2011 Mercedes-Benz B-Class 1.5L Petrol · LP11 SYS

Chronic corrosion of the brake pipes is the defining mechanical characteristic of this vehicle, appearing as a recurring advisory across every test since October 2023. While the vehicle passed its most recent inspection on 2 July 2026, the persistence of these corrosion warnings across multiple years suggests a progressive deterioration of the braking system's structural integrity. This trend is compounded by repeated advisories regarding tyre wear and perishing, indicating a pattern of consumables reaching their wear limits without immediate replacement. With 95,208 miles recorded over approximately 15 years, the vehicle has averaged roughly 6,347 miles per year. This usage pattern is typical for its age, meaning the drivetrain and engine have likely experienced a standard rate of wear. However, the consistent appearance of corrosion and tyre degradation despite this moderate mileage suggests that environmental factors may have influenced the condition of the chassis and rubber components more than high-mileage wear alone. Particular attention must be paid to the braking system, specifically the brake pipes which have been flagged for corrosion on both the nearside and offside front and rear sections. During a physical inspection, these lines should be checked for excessive scaling or flaking of the protective coating. Additionally, the history of pitted rear brake discs and slight play in the offside front track rod end warrants a focused test drive. Listen for any knocking or clicking sounds when turning the steering wheel from lock to lock and feel for any unevenness or judder through the brake pedal during deceleration. The tyre condition is a pressing immediate concern, as the July 2026 test highlighted both front tyres as being worn close to the legal limit and the nearside rear tyre as cracking or perishing. A close inspection of the tyre sidewalls is necessary to identify deep weather-checking or cracks. Ensure that the tyre tread is consistent across the width of the tyre to rule out alignment issues, which may be linked to the previously noted play in the track rod end.
