Seat Leon KL - Memory module

Keep Your Seat Leon Settings Just the Way You Like Them

This plug and play memory module ensures that your Seat Leon (or Cupra Leon) settings are always preserved, providing a seamless driving experience every time you start your vehicle. With one purchase and one device, you will get memory for (almost) everything. 

Key features:

• Drive Mode Memory: Retain your last set drive mode, a unique feature that sets our module apart globally.
  
• Start-Stop Memory: Ensure the start-stop system stays off (even when switching to Eco mode). Our module automatically disables it for you.
• Lane Assist Memory: Retain your previously set lane assist state, if it was disabled through infotainment screen.
  
• Front Assist Memory: Retain your previously set front assist state, if it was disabled through infotainment screen.
• Front Assist Advance Warning Memory: Upon request, we can add an optional memory function for the Advance Warning system, allowing it to retain its 'off' state if previously disabled.

Smart Memory Management

Our module keeps the memory only when adjustments are made through the infotainment touch screen. Changes made using the steering wheel controls are ignored, allowing for one-time activations of lane-assist or front-assist, without changing the last set memory. This setting can be customized upon request to apply memory universally across both infotainment and steering wheel controls.

No software modification needed

The module connects directly to the onboard network and operates only while plugged in, eliminating the need for any ECU flashing or coding. It avoids the associated risks and remains undetectable by standard diagnostic tools, even retrospectively.

Quality Wiring Harness

Our wiring harness plugs directly into the car gateway, functioning as both a splitter and an extension. It is crucial to use a high-quality harness for this purpose. Built from OEM components, our harness features TE Connectivity terminals and connector housings, just like original VW harness. All CAN bus lines are routed as twisted pairs, and every line has the same cross-sectional area as the original one. This ensures consistent, dependable performance, maintaining the integrity of your vehicle’s factory-installed wiring.

Easy installation

Installing our module is incredibly straightforward

1. Disconnect the battery.
2. Unplug the connector on the car gateway (located in the footwell area under the dashboard).
   
3. Plug in the custom wiring harness with the module.
   
4. Reconnect the battery.

And that's pretty much it! You don't need any special tools. Check our detailed tutorial for more information.

Disclaimer: We recommend having it installed by a trained professional. While it’s easy to connect the included wiring harness into the car gateway, incorrect installation can cause major issues and could be a safety hazard. If you're not confident in your abilities, please use common sense and seek professional assistance.

Important Note: This device is for off-road use only. It is not road-legal and cannot be used on public roads.

Compatibility: Our module is compatible with all versions of Seat Leon and Cupra Leon built between 2020 and 2024 (before facelift) - both LHD and RHD versions. Even mild hybrid and CNG versions are supported. Plug-in hybrid is supported only partially (no start-stop memory). The plug-and-play wiring harness can only be installed in cars equipped with DSG transmissions. Installation in manual transmission cars is complicated by the presence of a clutch pedal. Currently, we are developing a wire harness specifically designed for manual transmission vehicles.
