2001 Renault Master 2.2L Diesel · Y993 BSG

The most recent MOT recorded in July 2022 resulted in a failure due to critical structural corrosion. The overall maintenance trend is concerning and shows a clear decline in structural integrity over time. While earlier tests noted general rust and the application of wax oil to mitigate decay, the latest records confirm that the offside rear sub-frame and the central rear vehicle structure near the towbar mounting have become seriously weakened. This progression indicates that the vehicle is suffering from advanced systemic corrosion that has transitioned from superficial surface rust to significant structural failure. With a recorded mileage of 170,212 miles over a twenty-five year lifespan, the vehicle has averaged approximately 6,808 miles per year. This usage rate is typical for a light commercial vehicle of this vintage, suggesting consistent but moderate use rather than extreme heavy-duty haulage or prolonged periods of standing. However, at this mileage, the drivetrain and suspension components are well into their wear cycle. The buyer should expect typical high-mileage degradation of bushings, engine mounts, and transmission internals, which is compounded by the age of the vehicle. The primary concern for any prospective buyer is the structural integrity of the chassis and sub-frames. Given the history of major failures regarding the rear sub-frame and towbar area, a thorough physical inspection of the underside is mandatory. Look for excessive scaling, flaking metal, and areas where the metal has perforated. Be wary of fresh underseal or thick wax oil coatings, as these may be used to conceal severe corrosion. During a test drive, listen for unusual clunks or groans from the rear suspension and chassis, which can indicate movement in weakened structural members or failing suspension bushes. Beyond the chassis, the history reveals recurring issues with constant velocity boots, oil leaks, and ABS faults. Inspect the front drive shafts for any new splits in the rubber boots and listen for clicking sounds during tight, low-speed turns, which would signal a failing constant velocity joint. Check the engine bay and underside for active oil leaks, particularly around the gaskets and seals. The previous ABS warning lamp failures suggest a potential fault in the sensors or the ABS module; ensure the dashboard is clear of warning lights upon ignition and that the brake pedal feel is consistent. Finally, check the rear brake discs for pitting or scoring, as noted in previous advisories, which can lead to reduced braking efficiency.
