Long story short, new panel £260, dealer not interested and not covered by extended warranty. So I did some searching and found quite a few in the US have managed to snap these tabs off and there are a few fix options around.
I still had one of the tabs so I stuck this back on with Q-Bond, a super strong super glue, as recommended on another forum, result its brilliant stuff and the tab stuck straight back on and seems to be really strong.
Now to the front tab, I made a tab from ali and stuck the L shaped tab on with JB Weld. Stuck brilliantly. Put the panel back on this morning and it fits better than it did before and if the reports from other forums is to be believed, the fix is stronger than the original offering from BMW. Result
