Across many Internet forums worldwide, this question is asked with no real answer, just guesses that it could be in the ‘footwell’. Well, we have decided to show the location for people who are attempting some DIY work.
This is shown on a 2007 130i.
New footwell module on left (FRM3). Notice the extra ventilation holes. Perhaps BMW suggesting that failures are heat related.
The new module will need coding to the car once fitted. You’ll need a diagnostic machine with coding capabilities to get the module functional.
The footwell module failing is a common issue in many BMW and MINI models, its job is to receive signals from sensors across the vehicle, mainly controlling body aspects such as electric windows, air conditioning, heating, lights (interior and exterior) as well as exterior mirrors.
FRM failure can be caused by jump starting, incorrect charging and water infiltration damaging the sensitive electrics.
What is the common sign that there is an issue with the footwell module?
A common sign that there is an issue with the footwell module is that you will notice issues with one of these elements, such as the lights not turning off or not turning on. You may find you have intermittent issues with your windows not opening or closing.
Obviously, this is a serious issue and can cause road safety issues if taillights are not working as they should. You will notice that the service light is constantly illuminated and if you run a diagnostic check you may see fault codes 397F, A3B4, AC3C1, E72B or E72B.
In some cases, the FRM can be reprogrammed and repairs, in other cases you might need a new one which will need to be programmed to your vehicle. This can either be done at home by yourself if you have a diagnostic machine, or you can bring it to us at Power Developments to investigate and repair.
