2008 Audi Q5 2.0L Diesel · OV58 OUC

The dominant mechanical story on this 2008 Audi Q5 centres on the front suspension, where the 2024 test cycle produced the most serious findings in the recorded history. On 3 July 2024 the vehicle failed on a nearside front lower suspension arm ball joint recorded as excessively worn, accompanied by advisories across both front lower arm and both front upper arm rear bushes indicating wear not yet resulting in excessive movement. A pass was issued the same date, but the simultaneous fail and pass confirm a repair or component replacement was carried out before the pass certificate was issued. Aside from this suspension cluster, the remainder of the seven-test record is relatively benign, with single advisories for front tyre wear in 2022, a rear brake pad thinning note in 2021, and a nearside rear tyre advisory in 2019. The 2023 and 2020 tests and the 2018 test were passed with no defects recorded, indicating the suspension deterioration became acute in the final recorded cycle rather than representing a long-standing pattern of test failures. The presence of a child seat advisory in 2024 is procedural rather than mechanical and does not reflect component condition. Mileage accumulation on this vehicle sits close to the typical curve for an 18-year-old car, with 177,074 recorded miles implying around 9,837 miles per year over its life. There are no extended gaps between annual tests that would suggest prolonged off-road storage, and the testing cadence from 2018 through 2024 is consistent with regular use. For a high-mileage Q5 of this vintage, this level of annual running means consumables and suspension components have been worked consistently rather than allowed to deteriorate through standing, but it also places cumulative demand on the front axle components, drivetrain mounts and rear brake system. The repeat advisories on front tyres and the thinning rear brake pads in earlier tests are consistent with a vehicle that has covered meaningful distance between annual checks. A prospective buyer should treat the 2024 suspension entry as the central inspection priority. The lower arm ball joint that caused the failure is a load-bearing item connected to the front MacPherson-type strut assembly, and the four accompanying bush advisories suggest the front axle was on the edge of its service life. On a test drive, listen for clonking or knocking from the front end over speed humps and uneven B-road surfaces, particularly under load through corners, and feel for imprecise steering response, vagueness around the straight-ahead, or uneven tyre wear patterns on the inner or outer front edges that would confirm ongoing bush degradation. With 177,000 miles covered, the rear brake pads flagged thin in 2021 will almost certainly have been replaced, but the calipers, discs and handbrake mechanism should still be checked for binding, hot spots after driving, and uneven disc wear lipping. Beyond the suspension, the advisory history points to a few additional areas worth examining on inspection. Front tyres were reported worn to the legal limit on both sides in 2022, so confirm current tread depth, manufacturing date, and whether the wear pattern is even, as uneven shoulder wear on a Q5 of this mileage can indicate suspension geometry issues that have not been fully resolved. Lift the vehicle and inspect the subframe, suspension arms, brake pipes and fuel lines for corrosion, paying particular attention to the rear arches and underbody seams typical of early Q5s exposed to winter road salt. Finally, check for oil misting or seepage around the cam chains, turbo oil feed lines and the rear main seal, which are common high-mileage concerns on the earlier 2.0 and 3.0 TFSI and TDI engines, and verify that the service history independently confirms timely fluid and filter changes irrespective of the MOT outcome.
