Headlight diagnosis

Morning guys, I just got my first BMW last month through BMW dealership as CPO

When I am driving at night, I noticed my left headlight angel is lower than the right one.

I got a battery recall appointment next week, should I ask them to do the headlight diagnosis for me (its $145/hour) + the repair fee
It's not cover under my CPO warranty

Or any auto shop can repair it? (If anyone can recommend a shop in Vancouver would be greatly appreciated)

Thanks

It is designed to be slightly lower as to not blind oncoming drivers.

No, most cars with HIDs have it this way.

You can simply adjust it up if you want with a TORX screwdriver and a white wall.

Brian! - Do you have the adaptive headlight option? If you have a light switch with a "3" to the left of the 0 position, you do. I've raised my left headlight a little so that they are almost even, but want to caution you that if you ever run your lights in position 2 (non adaptive), that left light may be way too high. If you do any adjusting, take this into account and find the happy place where the left beam isn't blinding in the non adaptive mode. Adjusting them is easy.

Nah, I don't thin I have the adaptive headlight option as its only available for 2012 models and up

People said the left headlight angel is lower its designed to prevent blinding the incoming car with your headlight during night time

So, I guess I will just leave it like that

Thanks everyone

If you have xenons, the left one is not actually supposed to be lower. It just appears lower but that is because the cutoff pattern eliminates more light from the left half of both headlight beams, than from the right hand side of the beam. Basically a cover flips over the part of the light (both headlights) to shield oncoming traffic, you don't actually aim the headlight lower, big misconception. Both headlights should be the same height, the cutoff cover does all the work of making it appear the left side of EACH beam is lower.

If you pull up against the garage or wall, you will see the beams look like this...

___/ ___/

that angled step is where the right hand side of both beams is allowed to shine higher. The cutoff stops the light shining that high on the left side of each beam. If you then backed up and let your lights shine down the road, the left side of each beam should be low, while the right side of each beam should illuminate higher and against the shoulder where signs are.

If you flick the high beams on and off, you will see how the cutoff flips out of the way and allows the full beam to shine. This is what is meant by the left being lower, not that the left light should actually be aimed lower. Common misconception that many do not get.

Do a search for aiming xenons. Here's a link to an aiming procedure... http://www.danielsternlighting.com/tech/aim/aim.html You can do this yourself with a screwdriver.

These are a good step alignment... the bottom of the step for both lights is level....






If the bottom of both steps is not level, make them level.

Again the step is what makes light not hit oncoming traffic, not the actual headlight being aimed lower.
