Valve operation with the ECE-approved version
During driving, you can choose between Comfort and Sport modes. If the vehicle has drive profile selection, the system can be controlled through this function. On vehicles without drive profile selection, the valve can be controlled using the supplied switch. The switch’s LED indicates the valve status: the light is off when the valve is open and on when it is closed.
- Sport (Dynamic, Race): the valve remains open within the permitted ECE operating range and is always closed when stationary.
- Comfort: the valve remains closed, opening during driving within the permitted ECE operating range once the throttle is at least 75% open.
Operation without ECE approval
With versions using switch-operated, remote-operated or Bull-X Tronic “Race” Can-Bus valve control, the valve can be controlled through the drive profile selection or the supplied switch if the vehicle does not have this function. Versions without ECE approval are intended exclusively for track use.
Suitable for: Audi S3 II (8P).
