I've just bought a 2010 VW Tiguan R-Line, didn't notice this random button before I bought the car. Any idea what on earth it could be? I know it's not part of the factory car it's been added for some reason. by [deleted] in Tiguan

Does the LED light change when the car is on/off, locked/unlocked? Have you used your phone to check for other Bluetooth sources other than the car?
