2004 Nissan Micra 1.2L Petrol · WP04 ABU

The most recent MOT on 7 July 2026 resulted in a failure, with major faults recorded for the central stop lamp, exhaust lambda and hydrocarbon readings, and a likely exhaust leak. Over the past three years the pattern has moved from a clean pass in 2024, through a mixed pass/fail in 2025 that highlighted front brake pad wear, a ball‑joint fault and tyre wear, to the present failure, indicating a clear deterioration rather than an improvement in the vehicle’s condition. At 112 513 miles the car averages just over 5 000 miles per year, which is well below the typical usage for a 22‑year‑old hatchback. The low annual mileage suggests the vehicle has spent considerable periods idle, a situation that can accelerate rubber, seal and corrosion ageing even though mechanical wear from distance is modest. The modest mileage does not eliminate the need to scrutinise components that deteriorate with time rather than use, such as bushings, hoses and the battery. The emissions failures point to a probable exhaust leak and a malfunctioning oxygen sensor or catalytic converter, which will cause the lambda and hydrocarbon readings to be out of spec. A visual inspection of the exhaust system for cracks, rust‑through or loose joints is essential, and a test‑drive should be listened to for hissing or ticking noises, especially under acceleration. The central stop lamp must be replaced, and the driver should verify that all other exterior lamps function correctly. Front brake pads were recorded at less than 1.5 mm in 2025, so they will need immediate replacement and the discs should be measured for thickness and surface condition; any pulsation or shudder under braking would confirm disc wear. The near‑side front track‑rod ball joint was noted with excessive play, so the steering should be checked for looseness, clunking when turning, and uneven tyre wear, and the ball joint will likely require replacement. Front lower suspension arm bushes were already flagged as worn, and the near‑side rear coil spring showed corrosion, indicating that the suspension may be approaching the end of its service life and should be examined for cracked or sagging springs, worn bushings and any abnormal noises. Given the vehicle’s age and low mileage, a thorough visual and tactile inspection is advisable. Examine all tyre sidewalls for cracking, dry rot or hardening, as age can render tyres unsafe even if tread depth appears adequate. Check the 12 V battery for sulphation and verify its cranking voltage; a battery older than four years often needs replacement. Inspect all fluid reservoirs for colour change, sediment or leaks, and consider a full service of engine oil, coolant, brake fluid and power‑steering fluid if the service history is incomplete. Finally, ensure the rear registration plate is legible and securely mounted, and confirm that the service book shows regular oil changes and any previous suspension or brake work, as these records will help gauge how well the car has been maintained despite its limited mileage.
