2008 Volvo S40 2.0L Diesel · ND08 ARU

Recurring exhaust corrosion and previous drivetrain component failures define the mechanical profile of this Volvo S40. While the most recent test on 10 June 2026 resulted in a pass with no recorded defects, the vehicle has shown a persistent pattern of advisories regarding the middle exhaust outer skin corrosion dating back to at least 2022. This issue was accompanied by a significant failure in June 2023, where both the nearside and offside front inner drive shaft joint constant velocity boots were recorded as split or insecure. Although these CV boots were addressed to secure the pass, the continued presence of exhaust corrosion suggests a long-term trend of oxidation in the exhaust system that has remained a consistent feature of the MOT history over the last four years. The vehicle has covered 171,965 miles over its eighteen-year lifespan, representing an average annual accumulation of approximately 9,554 miles. This usage pattern is consistent with typical UK driving habits for a vehicle of this age and does not indicate periods of prolonged inactivity or excessive high-speed motorway mileage. Mechanically, this level of steady usage suggests that components such as the suspension bushes, braking system, and drivetrain have been subject to regular, predictable wear rather than the accelerated degradation often seen in high-mileage vehicles or the potential seizing issues associated with very low-mileage cars that sit idle for long periods. Prospective buyers should pay close attention to the exhaust system and the front drivetrain during a physical inspection and test drive. Given the multi-year advisory for middle exhaust outer skin corrosion, it is necessary to check if the corrosion has progressed from surface oxidation to structural thinning that could lead to a sudden failure or increased exhaust noise. During the test drive, listen for any changes in exhaust note, such as a deep drone or increased loudness, which could indicate the integrity of the silencer or middle section is compromised. Additionally, while the CV boot failures were resolved, the driver should remain alert for any clicking or popping sounds when turning the steering wheel at low speeds, which would indicate further wear or issues within the drive shaft joints. The 2024 advisory regarding inner edge tyre wear on the front axle warrants a specific check of the steering and suspension geometry. Uneven tyre wear of this nature often points to misaligned front wheels or worn suspension components such as tie rod ends or control arm bushes. On the test drive, the vehicle should be checked for any pulling to one side or a wandering sensation through the steering wheel, particularly when navigating straight sections of road. Ensuring that the steering feels precise and that there are no knocks or knocks felt through the floorpan when driving over uneven surfaces will help confirm whether the underlying causes of the tyre wear have been rectified.
