2005 Nissan Micra 1.5L Diesel · NA05 TOH

The defining mechanical theme in this Micra's MOT history is the emergence of structural corrosion at the rear sills during 2024, breaking what had otherwise been a stretch of clean passes. The most recent test on 7 November 2024 recorded a pass, but it came with advisories for corrosion to both the nearside and offside rear outer sill sections, which were classified as not significantly reducing structural rigidity at that point. Historically, the car has been roadworthy without drama: it passed without defect in 2020, 2022, and 2023, and its only failure recorded since 2019 was a straightforward presentation issue in November 2021 (insufficient washer fluid) which was rectified the same day, allowing the car to pass at the same visit. Two earlier 2019 advisories for discoloured indicators and corroded front brake discs were not repeated in subsequent records, suggesting those items were addressed. The shift from a defect-free record to multiple advisories concentrated on the bodywork, headlamp output, and rear wheel bearing in a single test does indicate an emerging pattern of age-related deterioration worth monitoring rather than a fundamentally sound baseline. Recorded mileage stands at 78,543 miles across approximately 21 years, giving an annual accumulation of around 3,740 miles, which is notably low for the age and class of vehicle. Annual MOT testing is reasonably consistent from 2019 onwards, with no multi-year gaps that would suggest the car was laid up or off the road for extended periods, although no tests are recorded between 2019-04-16 and 2020-11-18 or between 2021-11-23 and 2022-11-19 in the supplied data, which could simply reflect a change of test station rather than non-use. Mechanically, this profile typically means reduced wear on major drivetrain components such as the engine, gearbox, and clutch, but it can also accelerate degradation of rubber items, brake calipers, and exposed underbody components due to infrequent use and longer standing periods. The very low cumulative mileage is consistent with the advisory for a slightly noisy offside rear wheel bearing in 2024, as lightly used vehicles often show this symptom as surface rust forms on the bearing surfaces after periods of inactivity rather than through high-mile wear. The rear sill corrosion is the priority item to inspect personally, as MOT categorisation of structural rigidity not significantly reduced can change quickly once perforation begins, and sill condition is a common issue on Micras of this generation, particularly around the jacking points and wheel arch lips. On a physical inspection, press the lower sill area firmly with a gloved hand or tap gently with a screwdriver handle to detect any softness or flaking beyond surface oxidation, and check the inner sills and rear wheel arch seams for bubbling paint or visible perforation. The advisory for the offside rear wheel bearing warrants a road test specifically on a quiet surface: with the windows down and at low speed, listen for a humming or rumbling noise that rises and falls with road speed and that may change when gently cornering left or right to load the bearing; any significant noise, or a noise accompanied by steering wander, suggests the bearing is deteriorating and should be replaced. The headlamp lens product flagged on both front lamps in 2024 should also be examined in person, as it may represent early moisture ingress or oxidisation of the polycarbonate lens, both of which will progressively reduce light output and would be expected to draw future advisories. On test, verify that main beam, dipped beam, and side lights are all functioning and check that the lens surfaces have not become heavily pitted or crazed, as restoration beyond cleaning is generally the only remedy at that stage. Front brake discs showing corrosion in 2019, while not repeated as an advisory since, are worth confirming with a short test drive: light brake application from around 30 mph should produce smooth, progressive deceleration without vibration through the pedal or steering wheel, which would indicate the discs have not developed excessive lip wear or runout. The vehicle's low annual mileage and the recent cluster of age-related advisories point to a car that remains roadworthy but where close attention to sill integrity, rear wheel bearing noise, and lighting performance should form the core of any pre-purchase evaluation.
