2011 Mercedes-Benz B-Class 2.0L Diesel · 2 JOK

The 2011 Mercedes-Benz B-Class passed its most recent MOT on 19 June 2024 at 80,325 miles, but the maintenance trend is best described as stable with persistent corrosion concerns rather than genuinely resolving. The tester flagged corroded brake pipes front-to-rear, a corroded fuel filler neck, all four brake discs corroded, and cracking on the offside rear tyre. These advisories have appeared repeatedly across multiple tests, indicating the vehicle has been running with known surface corrosion on braking components and fuel system pipework for some time without wholesale remediation. The car did fail the day prior on 18 June 2024 for an excessively worn nearside front suspension arm ball joint and an excessively corroded offside front brake pipe, both of which were evidently rectified before the retest passed 24 hours later, so at least some reactive repairs are being carried out. The mileage trajectory tells a story of very light use. Between the June 2022 pass at 74,493 miles and the June 2023 pass at 77,583 miles, the car covered just 3,090 miles in twelve months. From June 2023 to June 2024 it added only 2,742 miles, arriving at 80,325. Over the full fifteen-year span that equates to roughly 5,355 miles per year, well below the UK average. The record shows no dramatic gaps or sudden accumulation, just consistently low annual distances. Low mileage can preserve certain components, but it also means the vehicle may have spent extended periods stationary, which accelerates rubber deterioration, brake disc surface corrosion, and moisture-related rust in exactly the areas the MOT history repeatedly highlights. A buyer should focus their physical inspection on the underbody and wheel arches, paying close attention to the brake pipe runs along the chassis and the fuel filler neck area where corrosion has been flagged in both 2022 and 2024. Surface corrosion on brake discs is common on lightly used vehicles, but corroded brake pipes concealed under grease or other material represent a more serious concern that warrants a thorough check for wall thickness loss. The nearside front shock absorber was recorded as seriously leaking fluid during the June 2022 failure, so any signs of oil misting on the damper body or uneven suspension behaviour on a test drive should be treated as a red flag. The front road wheel distortion noted in both 2022 and 2023, combined with recurring front tyre wear and perishing, suggests the tracking and wheel condition were never fully corrected. Cracking on the offside rear tyre in 2024 adds to a pattern of neglected tyre condition. Overall, this record reflects a vehicle that has been kept on the road with targeted fixes rather than proactive upkeep. The corrosion themes are consistent and longstanding, and a pre-purchase inspection should prioritise structural integrity of the braking and fuel systems above cosmetic concerns.
