Footwell Module (FRM) Repair & Recondition
The failure of the Footwell Module (FRM) is recognised as an all too common problem for several BMW and Mini Cooper models. In layman’s terms the FRM is a ‘body control unit’ which is responsible for all the exterior and interior lights, indicators, windscreen wipers, sideview mirrors and electric windows.
Various sensors which are situated in the body of the car send signals to the footwell module. So when the module fails it can cause many systems to malfunction.
What Are The Common Symptoms of FRM Failure?
You will notice several common symptoms when the FRM fails:
- Headlights stay on all the time
- Indicators don’t work
- Tail lights stay on and don’t switch off
- Hazard lights don’t function
- The headlights bright main beam doesn’t turn on
- Interior lights don’t work
- Electric/power windows don’t work or can be opened but not closed
- Aircondtioner fan doesn’t function
- The service light remains on
- No communications with FRM unit
What Causes the FRM to Fail?
The primary reason which causes the FRM to fail is by jump-starting the battery. This doesn’t mean the incorrect procedure was followed but a voltage spike occurs which damages the e-prom on the footwell module. Failure can also be caused by disconnecting the battery.
The FRM will sometimes stop working immediately or the damage will only show up when a diagnostic machine is connected.
What is The Cost to Replace the FRM?
There are two options available – either to replace the FRM or to recondition the existing unit.
- 1. Unfortunately, the cost of replacing the FRM with a new unit is significant. As of May 2022, the FRM replacement is R7800 plus R440 installation fee. Then the unit needs to be coded to the vehicle which is a further R1200
Total = R9440 (ex Vat).
- 2. Repair and recondition your existing FRM unit
Total = R3200 (ex Vat).
NB: We provide a 1 year warranty on workmanship as long as there isn’t another voltage spike.
To avoid the footwell module from failing it is wise to have your battery tested to ensure it is in optimal condition.
We use the BMW battery diagnostics tool (ISTA) to check the battery energy levels and to check the alternator is functioning. We assess whether the vehicle has current draw.
