How does it work?

With the dAHLer Valve Controller installed you can manually open and close the standard built-in exhaust valve of your BMW at any time. It operates at the push of a button on the in delivery included remote control or can be programmed to your mirror buttons, so the system will be very well integrated.

Installation of the dAHLer Valve Controller in your BMW is easy and can be carried out by anyone with a little manual skill. The device is a direct plug in to the existing (OEM) harness. You pull out the original plug and connect it to the socket. The other plug is then connected to the socket on the exhaust flap and the connection is done.

The complete installation takes place in the trunk and under-body. You look for a cable duct or unused sealing plug that leads from the inside to the outside. Power supply comes directly from the original plugs and there is no need to lay cables through the interior of the vehicle.

With our smart Valve Controller Module, one cannot close the exhaust flap permanently. This is for safety reasons as when driving at full throttle with the exhaust valve closed it could damage the engine in a long term.

Memory and Start Mode
