You jump-started the car — or changed the battery, or put it on charge — and the engine runs fine, but now the windows, indicators and some of the lights are dead, and the dash is full of warnings. Don't panic, and don't buy a module. The voltage dip corrupted your footwell module's (FRM's) memory — a known weakness on BMW 1 & 3 Series, X1, Z4, X5, X6 and MINI R55–R61. We rebuild that data at your door, usually within the hour, and everything comes back as it was.
The giveaway is several systems failing at the same instant — the moment of the jump. Here is the classic set. More detail on each: the full footwell module symptoms checklist.
Every window dead from the moment the engine restarted, one-touch gone. That simultaneous failure is data corruption — four window motors do not break at the same second.
The tell-taleNothing either side, hazards included. On an FRM car both circuits live in the corrupted module — which is why they died together with the windows.
Fails with windowsExterior lights dead (often one side), stuck on, or throwing adaptive-headlight errors. The FRM drives every one of these circuits.
Often one sideBulb failure, general faults — warnings that survive restarts and will not clear, because the module reporting them is the thing that is broken.
Will not clearWill not lock, will not unlock, or only some doors respond since the jump. Same module, same corruption event.
Same root causeThe engine is untouched — it is body electronics that died. That combination (drives fine, everything else broken, straight after a jump) is the FRM signature.
Classic FRM signatureWhat you do in the next hour decides whether this is a quick fix or an expensive detour.
Disconnecting the battery, pulling fuses or trying another jump will not clear corrupted data — and every extra voltage event risks deepening the damage. Leave it be.
A new FRM from BMW is dealer money plus programming. A used one off eBay carries the donor car's coding and often will not programme at all. In most cases your original module is recoverable for a fraction of either.
Call or WhatsApp with your registration, postcode and what happened. Fixed price upfront, then we come to your home, work or the roadside and rebuild the module at the car — about an hour, everything tested before we leave.
Any FRM-equipped BMW or MINI, roughly 2005–2014. If your car is on this list and just came off jump leads with dead electrics, the FRM is the prime suspect.

This is what the job actually looks like — FRM boards opened, read and repaired at component level, not swapped for a costly new unit. These photos are from our own bench.
The dealer route means a new module, programming fees and getting a car with dead lights to them. We come to you, rebuild your original module's data at the car, and test everything — windows, indicators, lights, locking — before we leave. Original coding kept, nothing to programme.
The driveway jump. Flat battery after a holiday, neighbour's jump leads, engine fires — and every window and indicator is dead. FRM data rebuilt at the kerb, all functions back before we leave.
The battery swap. New battery fitted, car now lit up with warnings and no indicators. The swap itself caused the voltage event. Module repaired on the original board, coding untouched.
The recovery bounce. Recovered from a flat at the roadside; lights now out on one side. We meet the car wherever it is and put the FRM right on the spot.
