Parts for your 2009 Audi Q5-Drive belt

2009 Audi Q5 drive-belt: what it does, and when to replace it

Based on Audi technical sources—including the Audi ElsaWin repair manuals and the ETKA parts catalogue for the 8R Q5 (2009), as well as Audi Self‑Study Programmes for the CAEB 2.0 TFSI, CALA 3.2 FSI, and CCWA 3.0 TDI engines—the 2009 Audi Q5 is fitted with a poly‑V auxiliary drive belt (serpentine belt). These sources show the belt driving the alternator, air‑conditioning compressor and, on early Q5 models with hydraulic steering, the power steering pump. They also note these engines use timing chains for camshaft drive, so the “drive‑belt” here refers to the accessory/serpentine belt, not a timing belt.

The drive‑belt’s job is straightforward but critical: it spins the alternator to keep the battery charged, runs the A/C compressor for cabin comfort, and turns the power steering pump on models so equipped. If the belt slips or fails, owners can see warning lights, heavy steering, a flat battery, or no cold air—none of which is fun on a hot arvo.

For servicing in Australia and New Zealand conditions, the belt is best inspected at every routine service (about every 12 months or 15,000 km). There’s often no fixed replacement interval from Audi for the accessory belt, but many technicians treat 90,000–120,000 km or around 6–8 years as a sensible window, replacing earlier if any wear shows. On higher‑kilometre Q5s, it’s smart to replace the belt tensioner and idler pulleys at the same time to keep things quiet and reliable.

• Common wear signs: cracking, glazing, fraying, missing ribs, or belt “dust”.
• Noises: chirps/squeals on start‑up or with A/C load often point to belt or tensioner issues.
• Operational clues: battery light, heavy steering, or weak A/C can indicate belt slip.

• Use the correct 6‑rib (6PK) belt specified for the exact engine and options, lengths vary by engine code and equipment.
• Check pulleys and tensioner for smooth rotation and alignment, replace if rough or wobbly.
• Keep the belt free of oil or coolant, if contaminated, replace rather than clean.
• Follow the factory belt routing diagram (often on a decal or in ElsaWin) and set the tensioner correctly.

Whether it’s the 2.0 TFSI, 3.2 FSI, or 3.0 TDI, the 2009 Q5 relies on a healthy auxiliary belt system to keep charging, cooling and steering on song. A quick check at each service saves headaches later.

Does the 2009 Audi Q5 have a timing belt or a chain?

The main engine timing on 2009 Q5 petrol (2.0 TFSI, 3.2 FSI) and diesel (3.0 TDI) engines is by timing chain, not a timing belt. Separate to that, the vehicle does use an auxiliary drive (serpentine) belt to run the alternator, A/C and, on many models, the power steering pump.

How often should the 2009 Q5 drive‑belt be replaced?

Inspect the belt at every service (about 12 months/15,000 km). Many workshops replace it around 90,000–120,000 km or 6–8 years, sooner if there’s any cracking, noise, glazing or contamination. Tensioner and idlers are commonly renewed with the belt on higher‑kilometre vehicles.

What size drive‑belt does a 2009 Q5 use?

It’s a 6‑rib (6PK) poly‑V belt, but the exact length depends on the engine code and fitted equipment (e.g., A/C and steering configuration). The correct part number is confirmed against the VIN in Audi’s parts system (ETKA) to avoid fitment dramas.
