5G0698459 VW & Audi Brake Light Switch - Hall Sensor Master Cylinder

VW & Audi Brake Light Switch – 5G0698459

Restore the safety and communication of your vehicle’s braking system with this premium Brake Light Switch. Unlike older mechanical plunger-style switches located under the dash, the 5G0698459 is a modern Hall Effect sensor typically mounted directly on the brake master cylinder. This advanced sensor monitors fluid pressure and pedal movement to instantly signal your rear brake lights and inform the vehicle's onboard computer (ECU) for systems like cruise control and transmission interlock.

This genuine-quality replacement is essential for resolving common VAG group issues such as brake lights staying on, not illuminating at all, or a "EPC" warning light on the dashboard. Because it is a solid-state sensor, it provides more precise feedback than traditional switches and is more resistant to the mechanical wear of repetitive pedal presses. Replacing a faulty switch is critical not only for road safety but also to ensure your automatic transmission can be shifted out of "Park."

Product Highlights & Features Magnetic Hall Sensor Technology: Non-contact design eliminates internal friction, leading to a significantly longer lifespan compared to older mechanical switches.

Direct Master Cylinder Mount: Specifically designed for vehicles where the switch is located on the brake master cylinder under the hood rather than the pedal assembly.

Critical System Integration: Provides necessary signals for the Cruise Control deactivation, ABS/Traction Control monitoring, and the Shift Interlock Solenoid.

OEM Specification: Matches factory part 5G0698459 exactly for a simple "plug-and-play" installation without the need for harness modifications.

Technical Specifications Part Number: 5G0698459 (Cross Ref: 7.1232)

Alternate Names: Stoplamp Switch, Pressure Sensor, Repair Kit

Location: On Brake Master Cylinder

Connector: 4-Pin Flat Terminal

Installation & Maintenance Tips Confirm Location: Before ordering, verify if your switch is on the master cylinder (under the hood) or the pedal (under the dash). While this part covers most models listed, some early transition years may vary.

No Calibration Required: In most cases, this Hall sensor is "self-calibrating." Once plugged in and secured, the ECU should recognize the signal immediately. If an "EPC" light remains, you may need to clear the fault codes with an OBD-II scanner.

Inspect the Connector: Brake fluid leaks from a failing master cylinder can sometimes travel into the electrical connector. Ensure the harness plug is dry and free of corrosion before installing the new switch.

Safety Check: After installation, have a helper stand behind the vehicle while you press the brake pedal to confirm the lights activate and deactivate promptly.
