Helpful Information
This guide aims to provide 'general' information about this part type, such as common issues that we've encountered and tips on determining fitment compatibility.
BMWs are prone to electrical issues. Thankfully, most issues are easy to diagnoses due to the electronics having distinct functions and clear fault codes. If you have an undiagnosed electrical issue we highly recommend consulting an independent BMW specialist mechanic. Once you know what the issue is we can check our stock for a replacement component.
Each control unit/module performs a unique function. If you have an undiagnosed electrical problem with your BMW we recommend taking it to an independent specialist or consulting the BMW forums.
Cameras, battery cables, park sensors and LED module
Finding a compatible camera, battery cable, PDC/PMA sensor or LED module for your BMW is simple because these items are uncoded. All we need is your vehicle’s VIN.
Control units and modules
Second-hand control units/modules are more complicated to match, as they’re already coded and have different firmware versions installed on them. This means that matching the genuine BMW number from the catalogue won’t suffice.
The best method for matching up a second-hand control unit/module is to get information directly off the physical unit. In most cases, matching up the BMW part number physically on the unit will ensure there is no/minimal coding required.
Sometimes modules with more recent firmware version will work in older vehicle, but this isn’t a hard rule.
Please note that the reason for BMW dealerships only needing your VIN to find a match, is that brand-new control unit/modules come uncoded and with the latest firmware version. This means that they can easily be coded with a basic scan tool.
Within each generation (such as F-generation BMWs) there is high-interchangeability of electronics. For instance, the control unit for the reversing camera system in the F20 1 Series is also used in F25 X3. In most instance as long as the firmware is matched the items can be coded to the car. This is not a hard rule for every control unit/module, so please contact our team to assist you with finding a compatible replacement.
