2015 Audi A4 2.0L Diesel · KY13 AAA

The vehicle passed its most recent DVSA MOT test on 19 June 2025, although a structural advisory was issued regarding corrosion to the rear sub-frame, which was noted as not seriously weakened at the time of inspection but warrants careful monitoring as the condition can progress between tests. An additional advisory recorded a child seat fitted to the nearside rear which prevented full inspection of the adult belt; this is an administrative note rather than a mechanical defect but should be verified during a physical viewing. The broader test history shows a pattern that is broadly stable but with a gradual accumulation of wear-related advisories over time. Earlier failures in 2021 and 2024 addressed suspension component leakage, tyre integrity, and windscreen damage respectively, and subsequent passes have largely been clean aside from minor items, suggesting the vehicle has been maintained to a roadworthy standard but is now entering a phase where component age and corrosion are beginning to feature more prominently in the inspection record. With 99,822 miles recorded over approximately 11 years, this Audi A4 is running at an average annual mileage of around 9,075 miles, which sits comfortably within typical parameters for a vehicle of this age and class. There are no significant gaps in the MOT history that would suggest prolonged periods off the road, and the mileage progression appears consistent with regular use. This level of usage means the vehicle has not been excessively worked, which is beneficial for the longevity of the drivetrain and engine internals, but it also means that some wear-related advisories relating to suspension, braking, and tyre components are entirely consistent with a car that has covered a full lifetime of normal road exposure. The MOT records do not indicate any exceptionally rapid mileage accumulation that might point to previous commercial or high-intensity use. Reviewing the defect history, several recurring themes warrant close attention during a pre-purchase inspection. The rear shock absorber failure in 2021 and the related advisory in 2020 concerning light oil misting on the offside rear unit suggest that the rear suspension may have been partially renewed at that point; a prospective buyer should verify the age and condition of the remaining dampers, listen for any knocking or clonking over uneven surfaces on a test drive, and check for signs of fluid seepage around the rear strut bodies. The front brake discs were flagged as worn and pitted in 2021, and while this was advisory at the time, pitted discs tend to worsen with continued use, potentially causing brake shudder under heavy application or visible scoring on the disc surface, so a thorough inspection of brake disc thickness, run-out, and pad life is strongly recommended. The nearside rear tyre that failed in 2024 for a deep cut highlights the importance of examining all four tyres for sidewall damage, tread depth, and even wear patterns, particularly given the front tyres have previously shown edge wear consistent with potential tracking misalignment or worn suspension bushes. Given the vehicle's age and accumulated mileage, attention should also be directed towards areas that MOT testing does not fully cover but which are critical for a car of this vintage. The rear sub-frame corrosion advisory should be physically inspected, ideally with the vehicle raised, to confirm there is no progression towards structural weakening, particularly around mounting points and mounting bush interfaces. The timing chain, turbocharger oil feed pipes, and DSG or multitronic transmission mechatronics seals are known age-related concern areas on the Audi B9 platform and warrant specific questioning of the service history. Additionally, given that this is an eleven-year-old vehicle, time-based servicing items such as brake fluid, coolant, and automatic transmission fluid should be verified as recently renewed regardless of mileage, as these fluids degrade through age rather than use alone. The 12V battery should be tested for state of health, as units of this age frequently suffer reduced cranking performance, and all tyres should be checked for sidewall perishing or cracking from age even if tread depth remains adequate. A full service history stamp verification, particularly confirming regular oil and filter changes at appropriate intervals, will provide the strongest indication of how this vehicle has been mechanically maintained throughout its life.
