HID Headlight Disassembling and Low/High Beam Adjustment

I have been having some intermittent issue with one of the factory HID Headlights (D2S type) on my car that seems to require some troubleshooting beyond swapping the bulbs around. Thus I am thinking about disassembling both units to swap some of the components around, unplug some of the connectors, clean them and check for any issue like corrosion or physical damage to wires or other components.

This is happening on a 2001 330i which has HID low-beam and regular halogen high-beam. How will taking the headlights assemblies apart affect the beam adjustment of both low and high beam? If I am not mistaken the low-beam (HID) is self leveling, right? However, does it need any type of adjustment?

It is self leveling if the car is equipped with the sensors (on the front right control arm and one of the rear control arms)

If you already swapped bulbs around swap around the ballasts. Take a look at the connector that goes to the bulbs. Maybe it is melted which commonly happens. If it is melted you will need a new ignitor. You can use my vid below to help you take the light apart etc
