Volkswagen Polo with an automatic transmission does not have a traditional dipstick for checking the fluid level in the automatic transmission.
Instead, the level and condition of the automatic transmission fluid is checked through a special diagnostic hole using special equipment such as a scanner or a dealer diagnostic tool.
Some Volkswagen Polo models with an automatic transmission may have an inspection window on the automatic transmission housing, through which you can visually assess the color and transparency of the fluid, but it does not allow you to accurately check the level.
It is recommended that you have your automatic transmission fluid level checked and other automatic transmission related service performed by a certified mechanic or Volkswagen dealership.
