2006 Honda Civic Sport I-Ctdi 2.2L Heavy oil · UFZ 9328

The Honda Civic Sport I-CTDi’s most recent MOT, conducted on 10 December 2023 at 176,887 miles, passed with no advisories or defects—a clean result that suggests the vehicle was in a sound mechanical state at that time. However, the preceding history reveals a concerning pattern of two consecutive fails in late 2022, both at mileages of 172,847 and 172,912, with no recorded defects logged. This inconsistency—passing in November 2022 before failing twice within a month—implies either intermittent issues that were resolved before the final test or a tester discrepancy. Without documented faults, it’s impossible to pinpoint the cause, but the trend is unstable given the abrupt shift from pass to fail without explanation. The mileage accumulation is steady and typical for a 20-year-old vehicle, averaging around 8,844 miles per year, which aligns with moderate use. The gap between the 2022 fails and the 2023 pass covers roughly 4,000 miles over a year, suggesting the car was either stored or driven sparingly during that period. The absence of mileage spikes or prolonged inactivity raises no red flags, though the lack of detailed MOT records in 2022 leaves some uncertainty about underlying issues that may have been addressed. Given the clean 2023 result but the unexplained fails in 2022, a buyer should prioritise a thorough inspection of the diesel particulate filter (DPF), exhaust emissions, and turbocharger operation, as these are common failure points in CTDi engines that might not always trigger visible MOT defects. The suspension—particularly the rear coil springs and bushes—should be checked for wear, as binding brakes were not recorded but could have been the cause of the fails. Structural corrosion, especially around wheel arches and sills, should also be scrutinised, as rust can compromise safety without immediate MOT consequences. Finally, verify the service history for evidence of any unresolved repairs between the 2022 fails and the 2023 pass.
