2018 Audi A4 2.0L Diesel · LL18 KWD

The most recent MOT on 31 October 2023 was a pass, with the only recorded advisory being that the front tyres are worn close to the legal limit and show edge wear. Prior to that the car failed a test on 4 November 2021 due to rear brake pads being dangerously thin, but it has subsequently passed two further tests without any recorded defects. This pattern indicates that the major safety issue identified in 2021 has been remedied and the vehicle’s overall maintenance trend has moved from a concerning point to a stable, albeit slightly ageing, condition. The recurring tyre wear advisory does suggest that the tyre tread is approaching the end of its serviceable life and should be monitored closely. At 53 624 miles recorded for a 2018 model, the car averages roughly 6 700 miles per year, which is typical for a vehicle of this age. The mileage does not show any periods of unusually high accumulation that would accelerate wear on major components, nor does it suggest prolonged inactivity that could lead to age‑related degradation. However, the relatively modest annual usage does raise the possibility that the car may have spent extended periods standing, a factor that can affect battery health, tyre rubber, and seals if not periodically driven. Prospective buyers should give the tyres immediate attention. Verify the actual tread depth on both front and rear wheels, looking for any uneven wear patterns that could indicate mis‑alignment or worn suspension bushes. Sidewall cracking or hardening is a sign of rubber perishing and would warrant replacement even if the tread appears adequate. The rear brake system should be inspected thoroughly; confirm that the pads now exceed at least 3 mm in thickness and that the discs are free of scoring, glazing or excessive rust. During a test drive listen for any squeal, grinding or shudder when applying the brakes, and feel for a firm, consistent pedal travel. Also check the condition of the front suspension—inspect the rubber bushes, control arm joints and coil springs for any signs of leakage, looseness or excessive play that could manifest as clunking over bumps. Given the vehicle’s age, a broader set of time‑based checks is advisable. Test the 12 V battery voltage under load and assess its ability to hold charge, especially if the car has been stationary for long periods. Examine the under‑carriage for corrosion on the chassis, exhaust hangers and suspension mounting points, and ensure there are no rust‑induced holes that could compromise structural integrity. Verify that the engine oil, coolant and brake fluid have been changed within the manufacturers’ recommended intervals—brake fluid typically requires replacement every two years, and coolant can degrade with age, leading to overheating. Look for any fluid leaks around the engine bay, under the vehicle and at the rear, and ensure all lights, wipers and electronic aids operate correctly. A complete service book with regular stamps will further corroborate that the car has been maintained in line with its mileage and age.
