BMW Body Control Module (FRM) Repair

Fixing Electrical Chaos After a Collision

The **BMW Body Control Module (FRM/Footwell Module)** is the brain behind many of your vehicle's low-voltage systems, including lights, windows, mirrors, and door locks. After a collision, even a minor one, or from water intrusion, this module can become damaged or corrupted. This can lead to a confusing array of electrical issues that can be difficult to diagnose. Our mobile service in London provides a safe, accurate, on-site solution to identify and, where possible, repair these complex electrical faults.

Our Specialist On-Site Diagnostics Process:

We provide a crucial first step in the repair process by bringing our expertise directly to your car's location.

• Advanced Diagnostic Scan: We use specialised OEM-level software to connect to the FRM and other control units, which allows us to read deep-level fault codes that a standard scanner cannot.
• Physical & Water Damage Inspection: We perform a thorough visual inspection of the module and its surrounding area in the footwell, looking for signs of physical impact, damaged wiring, or water intrusion.
• Data Corruption Repair: In many cases, an electrical event from a collision can corrupt the FRM's internal data. We can often perform a professional data reset or repair, restoring the module's functionality without the need for a costly replacement.
• Expert Report: We will provide a comprehensive report detailing our findings and an honest recommendation. If the FRM unit is physically damaged beyond repair, it will need to be replaced and coded at a specialist workshop. Our mobile service provides the accurate diagnosis you need to make an informed decision.

Safety Note: Your safety is our top priority. A malfunctioning FRM can affect critical lights, making your vehicle unsafe to drive. Our service ensures a professional diagnosis from a qualified technician, giving you peace of mind.
