What are the instructions for adjusting the headlights and fog lights on BMW 325i?

All covered models have halogen bulbs for the high beam. On earlier models, the low-beam bulb is also a halogen type. On later models, the low-beam bulb is a Xenon type, also called High Intensity Discharge (HID). Some models have an electrically operated headlight beam adjustment system which is controlled through the switch in the instrument panel. On these models, ensure that the switch is set to the off position before adjusting the headlight aim. Each headlight has an adjusting screw for vertical adjustment. The headlight vertical adjustment screw is accessed from behind the headlight, while the horizontal screw (If equipped) is accessed through a hole In the Inner fender. There is no horizontal adjustment screw. There are several ways to adjust the headlights. The simplest method requires an open area with a blank wall and a level floor. Position masking tape vertically on the wall in reference to the vehicle centerline and the centerlines of both headlights. Position a horizontal tape line in reference to the centerline of the headlights. It might be easier to position the tape on the wall with the vehicle parked only a few inches away. Adjustment should be made with the vehicle parked 25 feet from the wall, sitting level, the gas tank full, and no unusually heavy load in the vehicle. The high-intensity zone should be vertically centered with the exact center about three inches below the horizontal line. Have the headlights adjusted by a qualified technician at the earliest opportunity. For fog lights, park the vehicle 25 feet from the wall. Tape a horizontal line on the wall that represents the height of the fog lights and tape another line four inches below that line. Using the adjusting screw on each fog light, adjust the pattern on the wall so that the top of the fog light beam meets the lower line on the wall. The adjustment screw on F-series chassis models is accessed through a small hole in the fog light fascia in the bumper cover.

BMW 325i Headlight

The BMW 325i Headlight is designed to shine through darkness and fog, illuminating the road ahead and making drivers more visible to others. Over the course of production, BMW made available composite housings integrating reflector or projector optics, giving every 325i a more sophisticated nose and improved beam control. The early halogen Headlight units contained a tungsten filament that was surrounded by halogen gas. It produced quite a bright light but had a shorter life. Later models introduced xenon, also called HID, where an electric arc excites xenon gas to create a whiter beam. Upmarket trims adopted LED Headlight arrays that sip power and last for years. The presence of halo rings around the main lamp imparts a look that many enthusiasts will recognize. Further, projector style assemblies focus light through a lens for a sharp cutoff that minimizes glare. All 325i models, regardless of technology, feature high and low beam functions housed in an aerodynamic shell that minimizes wind drag. When the Headlight in your BMW 325i get cloudy or start flickering, they will need a new Headlight assembly. Depending on whether you need halogen, xenon, or LED, you can get back the confidence at night customers expect. Regularly cleaning the BMW Headlights using gentle abrasives like toothpaste helps keep them bright.
