The passenger door needs shutting quite hard otherwise it doesn't shut all the way
The other, which I only noticed the other day is the fan vent on the drivers side, I had the C/C on fully blowing through the vents instead of on the screen, I then shut the passenger one, the two in the middle and the drivers one and noticed that the drivers one was still letting air out.
Strange I thought, turns out that the vent doesn't shut whether you turn the slider or not.
I bet there's no chance of VW doing this for Free is there (it is under warranty) I've had the car for roughly 5 or 6 months.
