Hello~ I have replaced all the interior lights with LED, and I have just got my dome light changed to LED as well. Actually it was pretty easy to take off the front and rear dome after few times of trying.
Front Dome:
1. To take off the front dome ,just simply use a flat head to unclip the little plastic cover above(surround) the rear-view mirror, and then slide off that plastic cover inorder to take off the dome, otherwise the plastic cover would be blocking the way.
2. After sliding off the plastic cover, use a flashlight to look up, you should see two black buttons on both left and right side. Simply push them in with both hands and pull it down at the same time (don't need too much force to pull it down). The whole dome should then be released down.
3. To change the light bulbs, you should see two little buttons thingy on the black cover where the bulbs locate. Just turn the buttons counter-clock wise to unlock the buttons so you can take out the bulbs to replace them. Clock-wise to lock them back. P.S. If the LED bulbs did not light up after the replacement, try to take out the button(with bulb) and put it back in again with the opposite direction u put it in before.
4. Test all the bulbs before pushing the dome back in!
Rear Dome:
1. Use a flat head to pry from the rear(towards the rear window) of the dome. P.S. DO IT SLOWLY! DON'T RUSH!! and then give the dome a little pull at the rear end while prying it down. The dome should come off half of its way (that's what happened to mine, couldn't got it completly off the roof).
2. Just sneaks your hand through the gap to unlock(counter-clock wise) the bulb buttons, and replace the bulbs.
3. AGAIN! if bulbs do not light up, try opposite direcion! AND!!! CHECK THE BULBS BEFORE PUSHING THE DOME BACK IN!!
Hope these info would help anyone who'd like to change the dome lights on their w211! X)
