Additional Notes

  • The Audi A6 1.8 TFSI (140 kW), covering 2014-2018, carries a notably lower manual transaxle fluid capacity of 1.8 liters compared to all other listed configurations, which hold 4 liters. A capacity this small relative to other units in the same model family typically reflects a physically smaller gearbox housing designed around a lower-torque application.
  • The 4-liter transaxle capacity appears across six configurations spanning the 2010-2014 period, including both diesel and petrol variants: the 2.0 TDI (100 kW, 120 kW, and 130 kW), the 2.0 TFSI (132 kW), the 2.8 FSI, and the 3.0 TDI (150 kW). A uniform fill volume across engines of differing displacement and fuel type indicates a shared or dimensionally equivalent gearbox unit across those variants.
  • All seven configurations share an identical service interval of 24 months or 30,000 km under normal use conditions. The dual-trigger format, where whichever limit is reached first applies, accounts for vehicles that accumulate low annual mileage, ensuring time-based fluid degradation is also addressed.
  • The interval specifications are designated for normal use conditions across all listed rows. No severe-use interval is listed for any of the manual transaxle configurations in the Audi A6 4G (EU) range covered here.
  • The three 2.0 TDI variants, rated at 100 kW, 120 kW, and 130 kW respectively, all share the same 4-liter capacity and 24-month/30,000 km interval despite differing power outputs. Power output variation within a diesel engine family is often achieved through software calibration or turbocharger tuning rather than changes to the transmission unit itself, which aligns with the identical fluid specifications seen here.
  • The 2.0 TDI (100 kW) covers model years 2012-2014, while the 2.0 TDI variants at 120 kW and 130 kW both span 2011-2014. All three share the same transaxle fluid capacity and service interval, though the 100 kW variant entered the specification range one year later than the other two diesel four-cylinder configurations.
  • The A6 2.8 FSI and A6 3.0 TDI (150 kW) both begin their listed year range in 2010, making them the earliest configurations in the dataset. Both carry the 4-liter transaxle capacity and the standard 24-month/30,000 km check interval under normal use.
