Windscreen Stress Crack
After a few weeks, I went out to my car and found a stress crack on the screen.
Aston Green Slough acknowledged it as a fault and it was replaced under warranty.
This is a common fault specially for bonded windscreens, if a car is driven shortly after a new screen is fitted there is a better chance of it flexing and settling into a good seat.
New Audis are left to stand before being delivered which means the glass bond could dry under stress which it exerts on the screen hence the stress crack.
If you get one, either take photos or put tape on it until its shown to a dealer.
