2017 Mercedes-Benz A-Class 2.1L Diesel · MJ67 FWG

The most recent MOT on 2 November 2023 was passed with no recorded defects, and the earlier test on 22 February 2023 also passed but noted a slight play in the off‑side front wheel bearing. The intervening tests in 2022, 2021 and 2020 were all passed with either no defects or only tyre‑wear advisories. Overall the maintenance trend appears stable; the single bearing advisory has not progressed to a failure, and there have been no recurring major defects, suggesting that any emerging issues have been managed or remain marginal. With a recorded 45 661 miles on a 2017 model, the vehicle averages roughly 5 000 miles per year, which is well below the typical UK average for a car of this age. Such low utilisation often points to periods of limited use or extended storage, rather than high‑stress, high‑mileage operation. While reduced wear on major power‑train components can be advantageous, prolonged standing can promote tyre sidewall perishing, battery sulphation, and corrosion of brake discs and suspension joints, all of which merit close inspection despite the modest mileage. The advisory concerning slight play in the off‑side front wheel bearing should be investigated thoroughly. A competent inspection should verify the condition of the bearing race and seals, and a road test should listen for any low‑frequency hum or feel for a subtle wobble when the vehicle is driven at moderate speed, especially on uneven surfaces. Front tyre wear on the outer edges, noted in the 2021 MOT, may indicate aggressive toe‑out or worn front camber bushings; the buyer should check the tyre tread depth across the width, inspect the front suspension bushes, and ensure the steering alignment is within specification. If the bearing play has increased, replacement of the bearing assembly will be required to avoid premature wheel hub failure. Given the vehicle’s age and low mileage, the buyer should also perform age‑related checks: examine tyre sidewalls for cracking, dry rot or hardening, as rubber can degrade even with few miles; test the 12‑volt battery’s cranking voltage and consider a load test, since long periods of inactivity can reduce capacity. Inspect brake discs for surface corrosion or uneven wear that can cause shudder, and verify that caliper pistons move freely without sticking. Finally, confirm that the engine oil, coolant and brake fluid have been replaced at appropriate intervals – typically every 12‑24 months – as fluids deteriorate with time regardless of distance travelled. A full service history and a visual inspection of hoses, belts and the exhaust system will round out a comprehensive pre‑purchase evaluation.
