I wouldn't bother with that. It's just not worth it for all that money. I installed the Letronix kit from Germany and I'm pretty happy with them. The installation took 5 minutes and no error codes!!! During the day in bright sun, they aren't very visible, but in the evening, they shine bright and beautiful.
I will snap some pics and send them later. Next I want to change the fog light bulbs. I know you said you don't even turn on your fog lights, but would you know what kind of bulb it uses and how to access it?
I also ordered a full 10 piece BMW OEM LED interior lighting kit to replace all the plain interior bulbs. Along with that I ordered BMW OEM Chrome mirror covers. Can't wait to install those!!!
Not a lot of Mods available for this car compared to the 3 series. For obvious reasons of course!!
