How to Check the Production Date of Volkswagen Car Glass?
3 Answers
The method to check the production date of Volkswagen car glass is: 1. Locate the numbers and black dots on the glass. The specific numbers and the count of black dots indicate the year and the production period. The number represents the year, dots before the number indicate the first half of the year, while dots after the number indicate the second half of the year. The number of dots represents the number of months before or after the midpoint of the year. 2. If the dots are before the number, subtract the number of dots from 7; if the dots are after the number, subtract the number of dots from 13. This will give you the correct production date based on the number and the count of black dots. Taking the 2021 Volkswagen T-Roc as an example, it is a compact SUV with the following dimensions: length 4318mm, width 1819mm, height 1582mm, wheelbase 2680mm, fuel tank capacity 51 liters, and curb weight 1385kg.
As a Volkswagen owner, I was also curious at first about how to find the glass production date. Usually, it's located in the lower left or right corner of the window, with a small imprint like an engraved square or circle. You need to look carefully—sometimes dirt on the glass can obscure it, so clean it first. There's a number and a few dots inside, such as the number 6 with three or four dots next to it. The number represents the last digit of the year, like 6 for 2016 or 2026, and the dots represent the week number—one dot for one week, five dots for the fifth week. When I first checked, I thought it was maintenance records, but later I learned its importance—for example, glass aging can affect safety. But remember, this is just a production date mark and doesn’t affect usage. Volkswagen cars are mostly the same; after finding it, you can cross-check with online charts. In practice, opening the hood or crouching down for a better angle makes it easier to spot.
I've been driving for decades, often behind the wheel of Volkswagen models, and I have experience checking glass dates. Usually, you'll find a small mark in the corner of the window—it's a combination: digits before or after dots indicating the week number. If the number is 4, it might mean 2014, and the number of dots, say 7, represents the 7th week. When I was younger, I didn't understand this. After buying a used car, I checked the glass dates and found different dates on different windows, which is normal due to varying production batches. I remind myself to use good lighting—shine a flashlight at night for clarity or check in the early morning when there's less condensation on the glass. Knowing the date helps estimate the glass's lifespan; Volkswagen glass may develop cracks after about ten years and needs inspection. Beginners, don't rush—practice makes perfect. This is one of the basic car maintenance skills.
