BMW or MINI dead-armed in Hounslow — windows, lights and indicators out after a jump start or flat battery? That is the footwell module (FRM), and it does not need replacing. We come to you from our Leatherhead base — Hounslow is 11 miles away, typically about 35 minutes — and rebuild the original module at your door in about an hour, coding intact. The m4 corridor, heathrow on the doorstep — and more airport-car-park flat batteries than anywhere else we cover: we know this patch well. More: symptoms checklist · what it costs · dead after a jump start.
The footwell module fails the same way everywhere — the M4 corridor, Heathrow on the doorstep — and more airport-car-park flat batteries than anywhere else we cover. Two or more of these together, especially after a jump start or flat battery, and it is almost certainly the FRM.
The classic: jump leads on a flat battery, engine fires — and windows, indicators and lights are all dead at once. The voltage dip corrupted the FRM's memory. Fully recoverable at your door.
Most commonAll windows quit together after a battery event. Motors and switches are fine — the module lost its configuration. Rebuilt at the car, coding kept.
After battery eventsDipped beam or tail light dark on one side with good bulbs — the FRM drives each circuit individually. Bulb-swapping cannot fix it; rebuilding the module does.
Signature faultPhantom bulb warnings that will not clear and central locking gone erratic complete the picture — the module reporting its own corrupt state.
Same root causeTwo weeks away, a flat battery in long-stay, a rushed jump before the drive home — and the electrics are scrambled by the M4. The classic Heathrow-belt FRM story. We can meet the car where it stands.
The Heathrow patternUsed FRMs carry the donor car's coding and usually refuse to programme. We repair your original instead — nothing to code, nothing to gamble on.
Avoid the trapStrictly mobile, from our Leatherhead base to home, workplace or even the airport car park where the car died.
Call or WhatsApp with your registration, postcode and what happened. The fixed quote comes back in minutes — Hounslow is 11 miles from base, so there are no travel surprises in it.
Driveway, office or street — anywhere across Chiswick, Brentford, Isleworth and the rest of the area. The car does not need to move, which matters when the lights and indicators are down.
The FRM is read and its data rebuilt on the original board, coding intact. Windows, lights both sides, indicators and locking all tested before we pack up.
