2022 Renault Trucks Master 35 LWB 2.3L Diesel · PF22 EEX

The latest MOT test for the Renault Trucks Master 35 LWB recorded on 2026-07-01 was a pass, though it included two advisories that warrant careful attention. While this outcome represents a return to compliance after a failure in June 2026, the prior test history reveals a pattern of recurring issues, particularly with lighting and electrical systems. The failure in June 2026—where multiple major defects were noted, including snapped indicator and headlamp starlights, non-functional rear lamps, and incorrect beam projection—suggests a potential underlying electrical or wiring problem that may have been exacerbated by the high mileage or environmental exposure. The fact that the vehicle passed in June 2025, with no defects recorded, indicates that the electrical faults may have either been addressed or were less pronounced at that time, but the recent advisories on the rear wheel distortion and Adblue system suggest ongoing or emerging concerns that could escalate without proactive maintenance. The recorded mileage of 132,631 miles for a vehicle aged four years is exceptionally high, averaging approximately 33,158 miles annually—a rate that far exceeds typical usage for a commercial vehicle of this class. Such rapid mileage accumulation places significant stress on critical components, particularly the suspension, braking system, drivetrain, and exhaust components, which are prone to accelerated wear. The high mileage alone justifies a thorough inspection of consumables like brake pads, brake discs, and suspension bushes, as well as fluid levels and condition—oil, coolant, and brake fluid should be checked for contamination or degradation. The rear wheel distortion advisory, if not already rectified, may indicate excessive lateral loads or misalignment, which could lead to uneven tyre wear, steering anomalies, or even structural fatigue in the wheel assembly over time. Additionally, the Adblue system’s failure to function properly could signal issues with the urea injection or sensor, which may require replacement or recalibration to prevent further emissions-related problems or potential engine performance issues. Given the vehicle’s high mileage and the recurring MOT issues, the prospective buyer should prioritise a comprehensive mechanical inspection before purchase. Start with the suspension and steering components: listen for unusual clunks or rattles during cornering or braking, which could indicate failing suspension bushes, broken coil springs, or binding control arms. Inspect the rear wheel assembly for any signs of distortion, excessive play, or corrosion around the hub and bearing, as the advisory suggests this may be a persistent issue. The braking system should be thoroughly examined—check for uneven wear on brake discs, binding calipers, or a spongy or pulsating pedal, which could indicate warped discs or worn brake pads. The electrical system, particularly the lighting and indicator wiring, should be tested under various driving conditions to confirm that all lamps function correctly and that there are no short circuits or frayed connections contributing to the past failures. For fluid and component checks, the buyer should verify the condition of the Adblue tank and wiring, ensuring no leaks or physical damage that could compromise its function. The engine oil and coolant should be checked for contamination or sludge, as high-mileage vehicles are more susceptible to internal wear and fluid breakdown. The exhaust system should be inspected for leaks or excessive backpressure, which could indicate catalytic converter failure or flex pipe damage, given the vehicle’s age and usage. Finally, since the vehicle has been driven extensively, the tyres should be scrutinised for sidewall cracking or perishing, which can occur from prolonged exposure to UV light and heat, even if the tread depth is adequate. If the vehicle has been stored for prolonged periods, check for standing corrosion on the undercarriage, particularly around the wheel arches, exhaust, and fuel system, as moisture and salt can accelerate rust progression. A thorough test drive should include acceleration, braking, and cornering to listen for any unusual noises or vibrations, and the buyer should also verify that all lights, indicators, and mirrors function as expected to ensure compliance with current legal requirements.
