Solution

1. Preparation

Gather necessary tools: a clean lint-free cloth and a funnel.
Ensure the vehicle is on a level surface and the engine is warm.
Wear safety gloves to protect your hands.

2. Access the Transmission Dipstick

Open the hood and locate the transmission dipstick (if equipped) or fill plug.
If necessary, remove any engine covers that obstruct access to the dipstick.

3. Check Fluid Level

Remove the dipstick or fill plug carefully.
Wipe the dipstick clean with a lint-free cloth.
Reinsert the dipstick fully, then remove it again to check the fluid level.
The fluid level should be within the marked range (typically between the "MIN" and "MAX" lines).

4. Add Fluid if Necessary

If the fluid level is below the "MIN" mark, use a funnel to add the appropriate transmission fluid.
Add fluid slowly, checking the level frequently to avoid overfilling.
Confirm the fluid is the recommended type for your Volkswagen Passat B8 (often VW G 052 162 A2 or equivalent).

5. Replace Dipstick or Fill Plug

Once the correct fluid level is achieved, securely replace the dipstick or fill plug.
If any engine covers were removed, reinstall them as necessary.
