2020 Audi A4 Technik 35 TDI S-A 2.0L Diesel · LL20 HHT

The vehicle most recently passed its DVSA MOT test on 30 September 2025, with the only issues being advisories relating to wear in the front lower suspension arm rear bushes on both the nearside and offside. While the test result itself is a pass, the appearance of suspension advisories at this mileage and age represents a developing maintenance concern rather than a clean bill of health. The previous test history indicates a generally stable but slightly worsening trend, as the 2023 test was completely clear with no advisories, whereas the 2024 cycle required a failed retest for headlamp aim before passing, accompanied by advisories on all four tyres being worn close to the legal limit. The combination of a tyre advisory set followed by a suspension component advisory a year later suggests that wear items are beginning to surface as the vehicle accumulates mileage, which is normal for an Audi A4 of this age, but the prospective buyer should be aware that further deterioration of these items is likely. With 57,741 miles recorded over approximately six years, this A4 is averaging around 9,600 miles per year, which is broadly typical for a modern diesel executive saloon and indicates consistent regular use rather than extended periods of standing or unusually high motorway accumulation. Regular use of this nature is generally favourable for mechanical longevity, as it tends to prevent issues such as brake disc corrosion from lack of use, flat spots on tyres, and oil seal drying out. The mileage gap between tests also appears consistent with annual servicing and MOT cycles, and there is no evidence of a dramatic mileage jump or a long period of dormancy that would raise separate concerns about standing-related degradation. The most significant item to investigate further is the advisory on the front lower suspension arm bushes, which were noted as worn but not yet resulting in excessive movement. This is a common wear point on vehicles of this age and mileage, and the bush condition will only progress from here. On a test drive, the buyer should listen carefully for any clonking or knocking from the front suspension, particularly when traversing speed bumps, potholes, or uneven road surfaces, and pay attention to any vagueness or delay in steering turn-in. Uneven or feathered tyre wear on the front wheels would also indicate that the bushes are no longer holding the correct geometry. Given that the 2024 advisories flagged the tyres as worn close to the legal limit on the edges, it is reasonable to expect that a further set of tyres has been fitted since, and the buyer should verify the age, brand, and tread depth of the current set, as well as confirm whether the front suspension bushes have been inspected or replaced. Beyond the recorded advisories, a vehicle of this vintage warrants attention to several age-related items regardless of the MOT outcome. The 35 TDI engine is fitted with a timing belt or chain depending on the specific production date, and the buyer should verify the exact service history to confirm whether the manufacturer scheduled interval has been observed. Diesel particulate filter condition should be considered given the relatively low annual mileage, as short journeys can lead to incomplete regeneration cycles. Brake discs should be physically checked for lipping and corrosion, even though regular use generally mitigates this, and the 12V battery should be tested for holding charge, as modern vehicles with extensive electronics can suffer premature battery depletion. Finally, confirmation of a complete main dealer or specialist service book, including recent brake fluid, coolant, and transmission oil changes in line with calendar-based intervals, will provide the strongest reassurance that this A4 has been maintained to the standard commensurate with its premium billing.
