2017 Audi A6 2.0L Diesel · YP67 HTZ

Against a recorded 126,222 miles accumulated over nine years of service, this 2017 Audi A6 has delivered an uninterrupted sequence of clean MOT passes, the most recent being a defect-free test on 8 October 2025. Across the four consecutive annual examinations on file from 2023 onwards, no advisories, minor defects, or component failures have been recorded by the DVSA tester, and a separate test entry dated the same day as the January 2023 pass also carries no recorded defects. The notable point of interest here is the 2023-01-26 FAILED entry that sits alongside a PASSED result on the same date; with no defect information associated with that failure, it is most likely a recorded administrative event or a presentation issue at the station rather than a genuine mechanical refusal, though a prospective buyer should treat the paper trail as worth clarifying with the seller. The overall roadworthiness picture is therefore one of consistent compliance at test time, with no chronic advisories pointing toward progressive deterioration in any single subsystem. The mileage profile is the dominant mechanical variable on this car. At roughly 14,000 miles per year against a typical UK average of around 7,500, this A6 has been worked substantially harder than average, doubling the expected consumption of braking materials, tyres, and drivetrain components. The annual test history shows entries in January 2023, January 2024, October 2024, and October 2025, which implies the vehicle has been inspected at intervals consistent with continuous use rather than any extended off-road storage. With high-mileage service intervals already well into the second cycle of major consumables, items such as the dual-clutch or torque converter automatic transmission fluid, engine oil and filter, spark plugs on the petrol variants, and the auxiliary belt and tensioner will all be approaching replacement points relative to manufacturer schedules rather than calendar time. Given the mileage but the absence of any flagged suspension, brake, or corrosion advisories on the MOT record, a prospective buyer should treat the test outcome as confirmation of pass-stage compliance only and not as evidence of underlying component health. On a road test, listen carefully for any clonking or knocking from the front suspension over uneven surfaces, as the multi-link front geometry common to this generation of A6 is known to wear the lower wishbone rear bushes and anti-roll bar drop links at high mileage; any vagueness in the steering around the straight-ahead or a slight pull would warrant further investigation. The braking system should be evaluated for any judder through the pedal under firm application, which on a high-mileage Audi of this era frequently points to disc warping rather than pad wear, and the car should be held on a slight incline with the handbrake released briefly to confirm the electronic parking brake is holding without warning lights on the dashboard. Inside the engine bay, the high-mileage drivetrain warrants a cold-start inspection if possible, as the 2.0 TFSI and 3.0 TDI engines fitted to this model can develop oil misting around the cam chain area or turbo oil feed pipes well before any external seepage becomes visible on a ramp. With over 126,000 miles recorded, timing chain stretch on the petrol units and turbocharger actuator wear on the diesels are realistic concerns that would not necessarily be surfaced by a routine MOT. A compression or cylinder leakage check through a specialist, alongside a service history audit confirming the long-life oil and filter changes have actually been performed at the correct intervals rather than stretched to economise, would be the most prudent due diligence before committing to purchase. The clean MOT paper trail is reassuring, but on a high-mileage executive vehicle of this age, the absence of advisories simply reflects a tester confirming the legal minimum on the day rather than a comprehensive mechanical condition report.
