shame.
I've added it to my list of parts.

I just fitted all LEDs to my interior.

Wondering if I'll have issues like you experienced.

Did you sorted out your fibre optic light strip in the left rear door?
I have same issues:
first, light strip in the rear door doesn't work
second, sometimes exterior led light in door handle plays around.. more likely if you unlock car by keyfob it glows only rear handles led lights, but few times I have seen all 4 was working at same time. Anyone has a clue? if I scan car with original ross-tech diagnostic cable it nothing pop up, same with one door handle button on top not working and heating sensor underneath, but other 3 it's fine, but again after scanning car with latest software nothing pops up . Thanks

Sometimes it's the fibre optic controller that goes duff not the strip itself and you can change it by taking the door card off its attached to the back of the door card. I've got plenty of them I changed my interior not long back so I have 3 or 4 door cards lying around complete ill have a look later for you. What door was it ?
