I have for sale an exhaust valve controller I have now removed from my 2014 RSQ3. Only around 8 months old and in perfect working order. This allows you to have the flaps fully open without having to run the car in sport mode constantly. You can also run the flaps in sequence as they normally do if you like via 2 options on the controller.
This is a really easy item to install, plugging straight into the exhaust valve and sounds great. The only reason I have taken it off is because I now have my exhaust mapped open all the time and no longer require it.
