASD won’t fit in the front seat anymore after our accident
