2009 Mercedes-Benz B-Class 2.0L Diesel · LS59 OPG

The latest MOT test for this 2009 Mercedes-Benz B-Class on 2025-09-12 resulted in a passing grade, though it included a single advisory regarding play in the steering rack inner joint(s). Comparing this to the preceding MOT history, the overall maintenance trend appears stable rather than deteriorating, with no repeated failures or critical defects beyond the noted advisories. The vehicle has consistently passed its MOTs since 2024, though the presence of recurring minor issues—particularly around the front anti-roll bar ball joints and rear tyres—suggests some wear progression that should be monitored closely. The steering rack advisory is critical to address promptly, as excessive play in the steering system can indicate underlying wear in the rack seals, ball joints, or rack linkage, which may lead to steering instability or premature failure if ignored. The recorded mileage of 82,778 miles for a vehicle aged 17 years represents a relatively low annual usage rate of approximately 4,869 miles per annum, which is unusually low for its age. Such low mileage often reflects periods of prolonged standing or infrequent use, which can exacerbate issues like corrosion from moisture exposure, fluid degradation without regular servicing, and accelerated wear in components that are not actively engaged. While low mileage can mitigate some wear on consumables like tyres and brakes, it also increases the risk of hidden damage from neglect—such as standing corrosion in the suspension, exhaust, or electrical systems—since these components are not subjected to the dynamic stresses of regular driving. The absence of higher mileage suggests that the vehicle’s wear profile may be skewed toward static deterioration rather than dynamic usage wear. For a prospective buyer, the most pressing immediate checks should focus on the steering system and suspension, given the recurring advisories. During a test drive, listen for unusual clunks or rattles when moving through the suspension at various speeds, as these could indicate worn suspension bushes, loose suspension arms, or binding calipers. The steering rack play advisory warrants inspection of the rack seals and ball joints for leaks or excessive movement; if play is confirmed, the rack should be serviced or replaced promptly to prevent steering failure. Additionally, verify the condition of the front anti-roll bar ball joints, which have shown severe dust cover deterioration. Inspect for play or binding in the joints, and check for any signs of oil leakage or excessive wear around the bushings. The rear tyres, which have consistently shown minor cracking or perishing, should be closely examined for sidewall damage, as this can compromise tyre integrity and safety. If cracks are found, consider replacing them soon, especially if they are deep or located in the tread area. Beyond the immediate advisories, the vehicle’s age and low mileage profile necessitate a thorough inspection of several time-sensitive components. Given its age, check the tyre sidewalls for signs of perishing or cracking, which can lead to sudden blowouts or reduced grip. Inspect the brake discs and pads for corrosion, binding, or uneven wear, as standing corrosion can cause binding calipers or seized brake components. Verify the condition of the 12-volt battery and starter motor, as prolonged inactivity can lead to sulfation or electrical system failure. The exhaust system should be examined for signs of rust or structural integrity, particularly around the catalytic converter and tailpipes, as corrosion can compromise emissions performance and safety. Finally, ensure that all fluids—oil, coolant, brake fluid, and windscreen washer fluid—are topped up and free from contamination, as standing fluids can degrade over time. If the vehicle has a service history, verify that the manufacturer-recommended maintenance intervals have been adhered to, particularly for fluid changes and filter replacements, to mitigate hidden wear and potential failure points.
