2012 Mercedes-Benz B-Class 1.8L Diesel · RC04 KSC

The vehicle remains roadworthy, but the maintenance history reveals a persistent trend of deferred repairs regarding structural corrosion. While it passed the most recent test in July 2025 at 88,449 miles, the record shows recurring failures that are only intermittently addressed rather than overhauled. The trend is stable in a negative sense, as the same issues with corroded brake pipes and coil springs appear year after year, indicating a reactive rather than proactive maintenance strategy. At 14 years old, the recorded mileage of 88,449 miles represents an average of approximately 6,300 miles per year, which is consistent with low-to-moderate usage. The data shows consistent annual testing, with roughly 8,400 miles covered between July 2024 and July 2025, and another 5,600 miles leading up to the most recent test. However, the low mileage has not prevented environmental degradation, suggesting that the vehicle has likely been exposed to the elements for long periods, leading to the observed rust onbody components. A buyer must conduct a thorough physical inspection of the rear suspension and braking hydraulic lines. The tester flagged corroded rear brake pipes covered in grease in 2023, 2024, and 2025; the presence of grease often masks the true extent of metal thinning and can lead to sudden pipe failure. Similarly, the corrosion on both rear coil springs has been a noted defect for three consecutive years, which increases the risk of snapped springs under load or cold temperatures. The front end also requires scrutiny following the failures for a fractured offside front road wheel and worn anti-roll bar linkage joints in 2023 and 2024. While these specific items were repaired to secure a pass, the recurring mention of tyres worn to the legal limit in 2023 and 2025 suggests that basic consumable maintenance is often neglected until a failure occurs. Check for uneven tyre wear and ensure the corrosion on the subframe and brake lines has not progressed into structural integrity issues.
