Thanks for reply, Yes it was a mobility car and I was charged £60, live and learn.
I think the problem sometimes is that dealers & others are either unaware of the rules or can’t be bothered to seek the required authorisation from Motability, as there’s a short wait whilst they authorise it. Some of us have had this issue with AdBlue top ups. Motability pay for those, as they make it clear that the scheme covers ALL costs other than fuel and cleaning. Even a main VW dealer tried to charge me for an AdBlue top up once and got a bit funny with me when I insisted that I didn’t have to pay. I told them to speak to Motability and they came back 5 minutes later looking very shame faced!
