I told the chap it was a motability car but he didn’t seem to know anything about the scheme. I got the impression he was new to the job so I didn’t think there was any point in continuing the conversation.
Strangely enough the warning has gone from the dash so I will monitor it over a few days and then call them to see what they advise.
Ive only travelled 4600 miles so I thought it was very premature. So maybe it’s a glitch.
