Start Stop Canceller Switch For Audi A3 S3 RS3 8V 2013-2020

Keep your Audi’s engine running smoothly during short stoppages with this Start Stop Canceller Switch, engineered specifically for the Audi A3, S3, and RS3 (8V model years 2013–2020). Frequently forced restarts from the factory start-stop system can accelerate engine wear and shorten battery life. This plug-and-play module overrides those defaults, permanently disabling the automatic cutoff so your vehicle cruises without interruption. Designed as a direct replacement for your existing “A OFF” button, it installs cleanly behind the console panel using a dedicated wiring harness that connects seamlessly to the factory socket. Once set up, the button’s LED illuminates red to confirm the system remains off by default, eliminating repetitive daily adjustments while preserving your OEM interior aesthetics.

Benefits & Practical Tips

• Reduces premature battery degradation by bypassing unnecessary ignition cycles in heavy city traffic.
• Install quickly by removing the center console trim and plugging the supplied harness directly into the factory socket—no drilling or splicing required.
• Press the dedicated button briefly when you need temporary start-stop functionality, such as during an automated car wash, then release to return to the default-off state.

Warnings & Reminders

This module requires your vehicle to already feature a physical “A OFF” button near the center console. If your factory setup lacks this switch, the installer cannot accommodate your dashboard layout. Always verify compatibility with your specific trim level before purchase, as certain sport packages route start-stop signals differently.
