2014 Audi A6 2.0L Diesel · AM59 HAS

A pattern of structural and brake-related advisories has built steadily across this Audi A6's MOT record, and the 2026 test on 22 June confirms that corrosion is now the defining concern. The most recent pass flagged an offside front Macpherson strut corroded but not seriously weakened, alongside rear sub-frame corrosion, also not seriously weakened at this stage. These items sit at the borderline of MOT pass criteria and warrant close physical inspection, as corrosion described in this manner tends to progress between tests, particularly on a vehicle operating in a UK climate where road salt is prevalent. The earlier record is largely clean of structural concerns, with the 2022 and 2021 tests instead highlighting rear brake fluctuations, rear disc wear, and a light oil mist on the nearside rear shock absorber. The absence of any recorded failures across eight tests is a positive indicator of overall roadworthiness, but the emerging corrosion pattern is the most significant mechanical risk for a prospective buyer to verify in person. The mileage profile is broadly consistent with typical use for a 2014 vehicle, averaging roughly 9,500 miles per year across the recorded period, with no obvious gaps in testing history or sudden odometer jumps that might suggest irregular use. The annual accumulation between tests is steady, indicating the vehicle has remained in active service rather than being laid up for extended periods. At 114,143 miles, the car sits in a usage bracket where suspension components, bushes, and brake wear items commonly require attention, and the recorded advisories align with that expectation. The consistent yearly testing pattern also means there is a reliable, continuous DVSA history to draw conclusions from, with no long absences that could mask deterioration. For a prospective buyer, the priority on inspection is the underside structure, particularly the rear sub-frame and the offside front strut area flagged in 2026. On a ramp or over a pit, check for any flaking, scaling, or perforation of the sub-frame and surrounding mounting points, and examine the strut body for bubbling paint, white deposits, or flaking metal that would suggest the corrosion has advanced beyond what was visible to the tester. On the road, listen for clonks or knocks from the front suspension over speed humps and uneven surfaces, as a compromised strut top or corroded mount can produce audible impact noises even when static examination looks marginal. Pay attention to steering response and any vagueness through the wheel, which could indicate worn strut bearings associated with the corroded damper assembly. The rear brake history deserves a focused assessment, given the recurring fluctuating service brake advisories on both sides in 2021 and 2022, combined with pitted or scored rear discs noted in 2022. On test, expect to feel a variation in braking effort, particularly under moderate pedal pressure, where the rear callipers may bind or the handbrake mechanism may not fully release, causing uneven pad wear. A thermal check of the rear wheels immediately after a drive can reveal a hot hub relative to the front, pointing to a seizing calliper. The nearside rear shock absorber oil misting noted in 2021 should also be checked for progression, visible as a damp film or streak on the body of the unit, and any uneven tyre wear, particularly on the front, should be investigated for tracking or suspension geometry issues. Given the vehicle's age and mileage, a thorough inspection of the CV gaiters, exhaust mounting points, and all underbody brake and fuel lines for corrosion would be a sensible final measure before purchase.
