Additional Notes

  • The Volkswagen Passat A34 2.0 TFSI automatic transaxle carries an initial fill capacity of 7 liters, a figure associated with a full overhaul or dry fill where the entire fluid circuit, including the torque converter, is replenished from empty.
  • The refill capacity of 3 liters applies to a partial drain-and-fill service, where residual fluid remains in the torque converter and valve body, reducing the total volume needed to restore the system to the correct level.
  • The gap between the 7-liter initial fill and the 3-liter refill reflects that roughly 4 liters of fluid is retained in the transmission assembly during a standard service drain, which is a common characteristic of automatic transaxle designs.
  • Under normal use conditions, the automatic transaxle fluid on the 2.0 TFSI is subject to a check interval of every 20,000 miles or 24 months, whichever comes first, rather than a change at that point.
  • The fluid change interval under normal use is set at 80,000 miles, placing the first drain-and-fill service well beyond the initial check intervals that precede it.
  • The 2019-2020 and 2020-2022 Passat 2.0 TFSI configurations share identical capacity and interval specifications, with the 2020 model year appearing in both ranges as an overlap point between the two listed configurations.
