2009 Volvo S40 1.6L Diesel · CA59 FBC

Recurring issues with suspension components, braking systems, and tyre maintenance define the mechanical profile of this Volvo S40. The most recent test on 24 March 2026 resulted in a pass, but it follows a history of several dangerous and major failures, particularly regarding tyre legality and suspension integrity. There is a visible trend of progressive wear in the suspension and braking systems, moving from major ball joint failures in 2023 to current advisories for worn front suspension arm bushes and misting shock absorbers. This pattern suggests that while the vehicle is being brought back to a legal standard, several wear-related components are approaching the end of their functional life. The vehicle has covered 123,021 miles over approximately 17 years, which equates to an average annual usage of roughly 7,237 miles. This represents a relatively low-to-moderate mileage profile for a vehicle of this age. While lower annual mileage can reduce the frequency of drivetrain wear, the MOT history shows that the vehicle has been subject to significant component degradation, specifically regarding tyres and suspension linkages. The usage pattern does not show any significant gaps in testing, but the mechanical records indicate that the components are ageing in line with the vehicle's chronological age rather than being driven into the ground by high mileage. A physical inspection and test drive should focus heavily on the suspension and steering geometry. Given the recent advisories for worn front suspension arm bushes on both sides and the previous history of worn ball joints, you should listen for knocking or clunking noises when driving over uneven surfaces or speed bumps. The advisory regarding the nearside rear shock absorber showing light oil misting, combined with a previous major failure for a serious fluid leak on the same component in 2025, warrants close monitoring. If the shock absorber is failing, you may experience excessive body roll during cornering or a bouncing sensation after hitting bumps. Braking and tyre condition also require scrutiny. The record shows a history of dangerous tyre failures, including exposed cords and incorrect tyre sizes being fitted to the same axle, alongside recent advisories for pitted and scored brake discs. During a test drive, check for any pedal judder or pulsation under braking, which could indicate disc deterioration, and listen for any grinding noises. Furthermore, the nearside rear drive shaft constant velocity boot was flagged as severely deteriorated in the latest test; if this boot splits completely, it will lead to rapid joint failure, often characterised by a clicking sound when turning the steering wheel at low speeds.
