2009 Audi A4 2.0L Diesel · WR09 DCU

A pattern of progressive front‑suspension wear and a recurring centre‑exhaust clamp split defines this 2009 Audi A4’s recent MOT history; the July 2026 test still recorded a pass but listed several advisories for the near‑side lower suspension arm ball‑joint dust cover, both front upper arm pins or bushes, and a split exhaust clamp, alongside a tyre that is close to the legal wear limit on the off‑side rear. Earlier tests show the same upper‑arm bush wear reappearing in 2025 and a similar exhaust‑clamp advisory, indicating that these issues have persisted rather than been fully resolved, while no outright failures have been recorded. At 189,209 mi the vehicle averages roughly 11,100 mi per year, a mileage rate that sits within normal expectations for a seventeen‑year‑old saloon. The MOT record shows annual testing with no significant gaps, suggesting the car has been driven consistently rather than sitting idle for extended periods. Continuous mileage of this magnitude will naturally advance wear on consumables such as suspension bushings, CV joints, brake components and tyres, meaning that the observed advisories are consistent with the vehicle’s usage profile. The front‑suspension arm wear warrants close inspection on a test drive: feel for any looseness or knocking when traversing bumps, listen for clunking that may indicate a deteriorated ball‑joint dust cover or excessive play in the upper arm pins. Examine the steering response for any wandering or pull, and check that the front wheels remain true without uneven tyre wear, which could signal that the worn bushings are beginning to affect alignment. A visual check of the lower‑arm dust cover for cracks or missing material will help gauge the immediacy of replacement. The split centre‑exhaust clamp can produce a noticeable rattling noise at idle or under acceleration and may allow exhaust gases to escape before the catalytic converter, potentially affecting emissions compliance. Inspect the underside for any escaping fumes and verify that the clamp has been reseated or replaced. The oil‑leak advisory from 2025 should be followed up by confirming the source—whether a valve cover gasket, oil filter housing or another seal—and monitoring oil level between fills. The severely deteriorated CV boot noted in 2019 should be examined for grease residue or torn edges, as a compromised boot can lead to joint failure and a characteristic whine during cornering. Finally, the rear tyre’s edge wear suggests the need for immediate replacement and a check of the rear suspension geometry to prevent premature wear on a new set.
