2015 Vauxhall Astra 1.6L Diesel · BU65 NRL

The Vauxhall Astra’s most recent MOT tests, conducted just six months ago on January 6, 2026, reveal a concerning pattern of repeated failures despite identical mileage readings. Both tests at 146,375 miles were recorded as failed, yet no specific defects were logged—an anomaly that suggests either an administrative error or a vehicle that narrowly missed critical thresholds. The previous cycle in January 2025 also saw a failure at 137,535 miles, followed by a pass at 137,537 miles, indicating a margin of just two miles between failure and approval. This inconsistency undermines confidence in the vehicle’s true condition, particularly if the tester overlooked serious issues like binding brakes, excessive corrosion, or failing emissions. The lack of advisories or defects in any test further raises suspicion, as modern MOTs typically flag even minor wear in suspension bushes or brake pads if present. The recorded mileage of 146,375 miles over eleven years equates to an average of 13,307 miles annually, a rate significantly higher than the UK average for a vehicle of this age. Between January 2024 and January 2025, the mileage jumped by nearly 12,000 miles in just over a year, suggesting either intensive use or a period of neglect before maintenance. The gap between tests—consistently one year apart—implies the vehicle was likely in regular use, but the abrupt failures at identical mileages in 2026 warrant scrutiny. Without service records, it’s impossible to verify whether critical components like timing belts, differential fluids, or suspension linkages were renewed, which could explain the repeated near-failures. A buyer should prioritise an independent inspection of the suspension system, particularly the rear bushes and coil springs, given the Astra’s history of wear in these areas. The repeated MOT failures without defects suggest the tester may have overlooked binding rear calipers or uneven brake pad wear, so a thorough brake inspection—including disc thickness and rotor runout—is essential. Structural corrosion should be checked at wheel arches, sills, and the subframe, as rust can compromise structural integrity without always being visible. Finally, the engine bay and exhaust system require examination for leaks or excessive soot, as emissions-related failures are often the cause of such close-call MOT results. Given the lack of transparency in the MOT history, a pre-purchase diagnostic scan would be prudent to identify any hidden mechanical issues.
