Screen seems original as it's still got alfa sticker warning U to put oil in the engine!
If it's like the examples on the cars I've driven today ('52' and '05' Registrations) Pilkington glass has a manufacturer's date code below the Alfa and Pilkington trade-marks.
My late 2001 - '52' 147 has date codes Feb - April 01.
Dots for months and a central number for the year 0 to 9.
. . 4 is Feb 2004,
. . . . . . 4 is Jun 2004
I believe for the the Jul to Dec months, 1 to 6 dots to the right of the year number are shown.
2 . is Jul 02 and
2 . . . . . . is Dec 02
So if the screen has a date code later than the date of manufacture or registration of the vehicle you know its been replaced. (It could still have been replaced of course if the date codes are similar depending when it was done or when the replacement screen manufactured.)
For this to be a common fault with the 156 it would appear to be a manufacturing / assembly process fault on the assembly line. But getting Alfa to admit that......
If there are bubbles due to corrosion under the undamaged paint it looks as though it's not due to external damage (stone chips). Whether this constitutes "perforation" and is covered by the 5 year(?) warranty I guess is down to the dealer unless a body-shop or AA/RAC can help with any definitive report?
