If anyone even considers this for their E90 you should definitely do this upgrade. The rear looks so much cleaner and more of an updated look.
Got the trunk locally still new from ECS Tuning. Fitment is really good, just need to tweak the bolting position a few times. Had to drill some holes bigger as in the trunk lights.
No bulb out warning no coding needed. once I plugged the new lights in I unplug my battery for 30 seconds and plugged the battery back. As for the trunk lights I did get a new harness from ECS Tuning.
I plan on painting the trunk over the winter.
