In this video I'll be showing you where is located and how to replace the BCM ( Body Control Module ) on a BMW E70 X5. The BCM in my truck went bad so the central locking stopped working, the rear windows, the windshield wipers, the fuel gauge, the trunk latch and the glove box all stopped working. After replacing it with a used module from ebay everything is back to normal and functioning as it should.
Also if you are replacing the module with a used one it is best to find one that came out of the same model vehicle and ideally with the same factory options. For example if I your truck don't have parking sensors and you install BCM from a vehicle that did have them as option, now you will get an error message every time you go in reverse. The cure for that will be to find someone with a scan tool capable of turning these features off in the bcm.
