Parts for your 2008 Audi Q5-Drive belt tensioner

2008 Audi Q5 drive-belt tensioner

Based on Audi factory workshop information (ElsaWin), the Audi electronic parts catalogue (ETKA), and major OEM supplier catalogues from INA/Litens, Gates and Dayco, the 2008 Audi Q5 (Type 8R) is fitted with an automatic accessory drive-belt tensioner across its early engines (including 2.0 TFSI, 3.2 FSI and 3.0 TDI). So yes, a drive-belt tensioner is absolutely relevant on this model.

The drive-belt tensioner on a 2008 Q5 keeps the serpentine belt at the right tension as the belt stretches and the accessories load up. That steady tension helps deliver quiet, reliable drive to the alternator, A/C compressor and, where fitted, the power steering pump. A healthy tensioner stops belt slip and squeal, keeps charging voltage stable, and protects bearings in the accessories by damping vibration and belt flutter.

As part of routine servicing, it’s smart to eyeball the tensioner and belt at every service. Look for a shaky or misaligned pulley, a weak or “lazy” arm return, or any signs of the pulley bearing grumbling. In Aussie and Kiwi conditions, many tensioners last 100,000–150,000 km, but heat, dust and lots of short trips can bring that forward. There’s no set interval—replace on condition, and always consider doing the belt and idler pulleys at the same time. While you’re there, check the alternator’s overrunning pulley (OAP) and, on some diesels, the A/C stretch belt—both can mimic tensioner faults.

Replacement is straightforward with the right tools. Safely support the vehicle, pop the bonnet, note the belt routing, and use the correct hex or Torx drive to rotate the tensioner and slip the belt off. Spin the tensioner pulley
