A BMW E53 light control module replacement may be necessary if the turn signals or headlights are malfunctioning in your 2000-2006 X5.

The light control module, also known as the "LCM", is an electronic circuit board that controls headlight and turn signal functionality. It replaced the use of relays in the late 1980's by combining all of the functions into one module. The LCM in 2000-2005 X5 vehicles is located in the passenger side footwell.
The LCM is infamous for failing. The classic symptoms of a defective LCM are; one or more headlights or turn signals staying on after the vehicle is shut off, turn signal malfunctions (not blinking correctly) and headlight high beams inoperable.
There is a known issue with 2000-2006 X5 sunroof drains backing up allowing water to infiltrate the LCM shorting them out. If you find moisture and/or rusty frame parts while removing the LCM, you will need to clean the sunroof drains to prevent damage to the replacement unit.
Replacing the X5 LCM is a relatively easy job for the home mechanic and can save a very expensive trip to the dealership. In order to properly remove the LCM from the vehicle, the glove box must be removed. There is unfortunately not enough room to navigate the LCM out of the footwell with the glove box in place. The BMW Repair Guide strongly recommends replacing a failed LCM with a new unit - avoid purchasing used ones. We give detailed step-by-step instructions on removing the LCM from your 2000-2005 X5 below.
