How to Check the Year of BMW 5 Series Windows?

[DelLyla]

Method for checking the year of BMW 5 Series windows: There is a code in the lower left corner of the window. In addition to identifying the manufacturer, window brand, and national certification code, the production date is also included. The year is represented by a digit, which is the last digit of the year. There will be a series of small black dots either before or after the digit. If the black dots are before the digit, subtract the number of dots from 7. If the black dots are after the digit, subtract the number of dots from 13. The result is the production month of the window. Taking the BMW 5 Series 2021 525Li Luxury Package as an example: It is a mid-to-large-sized car launched by BMW Brilliance, with a length, width, and height of 5106mm, 1868mm, and 1500mm respectively, and a wheelbase of 3105mm. It is equipped with a 2.0T turbocharged engine, with a maximum power of 135kw, and matched with an 8-speed automatic transmission.
