Setup, Compatibility & Care
Compatibility: This switch is compatible with a wide range of vehicles including various VW Golf, Transporter, Polo, Passat, Jetta, and Derby models, as well as Audi 100 and 80 series, Skoda 100 Limousine, and several Porsche 911, 914, and 912 variants. Always verify that your vehicle uses a hydraulic brake light switch with an M10x1 thread and requires a 22mm spanner size.
Setup: Installation requires accessing the brake light switch port on your vehicle's hydraulic brake system. Ensure the vehicle is parked on a level surface with the parking brake engaged. Disconnect the battery before commencing work. Carefully unscrew the old switch using a 22mm spanner and disconnect the electrical connector. Screw in the new Hella switch, ensuring it is hand-tightened initially, then secured with the spanner to the specified torque (consult vehicle manual if available). Reconnect the electrical connector. After installation, reconnect the battery and test the brake lights by pressing the brake pedal. Bleeding the brake system may be necessary after installation to remove any air introduced.
Care: This switch is a sealed unit and generally requires no user maintenance. Keep the area around the switch clean. Avoid exposing the electrical connector to excessive moisture or corrosive substances. Regular checks of brake light functionality are recommended.
