Adjusting The Main-Beam Assistant

WARNING: This page does not describe the selected car, but rather 46 other vehicles, including the 2008 BMW M5, 2008 BMW 650i, 2007 BMW Z4, 2007 BMW M6, and 2007 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.

The main-beam assistant can require adjustment only in the following situations:

  1. Windscreen or interior mirror has been exchanged, and windscreen and interior mirror are in correct installation position, see VISUAL INSPECTION OF MAIN-BEAM ASSISTANT  .
  2. The main-beam assistant is unable to self-adjust despite lengthy journey at night of a straight road with easily recognisable road markings (straight ahead for a distance of approx. 50 km: a relatively straight stretch accelerates the directional orientation).
  3. Resetting the main-beam assistant to basic setting has not improved its function.
  4. All system tolerances are considered (see above).
Only if these conditions are satisfied may the main-beam assistant be reset with the special tool.

IMPORTANT: A malfunction will result if the main-beam assistant is not correctly adjusted.  The main-beam assistant is correctly set in the factory and only has to be reset in the workshop is isolated cases.
IMPORTANT: Only reset the main-beam assistant as described in the instructions using the special tool.  This work must only be performed in justified exceptional cases.

The illustration shows the setting of the main-beam assistant using alignment cords and lamp. See procedure below for a detailed description.

The procedure for adjusting the main-beam assistant is as follows:

  1. Place the vehicle in a darkened room. Make sure that there are no light sources or reflective objects in front of the vehicle.
  2. Switch on the ignition.
  3. Attach one of the alignment cords to each door mirror.
  4. Bring the ends of the cords to the front of the car.
  5. Bring the two cords together. There is a mark on each of the alignment cords. The point at which the two marks come together coincides with the centreline of the car.
  6. Place a lamp (e.g. BMW hand-held lamp) in the notch at the end of the alignment cords. Holding the lamp above the point at which the two marks come together, direct the beam of light toward the image sensor.
  7. Perform test procedure (test module) "Check FLA" as described in the instructions.
Under these conditions, the main-beam assistant is recalibrated. That means: The new values are stored in the main-beam assistant.
