Additional Notes

  • The transfer case fluid capacity for the Audi A5 Cabriolet 2.0 TFSI quattro (155 kW) covering 2009-2013 and the 162 kW variant covering 2013-2015 is a uniform 1 liter, with no distinction made between initial fill and refill volumes.
  • Starting with the 8F7 body designation for the 162 kW variant from 2015-2017, the transfer case specifications split capacity into two distinct values: 1.1 liters for initial fill and 0.8 liters for refill. The difference between these two figures reflects the volume of fluid that remains in the unit after a drain, meaning a full refill does not require the same quantity as a first-time fill from empty.
  • Across all six configurations, the normal-use service interval for the transfer case is a fluid check at 20,000 miles or 24 months, whichever comes first.
  • A separate first-check-only interval of 15,000 miles or 24 months applies to every configuration listed. Under a first-check-only condition, the earlier mileage threshold applies solely to the initial inspection, after which subsequent checks revert to the standard 20,000-mile or 24-month cycle.
  • The 5,000-mile difference between the first-check-only interval and the normal interval is consistent across all three generational variants, spanning the full 2009-2017 range covered in the specifications.
  • The 24-month time limit is identical for both the normal and first-check-only intervals in every configuration, meaning the time-based threshold does not change between the two use conditions, only the mileage threshold does.
  • The capacity increase from 1.0 liter to 1.1 liters for initial fill in the 2015-2017 8F7 variant indicates a slightly larger transfer case unit compared to the earlier 155 kW and 162 kW configurations, even though the engine output rating of 162 kW is shared with the preceding 2013-2015 variant.
