Mine's a 67 plate. I'll inquire about about a firmware update when the car goes in for a service. No doubt the garage will have no idea about the paddle issue, and won't be able to guarantee that the issue will be sorted. Considering I hear the updates are quite expensive, it's a bit of a gamble!So when I initially checked I only did it comfort mode.
After reading your post I gave it a try in sport mode this morning and mine also hangs on to the gears.
Is yours a 68 or 19 plate by any chance?
Mine is a 68 and it also has the new HUD firmware and configurable ambient lighting. My guess is if you have a 68 or newer with these features, then it appears they put the new gearbox firmware in too. 👍
Judging by another thread, it's almost guaranteed in a 19 plate.
