Parts for your 2008 Audi Q5-Exhaust mount

2008 Audi Q5 exhaust-mount (hangers): fitment, purpose and servicing

Exhaust-mounts are fitted and relevant on the 2008 Audi Q5 (type 8R). Audi’s factory repair information (erWin/ELSA, Rep. Gr. 26 – Exhaust system, removing and installing) specifies the exhaust is suspended on multiple rubber mounts. The Audi ETKA parts catalogue (Group 253 for Q5 8R) also lists several exhaust mounting rubbers and brackets, with typical VAG hanger part numbers in the 8K0 253 147– series. Major aftermarket catalogues (e.g., Febi Bilstein, Meyle) list “exhaust mounting rubber” for Audi Q5 8R, 2008-on. These technical sources confirm the Q5 uses exhaust hangers to support and isolate the system.

The 2008 Audi Q5 relies on a set of rubber exhaust-mounts (often called hangers) to hold the pipes, resonator and rear muffler in place while soaking up vibration. They keep the system centred in the tunnel, stop metal-to-metal contact with the body, and let the exhaust move a little as the driveline twists. Without healthy mounts, the Q5 can develop knocks over bumps, a rattly start-up, or the tailpipe sitting off-centre in the bumper.

As part of routine servicing, the exhaust-mounts on a Q5 are worth a look each time it’s on a hoist—typically every 12 months or 15,000 km in Australia and New Zealand. Heat, road grime, and coastal conditions harden and crack the rubber over time. By the 8–10 year mark, many original mounts are past their best. Technicians check for perishing, splits, elongation of the holes, and shiny rub marks that suggest contact with heat shields or the rear valance.

Replacement is straightforward but benefits from proper support. With the exhaust safely supported, the old rubbers are pried off the pegs, a rubber-safe lubricant helps. It’s smart to replace mounts in pairs or as a set so the system hangs evenly. After fitting new mounts, the exhaust should be aligned to maintain clearances around heat shields, prop shaft tunnel and rear bumper. If any brackets are bent or corroded, they should be renewed at the same time. Quality OEM or reputable aftermarket rubbers last well, and the parts cost is modest—great value for eliminating thumps and protecting flex joints and welds.

For ongoing care, a quick wiggle test of the muffler while the car is on stands can reveal slack mounts. Avoid petroleum-based sprays on the rubber, if lubrication is needed during install, use a rubber-friendly product. Keeping heat shields secure and intact also reduces heat stress on the new mounts.

• Common symptoms of worn mounts: dull thud on take-off, exhaust drone, off-centre tailpipe, or a metallic rattle at idle.
• Best practice: inspect at every service, replace aged or cracked mounts proactively, and realign the system after fitment.

Popular questions

How many exhaust-mounts does a 2008 Audi Q5 have?
The Q5 typically uses several mounts along the system—commonly one or two near the centre section and two at the rear muffler, with additional brackets as required by engine/trim. Exact count can vary slightly by engine variant and whether it has a single or dual-exit rear section. A technician can confirm the layout on the hoist.

How often should exhaust-mounts be replaced on a Q5?
There isn’t a fixed interval, they’re replaced on condition. In Aussie and Kiwi climates, many original mounts show notable ageing by 8–10 years. Inspect them at every service and replace at the first signs of cracking, hardening, elongation, or if the exhaust is knocking or sitting crooked.

Can worn mounts cause vibration or drone?
Yes. When the rubber hardens or stretches, the exhaust can transmit more vibration into the cabin and resonate at certain revs. Replacing tired mounts usually restores isolation, reduces knocks, and can lessen cabin boom, especially around idle and light throttle.
