Differential fluid capacity & service interval

Volkswagen Atlas, CA1, CA2, CA3 (USA / CAN) differential fluid capacity is 0,95 liter. Service intervals consist of a check every 20000 miles or 24 months. The data covers 3 configurations.

Additional Notes

  • The Volkswagen (VW) Atlas rear differential holds 0.95 liter across all 4Motion configurations covered in the specifications.
  • A capacity of 0.95 liter is a relatively modest fill volume, consistent with a compact rear differential unit rather than a larger axle assembly requiring a full overhaul quantity.
  • The 2.0 TFSI 4Motion covering model years 2017-2018 and the 3.6 V6 FSI 4Motion covering the same years share an identical rear differential capacity of 0.95 liter, indicating no variation between the four-cylinder and six-cylinder drivetrains in that regard.
  • The 2.0 TFSI 4Motion with a starting year of 2023 carries the same 0.95 liter rear differential capacity as the earlier 2017-2018 variant of the same engine configuration.
  • All rear differential entries in the specifications are assigned a normal use condition, with a check interval of 20,000 miles or 24 months, whichever comes first.
  • A check interval rather than a drain-and-fill interval means the service action at 20,000 miles or 24 months is a fluid level inspection, not a scheduled fluid replacement.
  • The 24-month time component of the check interval functions as a parallel trigger to the mileage threshold, so lower-mileage vehicles still reach a service point on a calendar basis.
