2005 Mercedes-Benz A-Class 1.7L Petrol · CP55 HHV

Corrosion and suspension wear represent the primary mechanical concerns for this vehicle, with a recurring pattern of advisories regarding the rear coil springs and front suspension components. The most recent MOT test on 17 March 2026 resulted in a pass, but it followed a failure on 4 March 2026, and the record shows that issues with the nearside front suspension arm bush and the rear coil spring corrosion have been persistent over several testing cycles. The presence of multiple advisories for corroded coil springs and mounting points, alongside a minor exhaust gas leak, suggests that these components are in a state of progressive deterioration. The vehicle has covered 95,600 miles over its 21-year lifespan, which equates to an average annual usage of approximately 4,552 miles. This is a relatively low rate of mileage for a vehicle of this age. While lower mileage can imply less frequent wear on drivetrain components, it can also coincide with longer periods of inactivity, which may contribute to the observed corrosion on the brake pipes and suspension elements recorded in earlier tests. The low annual accumulation means that mechanical wear is more likely to be driven by age-related degradation and environmental exposure rather than high-frequency component fatigue. A prospective buyer should pay close attention to the suspension and exhaust systems during a physical inspection and test drive. The repeated advisories for the nearside front suspension arm pin or bush being worn suggest that the vehicle may exhibit knocking or clunking noises when traversing uneven surfaces or bumps. Furthermore, the ongoing advisories for corrosion on both nearside and offside rear coil springs, as well as the rear coil spring mounting, necessitate a thorough visual check for structural integrity. You should listen for any metallic creaking or spring-related noises when the vehicle's weight shifts or when navigating speed bumps. The history also highlights previous issues with the braking system and exhaust. While the 2024 failure regarding brake lever movement and the advisory for pitted or scored front brake discs have been addressed or passed since, the older advisory regarding corroded rear brake pipes should be noted. On a test drive, check for any pedal judder or uneven braking performance, which could relate to the previously noted disc condition. Additionally, the minor exhaust leak flagged in the March 2026 test should be monitored for any changes in engine note or noticeable fumes entering the cabin, which could indicate the leak is expanding.
