Our FAQ’s ?🙋‍♂️🙋‍♀️?

"Can the exhaust valves stay closed during cold start?"

“Due to the nature of the stock vacuum system on the “Audi vacuum solenoids) they operate under vacuum pressure so if the car still has pressure in the system, you will be able to switch the flap on/off just having the ignition switched on.
If the car has been stood for some time, the vacuum will not be pressurised until you start up again.
We can promise when you start up, this remote will switch the flaps instantly. So once you press start on your car, press the closed flap “ON” button to make it quiet instantly.”

Is the “Chapatronics” controller device box safe from grime and water?

“Yes! the Chapatronics controller box with the OEM wiring harness, is fully waterproof therefore no grime or oils can get in. (We also recommend you zip tie your controller box out the way of sharp objects or hot areas, such as exhaust pipes)”
