Parts for your 2019 Audi Q5-Drive belt pulley

2019 Audi Q5 drive-belt pulleys: what they do and when to service them

Yes, a drive-belt pulley system is fitted and absolutely relevant on the 2019 Audi Q5 (FY). Audi’s factory repair information for the FY-platform Q5 (erWin/ELSA Repair Manual, “Poly V-belt – layout/renewing,” 2.0 TFSI EA888 Gen.3B and 3.0 TFSI EA839) details a serpentine belt driving key auxiliaries via multiple pulleys. Audi Self‑Study material for the EA888 Gen.3B and EA839 also shows the accessory drive with a torsional vibration damper (crank pulley), automatic tensioner and idlers, while supplier technical notes from Schaeffler INA cover the overrunning alternator pulley used on these engines.

On this Q5, the poly‑V belt and its pulleys transfer crankshaft rotation to essential accessories, keeping charging, cooling and cabin comfort on song. The pulley set typically includes:

• Crankshaft vibration damper (main drive pulley)
• Automatic tensioner and one or more idler pulleys
• Overrunning alternator pulley (OAP/OAD)
• Air‑conditioning compressor pulley

Unlike older hydraulic systems, the 2019 Q5 uses electric power steering, so there’s no belt‑driven power steering pump pulley to worry about.

Typical wear signs owners or techs might notice include belt chirps on cold starts, a fluttering belt, charging fluctuations, A/C performance dropping at idle, or a rough wobble at the crank damper. A failing overrunning alternator pulley can cause a brief rattle on shutdown or a belt “snatch” as revs fall. Left too long, a seized pulley or weak tensioner can shred the belt and strand the vehicle.

Service-wise, Audi doesn’t prescribe a hard‑and‑fast interval for the poly‑V belt on these engines, but workshop best practice in Australia and New Zealand is to inspect at every service and plan renewal around 100,000–150,000 kilometres, or earlier if there’s any cracking, glazing, edge fray, noise or dusting. When the belt is replaced, it’s smart to assess the whole system:

• Spin and check the alternator OAP/OAD for smooth one‑way operation
• Replace the automatic tensioner and any noisy idlers together with the belt
• Inspect the crankshaft damper for rubber delamination or wobble
• Confirm correct belt routing and tensioner preload after fitting

Using OE‑equivalent components and following the Audi Q5 (FY) Repair Manual procedures helps avoid comebacks. These recommendations are based on: Audi erWin/ELSA Repair Manuals for Q5 (FY) 2.0 TFSI EA888 Gen.3B and 3.0 TFSI EA839, “Poly V‑belt” sections, Audi Self‑Study Programmes covering EA888 Gen.3B and EA839 accessory drives, and Schaeffler INA technical literature on Overrunning Alternator Pulleys (OAP/OAD).

Popular questions about 2019 Audi Q5 drive-belt pulleys

Does the 2019 Audi Q5 have an overrunning alternator pulley?
Yes. The FY‑platform Q5 uses an overrunning alternator pulley (OAP/OAD) to decouple alternator inertia during rapid RPM changes. This smooths belt motion, reduces noise and protects the tensioner. If it rattles at idle or on shutdown, or the belt flutters, the OAP/OAD should be tested and replaced if rough or seized.

When should the drive belt and pulleys be replaced?
There’s no fixed kilometre interval in the factory schedule, they’re inspected during routine servicing. Many workshops in AU/NZ renew the belt around 100,000–150,000 km as preventative maintenance, replacing the tensioner and any noisy idlers at the same time. Replace sooner if there’s cracking, glazing, squeal, or if the alternator pulley fails functional checks.

Is there a power steering pump pulley on this model?
No. The 2019 Q5 uses electric power steering, so there’s no belt‑driven power steering pump. The belt drives the alternator, A/C compressor and runs over the damper, tensioner and idlers only.
