2015 Mercedes-Benz B-Class 1.5L Diesel · BJ15 LZW

The most recent MOT, conducted on 11 May 2026 at 67,276 miles, resulted in a pass, but the advisory items reveal a maintenance pattern that is neither clearly improving nor deteriorating. The tester flagged front brake discs that were worn, pitted, or scored, though not seriously weakened, alongside a front service brake fluctuation that was noted as not excessive. Both rear tyres were reported as cracking or perishing on the treads, and the nearside front tyre was worn close to the legal limit on its edges. A chipped windscreen was also recorded, deemed not to affect the driver's view. This combination of recurring brake disc wear and persistent tyre degradation suggests the vehicle has been kept on the road without fully addressing underlying wear trends. The mileage accumulation of roughly 6,116 miles per year over eleven years is broadly typical for a vehicle of this age, though the record reveals a notable gap between April 2024 and May 2025, during which the car covered approximately 8,339 miles in just over a year, a sharper increase than the long-term average. The period from April 2022 to April 2024 shows a more gradual accumulation of around 7,000 miles over two years. The MOT history itself is reasonably consistent, with annual tests recorded each spring, though the 2024 test at 53,223 miles was notably sparse in advisories, suggesting either a period of attentive upkeep or a less thorough inspection that year. The recurring theme across multiple tests is brake disc wear and scoring, appearing in 2022, 2023, and 2026 on both front and rear axles. A buyer should inspect the condition of all brake discs and pads in person, paying particular attention to lipping, pitting, and any signs of uneven wear that could indicate binding calipers or seized slide pins. The rear suspension trailing arm bushes were flagged as worn in the 2025 test, and while no excessive movement was recorded, this is a component that deteriorates progressively and warrants a physical check for play or deterioration. The persistent rear tyre cracking noted in both 2025 and 2026 raises questions about storage conditions, age-related rubber degradation, or alignment issues. Both rear tyres should be closely examined for sidewall damage, and their manufacture dates checked to determine whether they are approaching the recommended six-year replacement threshold. The engine oil leak flagged in 2025, described as not excessive, should also be investigated to confirm whether it has worsened or been rectified.
