My saga ends.
So after a few return trips to the dealer who found nothing wrong, I sent video to motability who were as brilliant as ever. The car is finally being returned and I can start again.
Just to add to the list, roof now creaks very loudly, emergency braking still has a vendetta and is still trying to kill me, charger port opens when it feels like it, keyless entry needs a key as door sensors have stopped sensing, charging mostly doesn’t and tells me find another charger or refer to manual, screen still locks up, various functions still turn themselves on and I’m so relieved to see the back of it.
Don’t make the same mistake as I did. Avoid iD.4 and Peter Cooper VW Portsmouth. It’ll only end in tears!
