01
What do you notice?
Turn signals and power windows do not respond, lights stay on or the footwell module cannot be reached by diagnostics. This is often noticed after a dead battery or battery replacement.

BRIEFLY EXPLAINED · FROM FAULT TO REPAIR
Understand what is being repaired.
02
What might be damaged?
Internal memory data in the FRM3 can become corrupted. A single failed lighting output, however, may be a short-circuit lockout. Data errors, lockouts and hardware defects require different solutions.
03
How do we fix it?
We identify the FRM variant and assess the data condition. For a suitable standard fault, we restore the module data. Hardware or moisture damage is assessed separately.
04
How is it checked?
Data access and module communication are checked and documented. After installation, lights, turn signals and power windows are tested on the vehicle; required initializations depend on the version.
For a lasting result.
The battery and vehicle voltage must be stable. With a short-circuit lockout, the defective load or wiring must be repaired before the output is re-enabled.
01 / SERVICE
What we offer you.
What is a footwell module?
Depending on the vehicle, the FRM controls lighting, turn signals and power windows, among other functions. If the module fails, several seemingly unrelated functions may be affected at once. You will find the FRM version on the label.
Repair is not always the same as a reset
An unresponsive FRM3 with corrupted memory data is a different case from a single blocked lighting output. We distinguish data errors, output lockouts and hardware defects, and choose the appropriate procedure.
149 € with a clearly described scope
The price applies to the agreed standard repair on a suitable original module, including VAT and standard return shipping. Corrosion, destroyed components, replacement modules and additional coding are quoted separately if needed. Express return shipping is available by arrangement for an additional 20 €.
Original module instead of a premature parts purchase
If the original data is successfully restored, the existing module can continue to be used. A used FRM, however, must match the vehicle version and may require programming or coding. Please check replacement parts before buying.
FAULT CODES · DTC · OBD
Common fault codes and their meanings.
These codes are frequently read during inquiries about this system. A DTC identifies the detected deviation – the actual cause emerges only from the vehicle, software version, fault status and measured values.
Possible indications from other control units
- A3B4
- Missing or incorrect lamp-status message
- A3C1
- Indication of missing FRM communication / network management, depending on the diagnostic tool
These messages are clues, not automatic confirmation of repair suitability. A single lighting output may also have a short-circuit lockout; the external fault must be repaired first.
BMW E SERIES · MINI R SERIES
Typical model series with suitable FRM variants.
| Vehicle | Model series | Identification |
|---|---|---|
| BMW 1 Series and 3 Series | E81, E82, E87, E88 · E90, E91, E92, E93 | Check FRM version and hardware using the label |
| BMW X and Z4 | X1 E84 · X5 E70 · X6 E71 · Z4 E89 | Equipment and production version are decisive |
| MINI | R55, R56, R57, R58, R59, R60, R61 | Only suitable footwell module versions |

QUESTIONS & ANSWERS
Well informed in advance.
Can the FRM fail after a battery replacement?
Yes. Low voltage or an interrupted internal process can be associated with a data error. We therefore check the module's condition and recommend checking the battery and electrical system before reinstallation.
Only one light is not working. Is the FRM defective?
Not necessarily. The lamp, wiring or a blocked output may also be responsible. Blanket replacement or a data reset does not fix an external short circuit.
Is coding needed afterward?
After restoring the existing original data, complete recoding is often unnecessary. Replacement modules, changed data or a different version may require additional work.
Where is the FRM located?
In many of the listed BMW and MINI versions, it is in the driver's footwell behind the side trim. The exact removal procedure depends on the vehicle and should be carried out professionally.
What should I send before shipping?
A photo of the entire label, the model, model year and diagnostic report. Also describe whether the problem occurred after low voltage, jump-starting or diagnostic work.
