HELP!!! I had my car inspected last week and to my unpleasant surprise, Hong Kong's MOT informed me the vehicle's tailgate glass is too dark and thus failed to meet local regulations - the car had just recently arrived from the UK. As the car seems stock to me, I was wondering if anyone can inform me if indeed Audi offered a tint option. My car is equipped with the open sky sunroof so does that have a bearing on the colour of the rear windows and tailgate? I've spoken to a local Audi parts distributor but they weren't sure. Any assistance would be greatly appreciated. I have a sinking feeling that I will need to order an entirely new glass panel...totally gutted...would be even worse if I ordered the wrong part!
