Home › FRM Footwell Module
If your BMW’s headlights, tail lights, turn signals, windows, or mirrors all stopped working at once — often right after a battery change or jump start — the footwell module (FRM) has most likely failed. We diagnose it, replace or recover it, and program and VIN-code it on-site, so the car doesn’t need a tow to the dealer.
The FRM controls exterior and interior lighting, power windows, and mirrors. When its memory corrupts, everything it controls goes down together — which is why a failed FRM looks like a dozen separate electrical problems.
Headlights or parking lights stuck on or completely off, no turn signals, brake or tail lights out, interior lights dead.
Power windows won’t move, mirrors won’t adjust or fold, convertible top functions blocked.
Typically right after a battery replacement, a jump start, a deeply discharged battery, or an interrupted programming session.
FRM failure is most common on E-Series cars built roughly 2007–2013. Send your VIN and the symptoms and we confirm whether it is the FRM before anything is replaced.
| Model | Chassis | Notes |
|---|---|---|
| 3 Series | E90, E91, E92, E93 | The classic case — most common |
| 1 Series | E81, E82, E87, E88 | Same module family |
| X1 / X5 / X6 | E84, E70, E71 | Later production years |
| Z4 | E89 | Supported |
| MINI | R55–R60 | Same failure pattern |
Before you buy a module: a used FRM from another car will not work until it is programmed and coded to your VIN. Confirm the fault first — the same symptoms can come from a blown fuse or low battery voltage, which costs far less to fix.
Text your 17-digit VIN and what the car is doing to 619-500-3096, or use the booking form.
You get exact pricing up front — mobile service within San Diego County included.
We confirm the FRM is the fault — not a fuse, wiring, or battery issue — at your location.
The module is replaced or recovered, programmed, and VIN-coded, then every light, window, and mirror is tested.
FRM stands for footwell module (Fußraummodul). It is the control unit that runs exterior and interior lighting, power windows, and mirrors on many E-Series BMWs and MINIs.
The module’s memory can corrupt when voltage drops or spikes — during a battery swap, a jump start, or a deeply discharged battery. The hardware is often fine; the data is not.
A failed FRM usually takes out lights, windows, and mirrors together and stops communicating with diagnostic tools. A fuse or wiring fault normally affects one function. On-site diagnostics confirms which it is.
It is not safe or legal to drive without working brake lights, turn signals, or headlights. Because SDBC is mobile, the car can be fixed where it sits.
You can physically swap it, but a used module carries another car’s VIN and configuration and will not work correctly until it is programmed and coded to your vehicle.
Keep the battery healthy, connect a stable power supply during any battery work or programming, follow BMW’s jump-start points, and have a new battery registered.
SDBC handles coding, programming, diagnostics, and electrical/module faults. We don’t do mechanical repair or parts replacement such as brakes, suspension, or engine work.
