Audi Q5, SQ5, 8R (USA)

Additional Notes

• The Audi Q5 2.0 TFSI Hybrid quattro (8R, 8RB) carries a distinct initial fill capacity of 1 liter for the front differential sourced from the automatic transmission, while the refill capacity drops to 0.9 liter. This difference between initial fill and refill values reflects the volume lost during a fluid drain, where a small amount remains in passages and cavities that a full overhaul fill would otherwise account for.
• The rear differential on the Q5 2.0 TFSI Hybrid quattro (8R, 8RB) for 2012-2017 holds 0.9 liter with no separate initial fill and refill distinction, meaning a single capacity figure applies regardless of whether the unit is being filled from dry or serviced in place.
• On the Q5 2.0 TFSI quattro at 155 kW (2010-2013), the rear differential capacity is specified at 1.1 liters, which is slightly higher than the 1.0 liter front differential figure for the same configuration. This small difference indicates a marginally larger fluid sump in the rear unit for that engine variant.
• The Q5 2.0 TFSI quattro at 162 kW (8R, 8RB, 2013-2017) lists both the front differential from automatic and the rear differential at 1.0 liter each, with no distinction between initial fill and refill. The rear differential capacity on the 162 kW variant is therefore 0.1 liter less than on the earlier 155 kW version.
• Across the Q5 3.0 TDI quattro (176 kW), Q5 3.0 TFSI quattro (200 kW), and SQ5 3.0 TFSI quattro (260 kW) for 2013-2017, all front and rear differential capacities are uniformly specified at 1.0 liter, with no variation between the diesel and petrol variants at those outputs.
• The Q5 3.2 FSI quattro (199 kW) covering 2008-2012 also carries a uniform 1.0 liter capacity for both the front differential from automatic and the rear differential, consistent with the later 3.0-liter configurations despite the different engine architecture.
• A first check only interval of 15,000 miles applies across all listed configurations as an earlier inspection point compared to the standard normal use interval of 20,000 miles. The first check only designation means the shortened interval applies solely to the initial service after the vehicle enters use, after which the standard 20,000-mile cadence takes over.
• The time-based component of the service interval differs between earlier and later configurations. The Q5 3.2 FSI quattro (199 kW) and Q5 2.0 TFSI quattro at 155 kW specify a 12-month time limit alongside the mileage interval, while the Hybrid quattro variants and the 162 kW, 176 kW, 200 kW, and 260 kW configurations all carry a 24-month time limit. Whichever threshold is reached first, mileage or time, would trigger the service.
