Does anyone know what the Sungate PPG numbers mean on MB vehicle glazing (example shown above) - specifically if the four numbers directly beneath the MB logo and "Sungate EA" on W221 S Class front side windows?

All the numbers on my broken glass (from top to bottom) are:

"MB Star logo"
Sungate EA
27 1 4 8
DOT 18PPG AS2 M700
E11 (in a circle)
43R-00257
E000249
"CCC" (in circle)
E 000249
E11

I've found several candidate pieces of glass and all the numbers match except the four numbers beneath the Sungate EA: 27 1 4 8

I've found several variations of these four numbers but only one exact match (which I promptly bought but it came poorly packaged and had broken en-route) and i'm wondering if anyone knows what they represent (year of production, tint level, production plant ID, glass thickness, climatic region of initial delivery destination, etc.....) and if they even matter - or whether any piece that fits the W221 will work. My fear is that a piece with a different number sequence will physically fit but will have a different and noticeable tint level and compromise the aesthetic of the vehicle.

If there are any other 2009 W221 S63 owners out there willing to share what numbers are found on their cars it would be MUCH appreciates as no one seems to offer refunds on auto glazing via ebay.

Cheers,

Thanks, PM.

I really appreciate you taking the time and trouble to send the WIS glazing details. Unfortunately, the A- part number isn't what i'm looking for. It seems that most all W221 S-Class models have the exact same MB part number, but the actual numbers etched on the glass (presumably by the glass manufacturer) differ - from model to model, year to year, car to car??? I am trying to figure out if the different numbers etched/printed onto the glass have any substantive value (indicative of a different tint color/level perhaps?) or whether they're just year to year or factory to factory changes but the physical window specs are essentially meaningless and any replacement MB glass with the same A- part number will do.

Any further guidance, from any forum member, would be much appreciated.
