BMW X5 E70 headlight service: bulbs and lens
How do you replace the xenon bulb (D1S) on an X5 E70?
The bulb is a D1S-type xenon bulb. The wiring is disconnected before removing the bulb. Some people change it from above in the tight space without removing wheels, while others had to remove the front wheel and the inner fender liner, so the disassembly needed varies.
How do you replace the fog light bulb on an X5 E70?
The fog light bulb has an H11 base. Remove the small grille or cover in the bumper below the fog light so your hand fits in. The change works without tools in about 15 minutes.
How do you remove the headlight lens on an X5 E70?
The lens comes off by heating the adhesive with a heat gun. The job is slow, about 45 minutes, and the corners of the lens can break. Replacing the lens is a laborious job.
Can a cloudy headlight lens be polished?
Sanding can restore the lens to nearly new, but not completely new, and the result does not necessarily last long. A new lens scratches easily, so a coating was recommended.
