🛠 We offer fast, reliable BMW FRM3 repairs—no coding needed, lifetime warranty included
The BMW FRM3 (Footwell Module) controls key electrical systems such as lighting, windows, indicators, and interior controls. When it fails, these systems can stop working completely. This often happens after a flat battery or jump-start, and is usually accompanied by fault codes like 30BA, 30BB, or 9315.
At ECU Fix, we specialise in repairing BMW FRM3 modules, restoring full function quickly—without replacing the unit or requiring any coding.
🔍 What Is the BMW FRM3?
The FRM3 module is an advanced electronic controller located in the footwell area of many BMW and Mini models. It manages lighting, window lift motors, mirror adjustment, and more. When it develops an internal fault, these features stop responding.
Common fault codes include:
- 30BA – FRM Internal Fault
- 30BB – FRM Supply Voltage Fault
- 9315 – Internal Communication Error
These codes are typically caused by software corruption or voltage-related component failure inside the module—not wiring or sensors.
⚠️ Symptoms of BMW FRM3 Failure
When the BMW FRM3 fails, you may notice:
- No headlights, indicators, or brake lights
- Electric windows not responding
- Mirrors or interior lights failing
- Diagnostic tools can’t access or read the FRM module
- One or more of the above after a battery drain or jump-start
If your scan tool shows 30BA, 30BB, or 9315, the FRM3 module is almost certainly the issue—and can often be repaired.
