BMW Mini Footwell Module Fault - FRM3 Repair

This BMW / Mini footwell module (FRM3) is a commonly failing part that will cause a whole host of ‘body’ control problems on the vehicle such as electric/power windows, AC/heating fans, exterior and interior lights and exterior mirrors.
When the module becomes faulty it will affect operation of these functions. External lights such as the headlights and taillights will remain on all the time and you will find that you will not be able to turn these off. Conversely, the external indicators / turn signals will not work at all, along with main beam and interior lights. Electric / power windows will also intermittently refuse to function as they should. Failure of this critical footwell FRM module is universally widespread across the entire BMW and Mini ranges.
Whilst the footwell module is in fault mode the maintenance or service light will be constantly illuminated. A diagnostic with scan tools will often find that the module fails to achieve communications. Fault codes may still be found in other control modules that will signify a fault with the footwell module.
