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.

About Ohlins
Ohlins Racing was founded in Sweden in 1976 and has built a global reputation in motorsport suspension engineering across MotoGP, Formula 1, WRC, and road performance applications. The OHL35020-30 is part of Ohlins' Road and Track accessory lineup, engineered to make the transition from factory adaptive suspension to high-performance manually-adjusted coilovers seamless and fault-code-free on BMW G-series and Toyota Supra platforms.
Frequently Asked Questions
Do I need the Ohlins 35020-30 if my BMW G20 does not have the EDC option?No. The OHL35020-30 is only required on BMW G20/G21 3 Series, G22/G23 4 Series, G42 2 Series, G29 Z4, and Toyota Supra A90/J29 vehicles equipped with the factory EDC adaptive suspension option. If your vehicle does not have EDC (factory adaptive shocks), the cancellation kit is not needed for coilover installation.
Will the Ohlins 35020-30 prevent all dash warning lights when removing EDC shocks?Yes. The OHL35020-30 is designed to deactivate the OEM semi-active damper system and prevent fault codes and warning lights in the instrument cluster. It integrates into the factory electrical architecture so that only the EDC function is cancelled without affecting other vehicle control systems.
Does the 35020-30 work with both RWD and xDrive BMW G20/G21?Yes. The OHL35020-30 is compatible with both the rear-wheel drive and xDrive all-wheel drive variants of the BMW G20 and G21 3 Series, as well as the G22 and G23 4 Series in both drivetrain configurations.
Can the Ohlins 35020-30 be used with non-Ohlins coilovers on a G22 BMW?The OHL35020-30 is engineered and marketed by Ohlins as a companion to their Road and Track DFV suspension systems. While the electrical cancellation function may operate with other coilover brands, Ohlins only documents and warrants the kit's function in conjunction with their own suspension products. Consult with the coilover manufacturer or installer regarding compatibility with other brands.
Does the 35020-30 also fit the Toyota Supra GR A90?Yes. The OHL35020-30 is listed for the Toyota Supra A90/J29 platform, which shares BMW's EDC electrical architecture due to the shared BMW-Toyota platform. The same kit is used for both the Supra and the BMW G20/G22/G29 applications.
Is the Ohlins 35020-30 a permanent modification to the BMW?No. The OHL35020-30 is an electrical interface kit, not a physical modification to any vehicle component. It can be removed if the vehicle is returned to factory EDC suspension at any time, restoring the original electrical function of the EDC system.
Does the 35020-30 require any coding or software changes to the BMW DME or iDrive?The OHL35020-30 is designed as a plug-and-play solution that does not require DME coding or iDrive software changes in most applications. Ohlins notes professional installation is recommended for optimal safety and performance. In some markets or with certain factory-equipped packages, additional coding by a BMW specialist may be beneficial to suppress all related chassis control notifications.
Where can I find the installation instructions for the Ohlins 35020-30?Ohlins provides detailed installation instructions with every 35020-30 kit. Mounting instructions are also available directly from Ohlins at ohlins.com under the Road and Track section for BMW 3 Series G20. Professional installation is recommended by Ohlins for optimal safety and performance.
