Universal CAN Filter for MB

Mercedes-Benz Universal CAN Filter – The Ultimate FBS3 & FBS4 Bypass Solution

The M4KEY Universal CAN Filter is a specialized communication module designed to resolve mileage synchronization challenges in Mercedes-Benz vehicles. When an Instrument Cluster (IC) or Electronic Ignition Switch (EIS/EZS) is repaired or replaced, the system automatically attempts to sync the mileage data. Our CAN Filter acts as a professional firewall between these two modules, preventing data overwrites and "------" display errors.

Key Benefits for Professionals:

• Versatile Compatibility: A single filter covers both legacy FBS3 and high-tech FBS4 architectures, reducing your inventory needs.

• Seamless Integration: Once soldered, the filter works silently without interfering with OBD2 diagnostics or other vehicle functions.

• Reliable Hardware: Built with industrial-grade components to withstand high temperatures behind the dashboard or steering column.

• No Coding Required: Hardware-level filtering means you save time on complex software adaptations.

Warning for Professional Use: This device is sold exclusively for use by automotive professionals (auto repair shops, auto locksmiths) and government agencies for lawful purposes. In the event of use for unlawful purposes, all legal liability rests with the user.
