What does it mean when there are two rows of dots on the Lavida's glass date?
4 Answers
The meaning of two rows of dots appearing on the Lavida's glass date is: 1. The first row: numbers + small dots, where the numbers represent the year of glass production, and the small dots represent the months of that year. The minimum number of dots is 1, and the maximum is 12. 2. The second row: large dots + small dots, representing the days corresponding to the month; large dots represent 10 days, and small dots represent 1 day. More details about car glass dates are as follows: In addition to the above expression, there are two other ways to represent car glass dates: 1. Numbers + dots: The dots can be in front of or behind the numbers. The numbers represent the year, and the dots represent the months. If the dots are in front of the numbers, it indicates the first half of the year, and the month is calculated by subtracting the number of dots in front from 7. If the dots are behind the numbers, it indicates the second half of the year, and the month is calculated by subtracting the number of dots behind from 13. 2. Numbers + large and small dots: The numbers represent the year, small dots represent the quarter (there are 4 quarters in a year, with a maximum of 4 small dots), and large dots represent the months corresponding to the quarter (3 months per quarter, with a maximum of 3 large dots).
I recently researched the markings on car glass. The two rows of small dots in the corner of the Lavida's windshield are actually date codes used during production. Volkswagen vehicles commonly use this marking system: the numbers represent the year, and the dots represent the month. If the black dots are before the number, it indicates the second half of the year; if after, the first half. For example, if you see '..22.', it means February 2022 (dots on the right, 2 dots indicating 1+1=2 months); if it's '22..', it means August 2022 (dots on the left, 2 dots calculated as 13-2=11 months, but note the rule differences). Two rows of dots may appear on replaced windshields, indicating old and new production batch dates. Last month, while helping a neighbor inspect a car, I noticed two sets of markings on the passenger-side glass, mainly used to trace the source of parts. Remember to consider the position of the numbers for accuracy, as this is something many beginners often confuse.
Last time at the repair shop, the mechanic mentioned this detail. The dot matrix in the corner of the glass is actually the factory's production code. Volkswagen group prefers to use a combination of dots and numbers to mark the date. The numbers represent the last two digits of the year, while the dots serve as a month counter. The key is the position of the dots relative to the numbers: when the dots are before the numbers (e.g., · · 23), subtract the number of dots from 7 to get the month; when the dots are after the numbers (e.g., 23 · ·), simply add 1 to the number of dots. Two rows of dots indicate that the glass may have undergone secondary processing or recorded different production stages on the assembly line. Once, I noticed two sets of marks on my friend's car glass: ··20 and ·21, indicating the glass substrate was produced in 2020, while the coating process was completed in 2021. This is common in older Lavidas that have had their glass replaced, which doesn't affect usage but reveals the history of the parts.
The tiny dots on car windows hide production secrets. In Volkswagen's glass markings, those dots serve as month calculators. The numbers represent the year; for example, the number 23 stands for 2023. Key identification technique: Determine whether the dots are on the left or right side of the number. When dots are on the right (like this 23···), count the dots directly—4 dots mean May (number of dots +1). When dots are on the left (···23), subtract the number of dots from 13—3 dots indicate October. Two rows of dots are likely date records from different production stages. When I helped my dad inspect his decade-old Lavida, the driver's side window had two rows of numbered dots. The auto repair shop explained it retained dual markings: the original production date and the replacement date when the glass was changed.
