2010 Mercedes-Benz B-Class 1.5L Petrol · MA60 PCF

The defining mechanical story of this 2010 Mercedes-Benz B-Class is one of administrative repetition rather than mechanical substance. The DVSA record shows a curious sequence of test results: a pass on 9 June 2025 immediately following a failure on 4 June 2025, and a pass on 17 June 2024 immediately following a failure on the same date. While the initial reaction might be concern, the absence of any recorded defects on either the failed or subsequent passed tests strongly suggests these were administrative refusals or retests, possibly related to emissions readiness flags common on older Mercedes diesels and petrols, or documentation issues, rather than genuine mechanical or structural defects. The intervening years show a clean pass in June 2023, and a completely defect-free record across all five entries. This pattern points to a vehicle that has consistently met roadworthiness standards, with the unusual double-entry events being procedural rather than indicative of a chronic underlying problem. For a sixteen-year-old vehicle, a defect-free MOT history is a strong positive signal, particularly for the structural and corrosion-related checks that become more demanding with age. With 86,119 miles recorded against a sixteen-year life, this B-Class has covered roughly 5,380 miles annually, which is notably low for a car of this vintage. Such restrained annual accumulation typically suggests either sporadic use, perhaps as a second household car, or extended periods of inactivity. The mileage progression between tests is not disclosed in the records provided, but the very low average implies the vehicle has likely spent considerable time stationary. Mechanically, this usage profile carries specific implications. Low-mileage Mercedes vehicles of this era are particularly susceptible to dry-rotten suspension bushes, perished rubber boots on steering and drivetrain components, and aged brake hydraulic seals that can stick or leak after years of light use. The B-Class front strut top mounts and lower control arm bushes are known to deteriorate with age regardless of mileage, and prolonged standing accelerates this. The buyer should therefore not assume low mileage equates to preserved mechanical condition, and should pay particular attention to age-related rubber and polymer components that may have hardened or cracked without ever being exercised. On a physical inspection, focus closely on the suspension system. Listen for clonking or knocking noises over speed humps and uneven surfaces, which would indicate worn anti-roll bar drop links, top mounts, or control arm bushes. The B-Class is also known for rear axle issues, so any knocking from the rear under load or over bumps warrants scrutiny. The steering should be checked for vagueness or knocking when turned on full lock, which can reveal worn tie rod ends or strut top bearings. Pay close attention to the feel of the brake pedal: a soft or spongy pedal, or any pulsation under firm application, may indicate aged brake fluid that has absorbed moisture over time, or corroded brake calipers and discs. Given the low mileage, brake discs are prone to surface corrosion even where pad material remains adequate, so a thorough check of disc condition, rather than just pad thickness, is advisable. Under the bonnet, inspect for any signs of oil leaks from the engine, particularly from valve cover gaskets and the oil filter housing, which are common failure points on Mercedes engines of this era. Check the condition of all coolant and vacuum hoses for perishing, and examine the auxiliary drive belt and tensioner for cracking or noise on startup. A cold start is invaluable: listen for any timing chain rattle from the engine, which on a 2010 model with this mileage profile could indicate stretched chain guides rather than a worn chain itself, a known issue on certain Mercedes petrol units. Verify that the diesel particulate filter, if fitted, has not been subjected to excessive short journeys, as low annual mileage often correlates with regeneration problems. Finally, confirm that all warning systems illuminate correctly on ignition, that the air conditioning produces cold air, and that the automatic or manual transmission selects cleanly, as a vehicle of this age with such light use may harbour issues stemming from infrequent servicing of less obvious systems such as the power steering fluid and transmission oil, both of which require periodic replacement regardless of mileage.
