🔩 Torque settings

Values can differ between engine variants — check the code stamped on your block.

ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.

📋 Procedure

1. From menu (1), select function "„Measured values“" and advance by pressing → button.
2. Using keypad (1) press button 4 for "„Display group 004“" and confirm entry by pressing Q button.
3. Read off ATF temperature in display zone (1). [Note: The ATF level is checked at the ATF inspection hole.The ATF level is correct if a small amount of fluid comes out at the ATF inspection hole when ATF temperature is between 30°C and 45°C, or 50°C in hot climates (the fluid level rises due to expansion as it warms up).]
4. ⚠ The ATF filling unit must be clean and the ATF must not be mixed with other types of ATF! — Fill the ATF filling unitV.A.G 1924 with the ATF for the automatic gearbox 01L.
5. Secure reservoir for ATF filling unit V.A.G 1924 as high as possible on vehicle.

6. Place used oil collection and extraction unitV.A.G 1782 below gearbox.
7. ⚠ Wear safety goggles. — When ATF reaches temperature of 35 °C, unscrew plug (2) for ATF inspection hole.
8. Cut open seal (arrow) for plug and renew. [Note: When the plug is opened, a small amount of ATF will always run out initially (arrow).] [Note: The ATF inspection plug must be screwed in again at the latest when the ATF reaches a temperature of 45 °C (countries with hot climates: 50 °C).If ATF temperature exceeds 45 °C too much fluid will escape as it expands when heated. In this case the quantity of fluid in the gearbox is NOT sufficient!]
9. Fit new seal on plug for ATF inspection hole and tighten.
10. Exit from function "„Measured values“" by pressing ← button.
11. Press "„End output“".
12. Switch off ignition and unplug diagnostic connector.
13. Guide filler nozzle (arrow) of ATF filling unit V.A.G 1924 through ATF inspection hole into an opening in the deflector cap, taking care not to push the deflector cap upwards out of position.
14. Fill with ATF using ATF filling unit until ATF comes out of inspection hole. [Note: The ATF inspection plug must be screwed in again at the latest when the ATF reaches a temperature of 45 °C (countries with hot climates: 50 °C).If ATF temperature exceeds 45 °C too much fluid will escape as it expands when heated. In this case the quantity of fluid in the gearbox is NOT sufficient!If necessary, switch off engine and allow gearbox to cool down.]
15. Fit new seal on plug for ATF inspection hole and tighten.
16. Exit from function "„Measured values“" by pressing ← button.
17. Press "„End output“".
18. Switch off ignition and unplug diagnostic connector.
