2008 Citroen C6 2.7L Diesel · GL57 SBV

The Citroën C6’s most recent MOT test on 2026-01-06 at 105,711 miles passed without defects, confirming it remains roadworthy under current UK standards. However, the December 2024 test at 101,488 miles—just 273 miles shy of the previous pass—was the sole failure in this five-year history, though no specific faults were recorded. This suggests either an administrative oversight or a minor, non-recurring issue resolved swiftly. The overall trend is stable, with no repeated advisories or defects, but the 2024 failure warrants scrutiny of components prone to sudden failure at this mileage, such as suspension bushes or brake caliper binding. The recorded mileage of 105,711 miles over 18 years equates to approximately 5,873 miles annually, which is unusually low for a vehicle of this age. The gap between the 2023 and 2024 tests—spanning 11 months with only 2,366 miles logged—indicates prolonged periods of inactivity. This could imply storage-related risks, such as flat tyres, degraded suspension seals, or corrosion from moisture accumulation. Conversely, the rapid 3,296 miles between the 2024 failure and the January 2025 pass suggests the issue was either cosmetic or easily rectified, but it does not rule out latent problems in less visible areas. Given the lack of recorded defects, a buyer should prioritise an independent inspection of suspension components—particularly the rear bushes and coil springs—due to their susceptibility to wear at this mileage. The binding brake caliper advisory from the 2024 failure, if confirmed, would necessitate immediate attention to prevent uneven disc wear or wheel lockup. Structural integrity should also be assessed, especially around wheel arches and sills, where prolonged storage may have accelerated corrosion. Tyre condition, despite no MOT failures, should be verified, as the low mileage might mask uneven wear from static loading. Finally, the exhaust system should be checked for leaks or rust, as catalytic converter failures are common in this model at high mileage.
