2011 Audi A6 2.0L Diesel · AJ60 NFH

A clear pattern of chronic anti-roll bar linkage wear defines this Audi A6's mechanical story, with the components first noted as worn in 2023, flagged again in 2024, and ultimately failing on excessive wear by February 2025 across both nearside and offside front positions. The vehicle returned to the road shortly after on the same date in 2025 with new advisories for damaged rear light units alongside the same recurring registration plate lamp defect. Most recently, the car attended test on 19 February 2026 where it initially failed on a non-functioning offside front position lamp and headlamp aim screening failure, before passing the same day with stone chip windscreen damage and the continuing registration plate lamp issue. The advisory raised against the front subframe for corrosion not seriously weakened on this latest pass introduces a structural concern worth monitoring given the vehicle's age, though the front suspension bushes appear to have been addressed following the 2025 failure. The rear brake disc wear noted in 2023 and 2024 does not appear in the most recent record, suggesting replacement has occurred, while the centre exhaust sleeve leak flagged in 2023 has also dropped out of subsequent advisories. With 145,760 miles recorded against a 2011 manufacture date, this A6 has covered approximately 9,717 miles annually, which sits within typical expectations for a vehicle of this age and avoids the elevated wear rates associated with high-mileage examples. There are no significant gaps in the testing history, with annual entries from 2022 through 2026, suggesting continuous use rather than extended periods of standing. The mileage accumulation has been steady rather than abrupt between tests, indicating the vehicle has remained in regular service. At this accumulated mileage on a fifteen-year-old Audi, attention to major service items such as timing chains, turbochargers (if applicable to the engine variant), automatic transmission fluid and gearbox mechatronics would be prudent, though none of these items fall within the scope of MOT testing and cannot be assessed from the available records. The most pressing mechanical concern for any prospective buyer remains the front anti-roll bar linkage wear pattern, which progressed from advisory in 2023 to outright failure in 2025, demonstrating that wear can advance quickly between tests. On a road test, listen for clonking or knocking noises from the front suspension over uneven surfaces, particularly speed humps and potholes, and feel for vagueness or imprecise body control during direction changes. Inspect the front subframe closely for any progression of corrosion beyond the light surface rust noted, paying particular attention to mounting points, longitudinal sections, and any areas where road salt accumulates, as subframe corrosion on C6 and C7 platform Audis of this vintage can develop rapidly once initiated. Lift any floor mats and check the footwells for moisture ingress, as perished door seals and blocked sunroof drains on this generation can cause water staining on interior carpets and corrode underbody wiring. The braking system warrants careful physical inspection despite the disc wear advisories appearing to have been resolved. On test, listen for any scraping or grinding from the front calipers during low-speed manoeuvres, which could indicate a seized slider mechanism, and feel for any pulling to one side under firm braking which might suggest a binding caliper or uneven pad wear. Verify that the offside rear registration plate lamp functions correctly, as it has failed under the minor defect category at multiple consecutive tests, and inspect both rear light units for cracks or moisture ingress given the damage advisories recorded in 2025. Check exhaust condition thoroughly, particularly the centre section, and listen for any blowing noises on the over-run which would indicate a failed gasket or flexi-joint. Finally, examine the headlamp aim adjustment mechanism, as the 2026 fail noted excessive beam height on the nearside unit, which on this platform often relates to failed levelling motor linkages or simply requires manual re-aimment, but should be confirmed as corrected rather than masked.
