Ohlins 19-21 BMW 3/4-Series (G2X) RWD/xDrive EDC Cancellation Kit

No Fault Codes, No Compromises: Ohlins EDC Cancellation Kit for BMW G20 G22 G29 G42

The Ohlins 35020-30 EDC Cancellation Kit is a required companion when installing any manually adjustable aftermarket suspension on a BMW 3 Series G20/G21, 4 Series G22/G23, Z4 G29, or 2 Series G42 equipped with factory EDC (Electronic Damper Control) adaptive suspension. The OHL35020-30 deactivates the OEM semi-active damper system and prevents fault codes, warning lights, and instrument cluster errors that appear when the factory EDC shocks are disconnected or removed. The kit integrates directly into the vehicle's existing electrical architecture, ensuring no disruption to other vehicle systems. Ohlins provides detailed installation instructions with every kit and professional installation is recommended.
