2011 Mercedes-Benz B-Class 1.5L Petrol · LS11 AXD

This Mercedes-Benz B-Class has demonstrated a stable roadworthiness trend over the past three MOT cycles, with the most recent test on 2025-07-30 confirming a clean pass at 149,980 miles. The absence of defects in both the 2025 and 2024 tests suggests the vehicle has not encountered any recurring mechanical failures that would necessitate urgent attention. However, the consecutive failures in July 2025—just five days apart—are unusual and warrant scrutiny, particularly since no specific faults were recorded. This pattern implies either an administrative oversight or a test centre anomaly, though it does not inherently indicate mechanical issues. The vehicle’s most recent MOT remains valid for just one month, meaning it will require retesting by 2026-08-29, which is due shortly after today’s date. The mileage progression of approximately 12,500 miles annually—from 128,475 miles in August 2023 to 149,980 miles in July 2025—falls within the expected range for a vehicle of this age. There are no significant gaps or abrupt spikes in usage, though the lack of MOT records between 2023 and 2024 is notable. The vehicle appears to have been driven consistently without prolonged periods of inactivity, which could suggest either regular use or a pattern of deferred maintenance. The absence of advisory notes in any of the tests further reinforces that no critical wear items—such as suspension bushes or brake calipers—were flagged as borderline during previous inspections. Given the clean MOT history, a prospective buyer should prioritise an in-person inspection of high-wear components that are not always captured in standard MOT tests. The suspension system, particularly the coil springs and rear bushes, should be examined for uneven wear or corrosion, as these are common failure points in vehicles of this age and mileage. Brake discs and calipers—especially the rear, which were not explicitly cleared in the 2025 failures—must be checked for thickness, binding, or uneven wear patterns. Structural integrity, including underbody corrosion around the sills and wheel arches, should also be assessed, as this is often overlooked in MOT tests but critical for long-term reliability. The engine bay should be inspected for fluid leaks, particularly around the power steering and cooling systems, while the exhaust should be checked for rust or excessive sagging, which could indicate frame or suspension deterioration. The lack of advisories in past tests does not guarantee these areas are pristine, so visual and functional verification is essential.
