2013 Mercedes-Benz B-Class 1.8L Diesel · KM13 FGK

The B‑Class cleared its most recent MOT on 15 January 2026 at 109 767 miles, achieving a pass despite two front tyres worn to 3.5 mm and 3.4 mm and visible corrosion on all brake discs. The vehicle’s maintenance trend shows improvement after a failure recorded on 27 January 2025, when rear brake binding, a rear inner tyre with exposed cords, under‑inflation and a windscreen obstruction caused the test to fail. The same day the car was retested and passed, indicating repairs were carried out promptly. The recent pass therefore reflects a stabilising condition, yet the emerging tyre wear and disc corrosion suggest the wear rate is now accelerating. Mileage accumulation has been fairly steady at roughly 8 500 miles per year, which aligns with the average usage for a 13‑year‑old vehicle. The jump from 97 862 miles in January 2025 to 109 767 miles in January 2026 represents an increase of 11 905 miles over an 11‑month period, exceeding the typical annual gain. This recent surge points to heavier recent use or possibly longer unrecorded intervals between tests. The data set is otherwise complete, with annual entries from 2017 through 2026. A buyer should prioritise a hands‑on inspection of the braking system. Check rear brake pad thickness against the 1.5 mm minimum, examine front pads for wear, and look for disc corrosion or uneven surfaces. Tyre condition is equally critical; verify tread depth on all four tyres, inspect the rear inner tyre for cord exposure, confirm proper inflation, and search for cuts, cracks or uneven wear. The history notes a cracked off‑side front wheel and a windscreen obstruction, so the wheel rim and glass should be examined for structural damage and clarity. Finally, test the headlamp cleaning function and the registration plate lamp, as these have failed previously. Overall, the car remains roadworthy but the combination of near‑limit tyre wear, brake disc corrosion and the recent mileage spike indicate that consumables are approaching replacement intervals. A thorough pre‑purchase inspection will reveal whether the wear is uniform or if there are underlying mechanical issues that could affect safety and future reliability.
