Audi A1, S1, 8X (EU)

Transfer case fluid capacity & service interval

Audi A1, S1, 8X (EU) models use transfer case fluid with a capacity of 0.9 liter. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
  • S1 2.0 TFSI quattro (170 kW) (2014-2018)
  • Angle gearbox
  • Use: Normal
  • Capacity 0,9 liter
  • A1 2.0 TFSI quattro (188 kW) (2012-2013)
  • Angle gearbox
  • Use: Normal
  • Capacity 0,9 liter

Additional Notes

  • Both quattro configurations listed across the 2012-2018 period share an identical transfer case fluid capacity of 0.9 liter, which is a relatively small volume consistent with a compact angle gearbox or transferbox unit rather than a larger standalone transfer case assembly.
  • The Audi A1 2.0 TFSI quattro (188 kW), covering 2012-2013, carries a 0.9 liter capacity figure designated for normal use conditions, meaning the interval and fill quantity apply to standard operating environments rather than elevated stress or temperature cycles.
  • The S1 2.0 TFSI quattro (170 kW), spanning 2014-2018, shares the same 0.9 liter normal-use capacity despite representing a higher-trim, performance-oriented variant with a different power output rating than the earlier A1 configuration.
  • The power output difference between the two variants is notable in context: the A1 2.0 TFSI quattro is rated at 188 kW while the S1 2.0 TFSI quattro is rated at 170 kW, yet the transfer case fluid capacity remains unchanged at 0.9 liter across both.
  • A capacity of 0.9 liter in a transfer case context typically reflects a service fill specification, representing the amount of fluid used during a routine drain-and-refill procedure rather than a full overhaul or dry-fill quantity.
