Parts for your 2020 Audi Q5-Drive belt

2020 Audi Q5 drive-belt: what it does and how to look after it

Yes, a drive-belt is fitted to the 2020 Audi Q5. Technical sources including Audi’s factory repair information (erWin) for the Q5 (FY platform) list removal and installation procedures for the Poly V-belt/serpentine belt on the 2.0 TFSI (EA888) and 3.0 TFSI (EA839) engines, and the Audi service schedule tables for this model include “ribbed V-belt — check.” Audi’s parts catalogue likewise shows a multi‑ribbed accessory belt, automatic tensioner and idler pulleys for these engines.

It’s worth clearing up a common mix‑up: the Q5’s engines use timing chains internally, the drive-belt discussed here is the external accessory belt. Its job is to spin the gear that keeps daily driving comfy and dependable under the bonnet.

On a 2020 Q5, the drive-belt typically powers:

• The alternator, to keep the battery charged and electrics happy
• The air‑conditioning compressor, for chilled air on sweltering days
• On some variants, additional ancillaries, some engines use an electric coolant pump, others may run it by belt
• On certain market variants with mild‑hybrid tech, a belt‑driven starter‑generator

As part of routine servicing, the belt should be inspected for condition and correct tension. A healthy belt has clean, even ribs with no glazing, cracking or frayed edges, and it runs smoothly without squeaks. The automatic tensioner and idlers should also be checked for smooth, quiet operation and proper alignment.

Practical advice for owners:

• Ask for a belt and tensioner check at each service interval
• Replace the belt if there are cracks, missing rib sections, heavy glazing, contamination from oil/coolant, or persistent noise
• If replacing the belt, it’s smart to renew the tensioner and any noisy idlers at the same time
• Belts age with heat and kilometres, many workshops suggest proactive renewal around the medium‑to‑high kilometre mark or 6–8 years, but always follow the factory schedule and inspection findings

Warning signs worth a quick visit to the workshop include chirps or squeals (especially on cold start or in the wet), intermittent battery/charging warnings, air‑con performance dropping at idle, visible belt wear, or a fluttering/wobbling tensioner. For Q5 variants with a belt‑driven starter‑generator, belt condition is even more critical because it handles extra load. A quality OEM‑spec multi‑rib belt fitted by a technician who torques and routes it to the factory procedure will keep everything turning sweetly for Aussie and Kiwi conditions.

Popular questions about the 2020 Audi Q5 drive-belt

Does the 2020 Audi Q5 have a timing belt or a chain?
The 2020 Q5 engines use timing chains inside the engine. The “drive-belt” here is the external serpentine/accessory belt that drives the alternator, air‑conditioning compressor and other ancillaries. They’re separate systems with different maintenance needs.

How often should the drive-belt be replaced on a 2020 Q5?
Audi specifies inspection in the regular service schedule and replacement based on condition. Many workshops recommend proactive replacement at higher kilometres or 6–8 years as a rule of thumb, but the correct call is made on inspection for wear, noise or contamination, and by following the factory guidance for your engine code.

What are the symptoms of a worn drive-belt or tensioner?
Common clues include squealing or chirping (especially on start‑up), flickering battery/charging warnings, weak air‑con at idle, visible cracks or frayed ribs, and a shaky tensioner. If a coolant pump is belt‑driven on your variant, overheating can also appear—pull over safely and get it checked.
