2010 Audi A6 2.0L Diesel · BU58 ALS

The most recent DVSA examination on 26 January 2022 resulted in a PASS classification, indicating the vehicle met the minimum statutory roadworthiness requirements at the time of test. However, the overall maintenance trend warrants careful scrutiny. The earlier January 2021 test produced a Dangerous failure for tyres below the 1.6mm tread threshold on both front wheels, alongside Major defects for an incorrect colour direction indicator and a significantly reduced front position lamp, suggesting genuine lapses in routine servicing and pre-test preparation. That same date also carries a PASS entry, indicating a quick return to compliance after the failures were rectified. While the 2022 pass is positive, the absence of any MOT recorded since January 2022 suggests the vehicle may have covered nearly four years without statutory inspection, which is a significant concern for a prospective buyer and warrants an immediate pre-purchase check. With approximately 197,256 recorded miles over a 16-year life, this A6 has averaged around 12,328 miles per year, which is considerably higher than typical private-car usage and points to long-distance motorway commuting, commercial use, or extended tourer duties. The gaps in the recorded history, particularly the long interval between the 2019 test and the 2021 re-test, combined with the absence of any recorded examinations after January 2022, are notable. High-mileage vehicles of this age demand close attention to turbocharger wear, dual-mass flywheel condition (on manual variants), timing chain service history on the larger petrol units, automatic gearbox fluid history, and potential oil consumption from worn valve guides or piston rings. The elevated annual mileage also accelerates wear on suspension components, engine mounts, and drivetrain flex discs. The 2022 advisory for rear brake pads wearing thin suggests those pads may now be due for replacement, and on a test drive the buyer should listen for any grinding or squealing from the rear axle and verify there is no pulling under braking. The advisory for a slightly noisy offside front wheel bearing is a classic precursor to failure, often progressing to a louder drone that changes with cornering load; immediate replacement of the bearing hub assembly is prudent, particularly given the higher than average mileage. The 2018 advisories for front tyres worn on the inner edge are a strong indicator of tracking misalignment or worn front suspension bushes, wishbone arms, or anti-roll bar links, all common failure points on the C6 platform. A test drive over uneven surfaces should be conducted listening for clonks or knocking from the front suspension, and the inner tread shoulders of any current tyres should be physically inspected for feathering. Given the vehicle's age and the likely extended standing periods implied by the MOT gaps, a prospective buyer should also conduct age-related checks beyond the DVSA record. Tyre sidewalls should be examined closely for cracking or perishing, as tyres older than six years from their DOT date suffer rubber degradation regardless of tread remaining. Brake calipers, particularly the rear electronic parking brake mechanisms common to this model, are prone to seizing from corrosion during periods of inactivity, so each corner should be jacked to confirm the calipers release cleanly and the discs spin freely without roughness. The 12V battery should be load-tested, as a 16-year-old original or replacement unit is well past its reliable service life. Coolant, brake fluid, and power steering fluid all degrade regardless of mileage and should be assessed for condition and date of last renewal, with a brake fluid test strip confirming water content below the contamination threshold. Finally, the service book should be thoroughly examined to confirm regular oil and filter changes at appropriate intervals, and any evidence of cambelt or timing chain replacement verified, as neglect of these on a high-mileage Audi V6 or V8 unit can result in catastrophic engine damage.
