2006 Citroen Relay 2.0L Diesel · SS06 PCS

Chronic corrosion affecting the rear suspension mounting areas on both the chassis and the nearside inner sill is the primary mechanical concern for this vehicle. This issue has persisted across the last three years of testing, appearing as an advisory in 2024 and remaining present through the most recent pass on 20 April 2026. While the vehicle has passed its latest inspection, the recurring nature of these structural advisories suggests a progressive degradation of the rear mounting points. The recorded mileage of 51,676 miles is exceptionally low for a twenty-year-old commercial vehicle, averaging approximately 2,584 miles per year. Such low annual accumulation often indicates that the vehicle has spent significant periods stationary or has been used for very short, light-duty journeys. Mechanically, this usage profile increases the likelihood of components degrading through age rather than wear, and can often correlate with the type of surface corrosion seen on the chassis and sills due to prolonged exposure to damp environments without the heat and airflow of regular long-distance use. Immediate attention is required for the front tyres, as both the nearside and offside front tyres were flagged as worn close to the legal limit or worn on the edges during the April 2026 test. During a test drive, the buyer should listen for uneven road noise or feel for any steering instability or pull, which may indicate alignment issues contributing to the edge wear. The recorded failures for the windscreen washer system and stop lamps suggest a pattern of minor electrical or fluid-system lapses that should be verified. A detailed physical inspection of the rear chassis and nearside inner sill is essential to determine the current extent of the corrosion. While the DVSA currently classifies this as not excessive, the progression over three years of MOTs warrants a close look for flaking metal or deep pitting around the suspension mounting points. During the test drive, pay close attention to any unusual knocks or instability coming from the rear of the vehicle when traversing uneven surfaces, as this could indicate that the corrosion is affecting the rigidity of the suspension mountings.
