I will try it tomorrow, but have never had an issue with it other than a low fob battery on the dash early this year, to which I replaced said battery and no issues since.
...everything is bloody frustrating until you solve it...then its not....it will turn out to be a simple fix for sure...good luck and let us know how you get on.
Tried this today. As i suspected, no change at all. It’s def not the battery, not the fob and not the fuses. Looks like it’s a mystery for the dealer to solve
