2017 Mercedes-Benz A-Class 2.1L Diesel · KT17 KTV

Recurring issues with braking components and tyre wear patterns define the mechanical profile of this Mercedes-Benz A-Class, with the most recent test on 14 October 2025 showing a pass alongside advisories for thinning offside rear brake pads and inner edge wear on the front tyres. The MOT history reveals a consistent trend of brake-related advisories and failures, including a dangerous failure in 2023 regarding brake pad thickness and a major failure in 2024 related to brake performance and wheel bearing testing. This pattern suggests that while the vehicle is being brought up to standard for annual inspections, the consumable components—specifically brake pads, discs, and tyres—are frequently reaching the limits of their service life or being replaced only when they trigger a failure or significant advisory. The vehicle has covered 60,388 miles over approximately nine years, which equates to an average annual usage of roughly 6,710 miles. This mileage is typical for its age and indicates relatively light annual usage. From a mechanical standpoint, this level of mileage suggests that components such as suspension bushes, dampers, and drivetrain elements may not have been subjected to high-frequency heavy load, but the recurring advisories for tyres and brakes indicate that the vehicle's usage pattern may involve significant periods of driving on specific road types or perhaps infrequent replacement of consumables until they reach critical wear levels. Prospective buyers should pay close attention to the braking system during a test drive, specifically looking for any pulsation or judder through the brake pedal, which could indicate the uneven wear or disc pitting noted in the 2024 records. The history of brake performance issues and wheel bearing-related failures necessitates a thorough check for any rhythmic humming or grinding noises from the wheel arches, particularly at varying speeds. Additionally, the repeated advisories for tyres wearing on the inner edges and the 2025 advisory for front tyre edge wear suggest a potential ongoing issue with wheel alignment or suspension geometry. During the inspection, it is advisable to monitor the steering for any pulling to one side or a wandering sensation, which could stem from the previously flagged anti-roll bar linkage ball joint issues or the tyre wear patterns. Given the history of anti-roll bar linkage dust cover failures, listen for any knocking or clunking sounds when navigating uneven surfaces or speed bumps, as this would indicate wear in the suspension linkages. The recurring nature of the brake pad and disc advisories means a physical inspection of the remaining pad thickness and the surface condition of the discs is essential to determine how much remaining service life is available before the next required intervention.
