The electrical family is the R56 one: the FRM3 footwell module runs the lights and windows and fails the same way when voltage drops during a battery change or a jump start. Lights stuck on and windows dead at the same moment point at the module, not at the switches.

Modules that fail on this one
- FRM (footwell module)The footwell module on E-series BMWs, Mini R5x and the F01/F10/F25 family — exterior lights, front windows, mirrors — and the module that can corrupt itself when voltage drops.
Work this generation comes in for
- Diagnostics & Electrical TroubleshootingComplex, intermittent and non-standard faults in electronic systems and the digital data buses (CAN, LIN, FlexRay, MOST), and in the wiring itself: parasitic drains, water damage, chewed or brittle harnesses.
- FRM3 Footwell Module RepairRepair of the FRM3 footwell module — the box behind dead lights, stuck windows and unresponsive signals on E-Series BMW and Mini. $200, comes back plug & play.
- Control Unit Replacement & AdaptationFull-cycle adaptation and synchronization of both new and used control units, component protection removal, and configuration to the specific car.
