2017 Mercedes-Benz B-Class 1.5L Diesel · FD17 TPV

The latest MOT test conducted in April 2026 resulted in a pass, although it introduced several advisories concerning the braking system and tyre condition. While the vehicle has a history of clean passes, the recent emergence of thinning brake pads and worn discs suggests that the maintenance trend is shifting from a stable state to one where primary consumables are reaching the end of their service life. The presence of these advisories indicates that the vehicle will require immediate financial investment in its stopping gear to maintain optimal safety and performance. The recorded mileage of 27,929 miles is exceptionally low for a vehicle of this age, averaging approximately 3,103 miles per year. While this suggests minimal wear on the engine internals and drivetrain, such low usage often indicates a vehicle that has spent extended periods stationary. This usage profile is frequently more detrimental to rubber components and fluid integrity than consistent high-mileage use, as it increases the likelihood of perishing, seizure, and chemical degradation of essential lubricants. Prospective buyers should pay close attention to the braking system during a test drive, listening for any grinding noises or feeling for pulsations through the brake pedal, which would confirm the wear noted in the latest MOT. The recurring history of tyre perishing and cracking between 2022 and 2023, combined with the recent cut to the nearside front tyre, is a clear indicator of age-related degradation rather than tread wear. A thorough physical inspection of all tyre sidewalls is necessary to check for ozone cracking or bulges that could lead to structural failure, regardless of the remaining tread depth. Due to the low annual mileage, it is critical to verify that the vehicle has been serviced according to time intervals rather than mileage limits, as engine oil degrades regardless of use. The buyer should check for binding brake calipers and inspect the suspension bushes for hardening or cracking, both of which are common in vehicles that stand for long periods. Additionally, the health of the 12V battery should be verified, and the service book should be scrutinized for evidence of calendar-based fluid changes to ensure the long-term reliability of the engine and cooling system.
