Does anyone have a clue why my S3 windscreen should suddenly and inexplicably crack on the drivers side in front of the steering wheel and heading up to half way up the RHS pillar? The car has been tucked up since October with the trickle charger on. Went to the man cave last night (as I do nearly every day) and there it was. The car is 18 months old and was not hit by anything last time out at the end of September. The garage is a pretty constant temperature.

Is this area highly stressed ? Do not understand why it's suddenly gone.
