Parts for your 2019 Audi Q5-Oil seals

2019 Audi Q5 Oil Seals — What They Do and When to Replace Them

Technical sources confirm the 2019 Audi Q5 absolutely uses oil seals throughout its powertrain. Audi’s erWin Workshop Manual for the FY-series Q5 (2018–2020) details radial shaft seals at the crankshaft (front and rear main), camshafts, transmission input/output shafts, and drive axles. The Audi ETKA parts catalogue likewise lists these seals under engine, gearbox, transfer case and final drive groups for the FY Q5 with 2.0 TFSI and S tronic drivetrains. These references make it clear: oil seals are integral to the Q5’s design.

For this model, oil seals keep engine oil, transmission fluid and final-drive oil where they should be, while keeping dust and moisture out. They also help maintain correct internal pressures. On the 2019 Q5, key seals include the front crank seal behind the pulley, the rear main seal between the engine and S tronic gearbox, camshaft seals at the timing end, axle flange seals at the transmission and rear final drive, and propshaft/output seals in the AWD hardware.

Oil seals aren’t a scheduled service item, they’re replaced when wear or age causes weeping or leaks. Modern VAG engines often use PTFE-style “dry” radial seals that require careful, clean installation with the correct installer sleeve and no grease on the sealing lip. Done right, they last years. If crankcase ventilation (PCV) is compromised or the sealing surface is scored, a new seal can still leak, so condition checks matter.

Things a workshop will watch for on a Q5:

• Fresh oil mist at the lower timing cover area (front crank), or oily residue at the bellhousing join (rear main).
• Dampness around axle flanges at the gearbox or rear diff, or drips onto the undertray.
• Burning-oil smell after a drive as oil hits the exhaust, or spots on the driveway.

Replacement advice for owners of a 2019 Q5: the rear main seal is a transmission-out job, budget time and labour. Axle and output seals are mid-level repairs, usually done with fluid changes and new flange bolts. Always use genuine-quality seals, follow Audi torque specs, and replace any worn wear-rings. Keeping engine oil changes timely and the PCV system healthy helps seal longevity. Ignoring leaks risks low oil levels, clutch contamination in the S tronic housing, or damaged bearings in the final drive—none of which are cheap to sort.

Popular questions about 2019 Audi Q5 oil seals

Does a 2019 Audi Q5 actually have oil seals?

Yes. Factory documentation (Audi erWin Workshop Manual, FY platform) and the ETKA parts catalogue list multiple radial shaft seals for the engine, S tronic transmission, transfer case/AWD hardware and final drive. They’re fundamental to keeping fluids in and contaminants out.

When should oil seals be replaced on a 2019 Q5?

There’s no set kilometre interval. They’re replaced when they leak or when related components are off for other work. Typical triggers are oil spots under the car, odours from oil hitting hot parts, or visible dampness at known seal locations. Good PCV operation and clean sealing surfaces extend service life.

What might it cost to fix a leaking rear main or axle seal in AU/NZ?

Ballpark figures vary with workshop rates and model variant. A rear main seal (gearbox out) often lands around AUD/NZD 1,500–3,000. An axle or output shaft seal is commonly AUD/NZD 350–900 per side, depending on fluid, hardware and labour. A proper inspection is the best way to firm up numbers.
