Audi hazard light button — a safety control that responds the first time
This hazard light button for the Audi A3, A4, A6 C5 and Allroad replaces the hazard warning switch listed under part numbers 8D0941509H and 8D0941509K. On these generations, it is a common failure: the button sinks in without activating, remains stuck in position, or no longer illuminates its red triangle. Yet it is a safety control that you must be able to operate without thinking.
A control designed for your Audi A4 and A6 C5
The switch retains the format, texture and backlit triangle of the original part, as well as its console cutout. Two connectors are offered, 9-pin and 10-pin, because the pinout changed during production: simply count the pins on your connector before choosing. Once installed, nothing distinguishes the part from a factory control.
Technology, quality & finish
Reinforced ABS housing, silver internal contacts and a calibrated return spring to restore the original firm click. The indicator is powered by LEDs rather than a filament bulb: no more premature burnout, and constant brightness day and night. The integrated flashing relay complies with the regulatory cadence.
Installation, compatibility & durability
Replacement takes just a few minutes: turn off the ignition, unclip the old control from the console using a plastic spatula, disconnect the connector and plug it into the new part. No coding is required. Compatible with Audi A3, A4, A6 C5 and A6 Allroad depending on the connector: compatibility is based on part numbers 8D0941509H and 8D0941509K, which should be checked against your original part before installation.
