2009 Audi A6 2.0L Diesel · W40 AAA

A pattern of accumulating front-end suspension wear is the defining mechanical characteristic of this 2009 Audi A6, evidenced by a sequence of advisories appearing in the most recent two MOT tests after a long run of clean passes. The vehicle passed its test on 2026-08-07, but the examiner recorded advisories on both nearside and offside front upper suspension arm pins or bushes, indicating wear that has not yet resulted in excessive movement. This follows a 2025-08-04 advisory noting slight play in the nearside front track rod end ball joint. Prior to these two tests, the vehicle had recorded five consecutive passes from 2020 through 2024 with no advisories at all, meaning the suspension-related wear is a recent and developing concern rather than a long-standing issue. The shift from a clean record to multiple advisories concentrated on the front suspension within the space of a year warrants close physical inspection. With 230,740 miles recorded over approximately 17 years, the vehicle has averaged around 13,573 miles annually, which is a notably high accumulation for a car of this vintage. This level of sustained use places considerable mechanical demand on consumables and wear components, particularly the suspension, braking system, engine and gearbox internals, and rubber bushes throughout the chassis. There are no extended gaps between tests in the recorded history, with the vehicle appearing annually since 2019, suggesting it has remained in regular service rather than being laid up. High annual mileage combined with the recent emergence of suspension advisories is consistent with components reaching the natural end of their service life, as parts such as control arm bushes, ball joints, and track rod ends are subject to progressive wear on heavily used vehicles. A prospective buyer should pay particular attention to the front suspension components that have been flagged. During a test drive, listen for any knocking or clonking noises from the front end when traversing speed bumps, potholes, or uneven road surfaces, as this would suggest the worn upper control arm pins or bushes are approaching the point of excessive play. Check for uneven or accelerated wear on the front tyres, which can indicate worn suspension geometry or deteriorating bushes, and pay attention to any vagueness, wandering, or instability in the steering, particularly over broken surfaces, which would suggest the track rod end play noted in 2025 has progressed. Visually inspect the front control arms, bushes, and ball joints for any perishing, cracking, or oil contamination, and check the front brake discs and pads for wear given the high overall mileage. Beyond the specifically flagged items, the high accumulated mileage makes it sensible to scrutinise components that typically deteriorate with prolonged use. Inspect the exhaust system for corrosion or blowing joints, check the engine and gearbox for any signs of oil leaks or seepage, and examine the rear suspension and subframe mounting points for corrosion given the vehicle's age. On the test drive, listen for any clonking from the rear, vibrations through the steering wheel, or pulling under braking, and verify that the gearbox changes smoothly through all gears. Given the recent cluster of front suspension advisories following a long clean record, budgeting for replacement of the front upper control arms, bushes, and possibly the track rod end in the near term would be a prudent consideration.
