How do change headlight bulbs in BMW 2007 328i?

Answer 1

I found that for changing the low beams (outermost bulbs) was easiest because there
is an access panel inside the fender well. You will need to turn the steering wheel to the opposite direction so the tire will be out of the way. You can then use a coin to turn the latches that hold the small panel in place.

Now you can get to the metal clip that holds the u shaped door closed behind the bulb.

(be careful not to drop any tools/parts into the bumper because you will have to take off
3 more screws to fetch the items out of the ground effects...trust me :') )

Once the U shaped door is off, there is a black plug with 3 wires on the bulb. You just have to pull and wiggle until it unplugs. Then there is another metal clip that has to be
slightly pushed to the right to fold down to release the bulb.

Now your ready to put in the new bulb, NOTE: don't touch the glass of the new bulb with
your fingers (the oil will cause the bulb to bust when it gets hot) hold it by the metal.

The tab on the bulb should go up just like the old one came out.

Pop the clip back up, put the plug back on, and close the U shaped door and put it's clip back in place. Now just use your coin to lock the wheel well access panel back in place.

Done. The high beam is the same only you don't have to use the access panel.

BTW the bulb type for both is H7.

Hope this helps.
