BMW 840i (G14 G15 G16) RX1 (BE1) ASR exhaust flap control

ASR Flap Control RX1 – For BMW 840i (G14/G15/G16)
More control, more sound, more driving pleasure: The ASR RX1 exhaust valve control allows you to manually control the electric exhaust valve of your BMW 840i – simply via a high-quality remote control. This way, you always have complete control over the sound of your vehicle.

Full control over the sound

With the RX1 control, you can switch between the available exhaust flap modes independently of the Drive Select function. The driving profile no longer determines the sound – you are completely in control.

Advantages of the ASR RX1 at a glance

• Regardless of Drive Select – Sound control can be manually adjusted at any time

• True series mode Even after the vehicle has started – ideal for workshops, service or vehicle inspections

• Freely programmable start mode – last state or desired mode at startup

• No interference with the CAN bus – no risks to other control units, no impact from software updates

• Plug-and-play assembly – vehicle-specific original connectors, reversible without leaving any traces

• No error messages in storage

• High-quality remote control – brushed stainless steel front, long range

Start mode – individually adjustable

You determine which mode your vehicle should start in after switching on the ignition. Whether the last state or a defined mode – the RX1 can be flexibly programmed and confirms successful settings via the movement of the exhaust flaps.

Simple plug-and-play installation

Installation is done directly at the exhaust flaps using the original connectors. We recommend mounting it in the trunk for optimal reception and protection from the elements. The cable lengths are already appropriately designed for this purpose.

Quality Made in Germany

The RX1 was specifically developed for electric flap systems and offers reliable, long-lasting operation – without any modifications to the vehicle software.
