2018 Audi A4 2.0L Petrol · KW18 AOC

The 2018 Audi A4 passed its most recent MOT on 30 June 2026 with no defects or advisories recorded, marking two consecutive clean tests after the failure logged at the same appointment in 2024. That earlier failure, combined with the advisory issued at the 2023 test, points to a cluster of rear suspension and brake concerns that have since been rectified, as evidenced by the clean results in 2025 and 2026. The overall maintenance trend therefore appears to be stable and improving, with the rear axle components having been attended to within the last twelve months. However, given that the 2024 test captured significant wear items on the same corner of the vehicle, a prospective buyer should satisfy themselves that the repairs were carried out to a proper standard rather than as a minimal pass, and should keep in mind that the neighbouring suspension components on that axle will have shared the same operating environment and workload. With 74,603 miles recorded over eight years, this A4 has covered approximately 9,325 miles annually, which is broadly typical for a vehicle of its age and class and indicates consistent rather than standing use. There are no large gaps in mileage progression across the recorded MOT tests, suggesting regular driving and therefore a lower risk of issues such as seized brake calipers, perished rubber components, or degraded fluids from inactivity. At this mileage and age, the wear patterns seen at recent tests are broadly expected: brake pads and coil springs typically require attention somewhere between 60,000 and 90,000 miles depending on driving style and road conditions. The annual rate of accumulation is not severe enough to suggest excessive motorway or urban use that would disproportionately shorten the life of clutches, dual-mass flywheels, or turbcharged drivetrain components, though these items should still be inspected given the vehicle's age. The 2024 failure identified a fractured nearside rear coil spring and rear brake pads worn to the wear indicator, both of which are common maintenance items on a vehicle of this mileage rather than indicators of structural concern. Coil spring fracture on the rear axle of an A4 is a well-documented wear pattern, often associated with corrosion at the spring seats accelerating metal fatigue; the advisories from 2023 noting corroded rear coil spring mountings are consistent with this and suggest the front spring seats and top mounts should also be examined for similar deterioration. On a test drive, listen for clonking or knocking from the rear over uneven surfaces, particularly when turning or braking, and watch for the rear of the car sitting unevenly or bottoming out under load. The brake pad replacement should also prompt inspection of the rear brake discs, as worn pads left in contact with the discs for an extended period can cause lipping or corrosion of the disc surface, leading to brake shudder under firm application. Beyond the specific defects in the record, a buyer of this eight-year-old A4 should conduct a thorough age-appropriate inspection. Check all four tyres for sidewall cracking and perishing, as the 2024 advisory on the offside rear tyre shows this is an active concern on this vehicle; budget for a full set if any show similar deterioration, particularly as tyres over five years old can fail MOT on age-related cracking regardless of tread depth. Inspect the exhaust system for corrosion, particularly at mounting points and the rear silencer box where salt ingress is common, and verify the timing belt or cam belt replacement interval if the vehicle is fitted with one, as Audi's recommended intervals typically fall within this mileage range for petrol engines and are critical to engine survival if overlooked. Confirm the service book stamps and recent fluid history, including brake fluid replacement every two years and coolant and transmission fluid changes per manufacturer schedule, and test the 12V battery under load as batteries of this age frequently fail without warning, particularly as the vehicle's electrical systems are heavily computerised. Finally, a scan for any stored fault codes via an OBD tool would be prudent, as Audi-specific systems such as the mechatronic unit, turbo actuator, and emissions sensors can develop intermittent faults that do not yet illuminate a dashboard warning but may indicate developing concerns.
