A more pleasant driving experience on a daily basis

On the Seat Leon 5F , the Start & Stop system often intervenes in the least suitable situations: traffic jams, maneuvers, repeated starts or dense urban traffic.
Result: frequent engine cut-outs, abrupt restarts and driving discomfort.

Thanks to this module, the Start & Stop system remains deactivated by default each time the ignition is switched on, without any action required from you. You retain an engine running only when you actually need it.


Two versions depending on the original connector

This module is available in two distinct versions , in order to perfectly adapt to your vehicle's wiring harness:

Version with 6-way connector

Version with 10-way connector

The choice depends on the original configuration of your Start/Stop button. We recommend checking the connector behind the button before ordering to avoid any mistakes.


A definitive and fully reversible solution

Unlike the original button, which does not remember your choice, this module acts directly on the Start & Stop management:

  • The system is automatically disabled at each startup.

  • No error messages on the dashboard

  • No impact on the vehicle's electronics

Do you want to reactivate the Start & Stop? Simply remove the module to return to the original configuration, without leaving any trace or permanent modification.


Protects the mechanics and the battery

The Start & Stop system places significant demands on several mechanical and electrical components.

  • Starter

  • AGM/EFB battery

  • Clutch system

By eliminating unnecessary restarts, you limit premature wear of these components and reduce the risk of costly breakdowns in the long term.


Quick installation – 5 minutes, no coding required

The assembly is simple and accessible, even without special technical skills.

Installation steps

1️⃣ Remove the Start/Stop button panel
Using a plastic pry tool, lift the gear selector boot and then unclip the panel where the Start/Stop button is located. Depending on the version, it may be positioned next to or just in front of the lever.

2️⃣ Plug in the smart module
Disconnect the connector located at the rear of the Start/Stop button, then insert our module between the button and the original wiring harness.
No coding, no modifications: 100% plug and play installation.

3️⃣ Replace the panel
Reattach the panel and make sure it is properly secured.
