BMW & MINI FRM Module Repair Guide
The FRM3 footwell module controls lighting, windows, mirrors, and central locking on most 2007–2014 BMW and MINI vehicles. When it fails, half the car stops working — but you don't need a new virgin module from BMW.

Symptoms of a failed FRM
- • All windows dead — no auto-up, no auto-down
- • Headlights, fogs, or turn signals not working
- • Interior lights stuck on or completely dead
- • Central locking inoperative from key or door
- • Car won't go into the dealer's coding session
- • Battery drain after sitting overnight
Why the FRM3 fails
The FRM3 stores its boot loader in an EEPROM that gets corrupted when battery voltage dips during coding, jump starts, or a weak battery. Once the EEPROM is corrupted the module is locked — BMW's position is that it must be replaced with a new VIN-coded unit (~$900–$1,400 plus programming).
Component-level repair recovers the EEPROM, restores the boot loader, and preserves the original VIN, mileage, and personalization data — so the car runs exactly as it did before, with no dealer coding required.
Vehicles affected
- • 2007–2013 BMW 1 Series (E81 / E82 / E87 / E88)
- • 2006–2013 BMW 3 Series (E90 / E91 / E92 / E93)
- • 2008–2014 BMW X1 (E84)
- • 2007–2013 BMW X5 (E70) and X6 (E71)
- • 2008–2015 MINI Cooper / Clubman / Countryman (R55–R61)
How TMW Repairs fixes it
- You ship the FRM3 to our facility (it's under the left footwell trim — about 15 minutes to remove).
- We recover the EEPROM, rewrite the boot loader, and repair any failed driver ICs.
- The module is bench-tested with simulated CAN traffic before it ships back.
- You plug it back in — original VIN, original mileage, no dealer coding required.
Cost & turnaround
- • 2–3 business day turnaround once we receive it
- • 1-year warranty on the repair
- • ~70% cheaper than a virgin BMW replacement + coding

Questions buyers ask before sending it in
Why does the FRM3 fail?
The boot loader EEPROM gets corrupted when battery voltage dips during coding sessions, jump starts, or with a weak battery. Once corrupted the module is locked and refuses to boot.
Can BMW reset it?
No. BMW's official fix is a new VIN-coded virgin module at roughly $900–$1,400 plus dealer programming. Component-level repair recovers the existing EEPROM and saves the original module.
Which vehicles have an FRM3?
Most 2007–2013 BMW 1, 3, X1, X5, and X6 series, plus 2008–2015 MINI Cooper, Clubman, and Countryman (R55–R61).
Will I lose my VIN, mileage, or coding?
No. The original VIN, mileage, personalization, and coding all stay on the module — that's why no dealer programming is required after the repair.
How long is the turnaround?
2–3 business days of bench time, plus return shipping. 1-year warranty on every FRM repair.
