Automatic Start/Stop Eliminator Deactivation Module for AUDI A5/S5/RS5 B9 - 2015 to 2024
Direct OEM fit — no cutting
Free US shipping
1-year warranty
30-day easy returns
On the Audi A5, S5, and RS5 B9, the factory Start/Stop system can interrupt the smooth yet dynamic driving experience expected from Audi’s modern coupe and sportback range. Frequent engine shut-offs in traffic, vibrations during restarts, and slight hesitation when pulling away can reduce overall driving fluidity—especially noticeable in daily urban conditions.
Our electronic module permanently solves this issue:
→ The Start/Stop function is automatically deactivated at every ignition start — no button press required.
Our module remembers your latest setting at every startup. Once installed, simply deactivate your vehicle’s Start/Stop functionality, and it will remain disabled until you decide otherwise.
Prefer to return to factory behavior?
→ Simply press your Start/Stop button again. No coding, no permanent modification, and no trace left on the vehicle.

While designed to meet modern efficiency standards, the Start/Stop system can affect throttle response and smooth power delivery, particularly in stop-and-go traffic. It may also place additional strain on the battery and starter while introducing vibrations that detract from the refined yet performance-focused character of the A5 B9 platform.
With this module installed, the engine remains ready at all times, restarts are seamless, and the vehicle delivers a more fluid, responsive, and enjoyable driving experience in everyday use.
