2009 Mercedes-Benz A-Class 1.5L Petrol · LS58 ADU

The vehicle most recently passed its MOT test on 1 December 2025, though this followed an earlier failure on 26 November 2025 which was subsequently rectified. Despite the pass, the overall maintenance trend shows clear signs of deterioration rather than stable condition. Across the recorded MOT history there is a recurring and persistent pattern of defects relating to the constant velocity drive shaft boots, which have been flagged as severely deteriorated or split on multiple occasions between 2022 and 2025, indicating an unresolved issue with the gaiters allowing dirt ingress and risking premature joint failure. Steering rack inner joint play has also been advised upon across several tests since at least 2022, and a handbrake high advisory has been carried forward. More seriously, the November 2024 test recorded major defects for both front lower suspension arm ball joint dust covers failing to prevent dirt ingress, and the 2022 test recorded dangerous defects for both rear tyres with exposed ply or cords. These are not isolated observations but represent accumulating wear points consistent with a vehicle that is not being fully addressed between tests. The recorded mileage of 100,166 miles on a 2009 registration equates to an annual average of approximately 5,892 miles, which is substantially below typical usage for a vehicle of this age. This low mileage figure suggests either prolonged periods of standing or genuinely limited use, both of which carry distinct mechanical implications. Extended standing allows corrosion to take hold on exposed steel components such as brake discs, calipers, suspension springs, and underbody structure, while also degrading rubber and polymer items through age rather than wear. The advisories recorded for rear coil spring corrosion in 2023 are entirely consistent with this low-use, age-related deterioration profile, and it is reasonable to expect further corrosion-related advisories to develop on suspension components, exhaust mounting brackets, and underbody seams given the vehicle's age. Given the recurring advisories regarding steering rack inner joint play, a prospective buyer should undertake a careful test drive paying particular attention to steering feel. Any knocking, clunking, or slackness when traversing uneven road surfaces or turning the wheel from lock should be taken seriously, as rack internal joint wear typically progresses and ultimately requires replacement of the steering rack assembly. The repeated CV boot deterioration is another priority inspection point, as perished or split boots allow grease escape and contamination of the joint, leading to vibration under load and eventual drive shaft replacement. During a physical inspection, the boots should be examined for tears, grease deposits on the surrounding suspension components, and any clicking noises during tight low-speed manoeuvres. The rear coil spring corrosion advisories warrant a visual examination of the springs for advanced surface rust and any signs of sagging, which would manifest as a reduced rear ride height or uneven loading. Beyond the recorded defects, the age and low mileage profile demands attention to several time-based deterioration factors. Tyres on a low-mileage vehicle of this age frequently suffer from sidewall perishing and cracking even when tread depth remains adequate, and the recent advisories for rear tyre damage and perishing confirm this is already occurring. Brake discs and calipers are prone to seizing or developing severe corrosion pitting from standing, which can cause brake shudder, pulling, or a spongy pedal on first application. The 12V battery should be load tested, as batteries beyond five years of age frequently fail without warning, particularly on vehicles used for short journeys. Coolant, brake fluid, and automatic transmission fluid if applicable should be checked for service history, as these degrade with calendar age regardless of mileage, with brake fluid being particularly hygroscopic and prone to boiling under heavy use if not refreshed every two years. A compression test or at minimum a thorough cold-start observation would also be prudent given the engine's age, listening for any timing chain rattle from the M266 or similar powerplant commonly fitted to this model, which is known to develop timing chain stretch with high mileage and age. Finally, verifying a complete service history and ensuring all advisories from previous tests have been properly addressed will be essential in determining whether this vehicle represents sound value or simply deferred maintenance.
