Well, they fiddled around for a few hours and updated it... Seems to have done the trick. No-one seems to know what caused it unfortunately.
More KUDOS for TJ Vickers in Telford as well, great customer service, friendly, fair and honest.
I had a 1.4 Pop 500 as a courtesy car which is pretty nippy, great car for what it is, but it really did make me appreciate the Bravo, because the interior was 'not as good.'
