How do you remove the orange sidemarkers on a 2003 330ci?

Answer 1

if you are referring to the sidemarkers that are on the side of the front fendors, they are spring loaded on one side of the light housing. simple push it towards the front (or rear if the spring is on the other side) and it should move. Once you've moved it, the other end should be able to slide out. Then, disconnect the bulb from the sidemarker light housing.

hope that helps...

Answer 2

Here are instructions on removing the markers. Be aware, you will most likely break them when removing - the reflector plastic is pretty brittle.
