Audi A4 Allroad, 8KH (EU)

Additional Notes

• The S tronic dual-clutch transmission used across the Audi A4 Allroad 8KH is specified in two separate fluid compartments: a clutch part and a transmission part. Each compartment carries its own distinct fluid capacity, and the two figures are not interchangeable or additive in a single-fill context.
• The clutch part of the S tronic unit carries a service fill capacity of 6.7 liters across all engine variants in the lineup. A service fill represents the quantity needed when fluid is changed with the transmission remaining in the vehicle and some residual fluid is retained, rather than a fully drained state.
• When the S tronic clutch part is filled from a completely dry state, capacity rises to either 7.5 liters with an oil cooler fitted or 7.0 liters without one. The 0.5-liter difference reflects the additional fluid volume held within the oil cooler circuit itself.
• The S tronic transmission part carries a dry fill capacity of 4.35 liters across all engine variants listed, from the 2.0 TDI 120 kW through to the 3.0 TDI 180 kW. No service fill figure is listed for the transmission part, only the dry fill value.
• The conventional automatic transmission fitted to the 2.0 TFSI 155 kW (2010-2013) and 2.0 TFSI 162 kW (2013-2016) variants uses a notably different capacity structure. Dry fill ranges from 8.6 to 9.0 liters, while service fill ranges from 3.6 to 4.0 liters, reflecting a much larger residual volume retained during a standard fluid change compared to the S tronic clutch part.
• The service fill capacity of the conventional automatic transmission, at 3.6-4.0 liters, represents less than half of the dry fill volume of 8.6-9.0 liters. This wide gap is typical of torque converter automatics, where a significant portion of fluid remains in the torque converter and hydraulic circuits even after a drain.
• The 2.0 TFSI 155 kW variant covers two distinct production periods in the specifications: 2009-2010 with only the S tronic listed, and 2010-2013 where both the conventional automatic and the S tronic are listed. This indicates two different transmission options were available for the same engine output during the 2010-2013 period.
• A fluid check interval of every 24 months or 30,000 km under normal use conditions is specified for both the clutch part and the transmission part of the S tronic on all 3.0 TDI variants, covering the 176 kW (2009-2012) and 180 kW (2012-2016) engines. No equivalent check interval appears in the specifications for the 2.0-liter engine variants.
• The 3.0 TDI 176 kW engine spans two consecutive model year ranges in the specifications: 2009-2010 and 2010-2012. Both ranges carry identical S tronic capacities and the same 24-month/30,000 km check interval, with 2010 appearing as a shared boundary year between the two entries.
• All specifications across every engine variant and model year in the lineup are designated for normal use conditions. No severe-use or alternative-condition intervals are listed for any entry.
