Automatic Start/Stop Deactivation Module for Mercedes GLA H247 - 2020 to 2025

Automatic deactivation of Start & Stop on Mercedes GLA H247

The Stop & Start system can quickly become a source of discomfort: repeated engine cut-outs in city traffic, less smooth acceleration, and slight vibrations on automatic versions. These interruptions detract from the usual smoothness and prestige of a Mercedes-Benz.

➡ With our intelligent electronic module, the Start & Stop system automatically deactivates each time the engine is started.
No manipulation is necessary: ​​from the moment of start-up, the engine remains active for a more pleasant and continuous driving experience.

Want to restore the original functionality?
➡ Simply unplug the box. No coding or reprogramming required: installation is completely reversible.

Free delivery – 1-year product warranty

Why install this module on your Mercedes GLA H247?

The Stop & Start system, although economical in theory, can cause:

- Excessive strain on the battery and starter.

- Cut-outs before the turbocharger is fully lubricated.

- Noticeable jerks during restarts.

- Reduced responsiveness in rapid insertions or overtaking maneuvers.

- Unexpected cut-outs during slow maneuvers or on slopes.

➡ Our module improves driving comfort and helps to preserve the mechanics in the long term.
