1999 Mercedes-Benz 412 D Diesel · T207 AVP

Structural corrosion and recurring braking system issues define the mechanical profile of this vehicle, with the most recent test on 29 September 2026 confirming ongoing concerns regarding the offside rear integral body structure and the nearside rear service brake. The vehicle has shown a pattern of escalating advisories related to corrosion and braking components over the last four years, transitioning from isolated brake pipe corrosion in 2022 to more significant structural observations in the rear wheel arch areas and binding brakes in 2026. While the vehicle passed its most recent inspection, the presence of both structural corrosion and brake wear indicates a trend of deteriorating component integrity that requires close monitoring. The recorded mileage of 222,201 miles over approximately 27 years represents a consistent usage pattern of roughly 8,230 miles per year. This level of annual accumulation is typical for a vehicle of this age and suggests a steady rate of mechanical wear rather than extreme high-mileage usage or long periods of stationary neglect. Mechanically, this consistent mileage profile implies that components such as the drivetrain, suspension, and braking systems have been subjected to regular, predictable cycles of use, which aligns with the documented wear on consumables like brake discs and the gradual progression of corrosion noted in the MOT history. Prospective buyers should pay particular attention to the integrity of the chassis and braking hardware. The history of corroded brake pipes across multiple locations in 2022, combined with the recent advisory for a binding nearside rear brake, necessitates a thorough inspection of the entire hydraulic system. During a test drive, listen for any uneven pulling under braking or a sensation of the brake pedal sticking or failing to return fully. The advisory regarding pitted or scored front brake discs suggests that the friction surfaces are reaching the end of their service life; look for any significant vibration or judder through the brake pedal when slowing from higher speeds. The structural advisories regarding the offside rear inner wheel arch and the previous reports of corrosion on the rear cross member and lower valance are critical points of interest. While the current records state that structural rigidity is not significantly reduced, the recurring nature of these observations suggests that oxidation is an active process on this vehicle. On a test drive, pay close attention to the rear suspension area; listen for any knocks, clunks, or metallic creaks when traversing uneven surfaces, which could indicate that the structural corrosion is beginning to affect the mounting points or the stability of the rear subframe and suspension linkages.
