2018 Dacia Logan 1.0L Petrol · YM67 BYX

The most recent MOT on 13 March 2026 shows the Logan passed at 92 841 mi, but it was preceded just three days earlier by a failure for serious exhaust‑emission limits (excess carbon‑monoxide, hydrocarbons and out‑of‑range lambda reading). That failure was not recorded on the pass, suggesting the problem was either remedied or the test was repeated after a short repair. Looking back at the 26 February 2026 failure, a cluster of unrelated defects appears: a minor oil leak, a nail in the nearside rear tyre, a small exhaust leak at the front flexi joint, a malfunctioning engine MIL, two nearside headlamp faults, and a fractured off‑side front anti‑roll‑bar linkage. None of these items re‑occurred in the later pass, but their presence indicates that the vehicle was experiencing several separate wear or maintenance issues within a short period. The pattern therefore is one of intermittent, but fairly serious, problems rather than a steady improvement. The emissions failure is a safety and environmental concern, while the anti‑roll‑bar fracture points to possible chassis stress. The fact that the car passed the next MOT suggests the owner may have addressed the most critical faults, yet the recurrence of different defects within weeks hints at a vehicle that is not yet in a stable condition. Mileage of 92 841 mi for an eight‑year‑old car works out to about 11 600 mi per year, which is close to average use. This figure alone does not indicate excessive wear, but combined with the recent defects it suggests that consumables (brakes, suspension components, exhaust system) may be approaching the end of their service life and could need replacement soon. For a prospective buyer the priority checks should be: A thorough visual inspection of the exhaust system for leaks, corrosion or cracked joints, and a confirmatory emissions test if possible.
