It's about -3C now (23F) and the windshield is making creaking noises
for quite a while after I start driving the car in the morning (snow's
falling)

I had the windshield replaced this august with the very same (french)
glass
which I think is the same that is used by ingolstadt on the new audis

the car was sitting idle for the 24 hours after the new windshield was
installed
for the glue to cure properly. plus 25-30C heat back then should have
helped
the curing

not sure if my a4 was drying in the hangar bay of the glass shop or
outside in direct sunlight

thoughts on this and the best time of year to do the inexpedient
windshield replacement?
