2018 Audi A6 3.0L Diesel · YC68 AAJ

The most recent DVSA MOT conducted on 28 August 2025 returned a Pass with no recorded defects, and the three preceding annual tests also passed without any failures. The only entry of note is an advisory in August 2022 concerning the fitting of the engine cover and under‑tray, which does not constitute a safety defect. This uninterrupted sequence of clean passes indicates a stable maintenance record, with no evidence of deteriorating compliance over the last four years. At 115 063 miles the 2018 Audi A6 has accumulated roughly 14 400 miles per annum, a mileage rate that exceeds the typical average for a vehicle of its age. Such a usage pattern suggests the car has been driven regularly and under a variety of conditions, which accelerates wear on consumables such as tyres, brake pads, discs and suspension components. The relatively high annual mileage also raises the likelihood of progressive fatigue in engine bearings, timing chain tensioners and drivetrain joints, making thorough inspection of these areas essential. When inspecting the vehicle, pay particular attention to the tyre condition: verify tread depth is above the legal minimum, look for sidewall cracking or perishing that can result from age rather than wear, and assess whether wear is even across the set, which would indicate correct wheel alignment and healthy suspension bushes. Examine the front and rear suspension for any looseness, clunking noises over bumps, or excessive play in the control arm and wishbone bushings, as high mileage can precipitate bush wear and coil‑spring fatigue. Inspect the braking system for disc surface corrosion, uneven pad wear, and any signs of caliper binding such as a pulsating pedal or uneven disc thickness, and confirm that the parking brake engages firmly without dragging. Given the vehicle’s eight‑year age, also check the 12 V battery for sulphation or reduced cranking power, especially if the car has spent periods standing idle. Verify that engine oil, coolant and brake fluid have been changed at the recommended intervals; fluid should be clear and free of particulate contamination, as time‑based degradation can occur even with moderate mileage. Finally, confirm that the engine cover and under‑tray are securely fitted and free of rust or oil leaks, and request a full service history to corroborate that timing chain tensioners, spark plugs and other scheduled items have been addressed, ensuring the drivetrain remains reliable for the remaining life of the vehicle.
