How to Identify the Production Date of BMW Glass?
2 Answers
The small black dots indicate the production month of the glass. If the black dots are in front of the number, subtract the number of dots from 7. If the black dots are behind the number, subtract the number of dots from 13. The number following the black dots represents the production year of the glass.
Finding the production date of BMW glass is actually quite easy, and I often help friends check this. You mainly need to look at a small corner of the car window or windshield, where there’s usually a string of imprints with numbers and small dots. The numbers typically represent the last two digits of the year—for example, '22' means 2022. The dots indicate the month, with more dots meaning a later month. Sometimes, the exact position of the dots also determines whether they represent the month or day. For instance, three dots might indicate March. From my experience, comparing the glass date with the vehicle's manufacturing year can reveal whether the glass has been replaced. If there’s a significant discrepancy, it might suggest the car was involved in an accident or underwent repairs. Next time you wash your car, take a quick glance—using your phone’s flashlight can help, especially when glare makes it hard to see. Developing this habit can help you spot issues early and save you from hefty repair costs later on.
