True series mode – even after restarting
Ideal for workshop appointments, service or MOT: With the module deactivated, everything remains close to the original factory settings.

Freely programmable start mode
Customize the sound directly when starting the engine. Whether it's the last setting or a fixed mode – the setting can be easily learned.

No interference with the CAN bus
No risks to other control units and no impact from software updates.

Plug-and-play installation
Original connectors, no cable damage, no soldering. Installation is simple and reversible without leaving any residue.

Start mode – individually adjustable

The start mode determines the flap status in which the vehicle starts after the ignition is switched on.

• Last state: Press the Sport button five times within 5 seconds.
