What does it mean when there are two rows of dots on the Lavida's glass date?

The meaning of two rows of dots on the Lavida's glass date: First row: Number + small dots, the number represents the year of glass production, and the small dots represent the month of that year. The month can have a minimum of 1 dot and a maximum of 12 dots. Second row: Large dots + small dots, representing the days corresponding to the month; large dots represent 10 days, and small dots represent 1 day. Meaning of number + dots: The dots can be in front of or behind the number. The number is the year, and the dots represent the month. If the dots are in front of the number, it represents the first half of the year. Subtract the number of dots in front from 7 to get the month in the first half of the year. If the dots are behind the number, it represents the second half of the year. Subtract the number of dots behind from 13 to get the month in the second half of the year. Meaning of number + large and small dots: The number represents the year, the small dots represent the quarter. There are 4 quarters in a year, with a maximum of 4 small dots. The large dots represent the months corresponding to the quarter, with a maximum of 3 large dots since a quarter has 3 months.
I have some knowledge about automotive glass, and those small dots are actually production date codes. For the Lavida, the date markings on the windshield typically appear as two rows of dots—the left row usually indicates the production year, while the right row represents the month. The number of dots corresponds to specific digits: for example, the month section may have 1 to 12 dots, representing January to December, while the year section might use dots to denote the last two digits of the year or a specific code. This is a common practice in safety glass standards, designed to help owners or technicians identify the production time of the glass, ensuring replacements match the original factory specifications. I've found this not only helps determine if the glass was replaced after an accident but also verifies the vehicle's history during used car transactions—if the glass date predates the car's production date, it might be a refurbished part. As a mainstream Volkswagen model, many Lavida owners are curious about this. I suggest using a bright light to carefully count the dots and match them with the car's age. If the dots are too faint to read, don't overthink it—just visit a professional shop for inspection. Remember, never overlook the glass date—safety comes first!
