Parts for your 2019 Audi Q5-Drive belt

2019 Audi Q5 drive-belt: what it is, what it does, and when to sort it

Yes, a drive-belt is used on the 2019 Audi Q5. Audi’s workshop literature for the Q5 (FY) platform lists a Poly V-belt/serpentine belt under Rep. Gr. 13 – Poly V-belt, and the Audi Self‑Study Programme for the 2.0‑litre TFSI EA888 Gen.3B (MLB evo) details a belt‑driven alternator and A/C compressor. The Q5’s engine timing is by chain, not a timing belt, but the accessory drive-belt is very much part of the package. Audi’s scheduled maintenance guidance for Q5 FY models also calls for periodic inspection of the ribbed belt at routine services.

On a 2019 Audi Q5, the drive-belt is the quiet achiever up front, looping around pulleys to spin key accessories whenever the engine’s running. It:

• Drives the alternator to keep the 12 V battery charged and the electrics happy
• Turns the A/C compressor so the cabin stays cool on hot Aussie and Kiwi days
• Works with a spring-loaded tensioner and idler pulleys to keep everything tracking straight

Because power steering is electric on this model, there’s no belt for that, and the timing chain tucked inside the engine handles valve timing separately. That’s a handy distinction when talking belts on a Q5.

For servicing, the belt is generally replaced on condition rather than at a fixed kilometre figure. A good rule of thumb in Australia and New Zealand is to have it inspected at every service (typically every 12 months or 15,000 km). Many owners choose preventative replacement somewhere around 90,000–150,000 km or 6–8 years, especially if the vehicle sees heat, dust, or lots of short trips. Always follow the owner’s manual and workshop guidance.

Signs it’s time to act:

• Chirping or squealing from the front of the engine, especially on cold start or when the A/C kicks in
• Cracks, fraying, glazing, missing ribs, or rubber dust around the pulleys
• Battery warning lamp, dim lights, or weak charging (alternator not being driven properly)
• A/C going warm at idle

Best practice when replacing the belt is to check the tensioner and idler pulleys and swap them if there’s play, noise, or roughness. Use an OE-equivalent ribbed belt, stick to the correct routing, and keep oils and coolant off the belt. With the right parts and fitment, the Q5’s drive-belt will do its job for years without fuss.

Popular questions about the 2019 Audi Q5 drive-belt

Does the 2019 Audi Q5 have a timing belt or a chain?
The 2019 Q5 uses a timing chain for cam timing inside the engine. The external drive-belt (serpentine belt) is separate and runs accessories like the alternator and A/C compressor.

How often should the drive-belt be replaced?
It’s inspected at regular services (about every 12 months/15,000 km). Replacement is usually on condition, many owners opt for preventative replacement around 90,000–150,000 km or 6–8 years, depending on wear and driving conditions.

What are the warning signs of a worn belt?
Squeals or chirps, visible cracks or glazing, rubber dust, a flickering battery light, or the A/C blowing warm at idle are all cues to have the belt and tensioner checked promptly.
