2018 Audi A4 2.0L Diesel · YH18 UPD

The vehicle’s MOT record is dominated by recurring front‑upper suspension arm wear and a one‑off major failure of the rear lower coil‑spring mountings in 2023; those two rear mountings were recorded as corroded and seriously weakened, prompting a failure, while the front‑arm bush wear has appeared as an advisory in three consecutive tests. The most recent inspection in June 2026 passed without defects, indicating that the identified issues have either been remedied or are currently within acceptable limits, but the pattern signals that the suspension system remains the primary mechanical concern. At 58,520 mi spread over eight years the average annual mileage sits around 7,300 mi, which aligns with typical usage for a vehicle of this age and does not suggest any periods of prolonged inactivity. The MOT history shows no large gaps between tests, so the mileage progression appears steady rather than indicative of sudden high‑stress usage that could accelerate wear on the suspension, brakes or drivetrain components. When inspecting the car, give particular attention to the front‑upper arm bushings and pins on both sides; feel for any excessive play when the steering wheel is rocked at a standstill and listen for clunking or knocking noises when driving over bumps or potholes. Examine the rear suspension for uneven ride height, excessive bounce, or a soft feeling under load, which could indicate lingering weakness in the lower coil‑spring mountings despite the pass. Check the subframe and surrounding metal for any signs of rust or corrosion that might have contributed to the 2023 failure, and verify that any replacement parts have been fitted with the correct torque specifications. A thorough test‑drive should also include a short high‑speed run to confirm that the car tracks straight without pulling to one side and that the steering returns to centre promptly after a quick swerve. While the MOT passes since 2024 suggest the major defects have been addressed, the recurrence of front‑arm advisories means that a pre‑purchase inspection by a qualified technician, focusing on bush wear, mounting integrity and any residual corrosion, is advisable before committing to purchase.
