2008 Vauxhall Astra SRI Cdti 1.9L Diesel · SNZ 1668

The Vauxhall Astra CDTI’s most recent MOT, conducted just two months ago on 21 May 2025, confirms it passed without any defects recorded. However, the preceding test on 1 May 2025—just 20 days earlier—resulted in a failure, though no specific faults were logged. This pattern of consecutive tests suggests either a rushed or poorly documented maintenance cycle, as the vehicle was not driven between tests to address any underlying issues. The last full pass before this anomaly occurred in March 2022, meaning the car has operated for nearly three years without a single advisory or defect noted in the official record. While the most recent pass is technically current, the abrupt failure followed by a pass without explanation raises questions about whether critical components were overlooked or repaired between tests. The recorded mileage of 136,028 miles over 18 years equates to an average of approximately 7,557 miles per year, which is typical for a vehicle of this age. The gap between the 2022 and 2025 tests—just under three years—shows a consistent but irregular testing interval, with no evidence of rapid mileage accumulation or prolonged periods of inactivity. The 688-mile increase between the failed and passed tests in May 2025, however, is unusually low for such a short interval, implying the vehicle was likely stationary or driven minimally during that period. There is no clear indication of aggressive driving or neglect, but the lack of advisories or defects in the 2022 tests contrasts sharply with the unexplained failure in 2025, warranting closer scrutiny of components prone to gradual failure. Given the sparse MOT record, a buyer should prioritise an independent inspection of the suspension system, particularly the rear coil springs and bushes, as these are common failure points on this model at this mileage. The repeated tests without defects could mask issues such as binding rear brakes or worn suspension mounts, which often go unnoticed until they cause handling or braking problems. Corrosion at wheel arches, sills, and the subframe should also be examined, as the CDTI’s turbocharged engine and diesel exhaust system are susceptible to rust-related leaks. The absence of advisories in the 2022 tests suggests these areas may have been in better condition then, but three years of use without maintenance could have allowed minor issues to develop. Finally, the turbocharger and intercooler should be inspected for oil leaks or carbon buildup, as these are critical to the engine’s longevity and often go undetected until they fail.
