2007 Audi A6 SE TDI 2.0L Heavy oil · ND57 ABU

A consistent pattern of roadworthiness compliance defines this nineteen year old Audi A6 SE TDI, with the vehicle securing passes on four of its last five recorded tests. The 2025-06-15 test returned a clean pass with no advisories or defects recorded, while the only failure on the record came just eleven days earlier on 2025-06-04 with no defects listed, suggesting a minor issue was rectified between the two attempts or a refusal-related item was addressed. The earlier history is equally reassuring, with passes at 2024-05-13, 2023-01-24, and 2022-01-04, the latter carrying only two minor advisories relating to rear brake pad wear and a deteriorating rear number plate. The overall trajectory is one of stable mechanical condition with no recurring advisories, no structural corrosion flags, and no repeat component concerns, which is a positive indicator for a diesel saloon approaching two decades of service. Against an age of nineteen years, the recorded mileage of 116,405 miles equates to an annual accumulation of roughly 6,127 miles, which sits firmly within typical parameters for a UK-driven diesel executive car of this vintage. There are no notable gaps in the testing history that would suggest extended periods off the road, nor are there any sudden mileage jumps that might indicate clock irregularities or rapid accumulation between tests. This steady, moderate usage pattern suggests consistent operation rather than long lay-ups that could have led to moisture ingress in brake lines, exhaust corrosion from condensation, or seized brake calipers from infrequent use. Mechanically, this kind of consistent running tends to preserve diesel components such as the turbocharger, dual mass flywheel, and EGR valve, though these high-mileage diesel-specific items remain time-related wear items regardless of usage intensity. Given the 2022 advisory noting rear brake pads wearing thin, particular attention should be paid to the rear braking system during inspection. On a test drive, listen for any scraping or grinding noise when applying the brakes lightly, and check whether the rear calipers are binding by feeling for excessive heat at the rear wheels shortly after driving. Uneven pad wear on the rear axle could indicate a sticking slider pin or a partially seized caliper mechanism, both common on ageing Audi platforms. Inspect the rear brake discs for lipping or scored surfaces, as the 1.1.13 advisory reference relates to pad condition that, if ignored, would have progressed to disc damage by now. Pedal feel should be firm and progressive without excessive travel or sponginess, which would point to hydraulic concerns or perished brake fluid. Beyond the flagged brake items, the test drive should focus on the typical weak points of the C6 generation A6, including front suspension components, engine oil leaks, and the automatic or multitronic transmission behaviour. Listen for clonking or knocking from the front suspension over speed humps and uneven road surfaces, paying particular attention to the lower control arms, anti-roll bar bushes, and top mount bearings, which are known wear items on this platform. Inspect the engine bay and undertray for any signs of oil misting or weeping from the cam chain tensioner area, turbocharger seals, or the rear main seal, as these are age-related concerns on the 2.0 or 2.7 TDI engines fitted to this model. For automatic variants, ensure the gearbox changes smoothly without hesitation, shudder, or delayed engagement, and verify that the steering is precise without vibration or pulling, which would indicate worn front suspension geometry or tracking issues requiring attention.
