2006 Nissan Micra 1.2L Petrol · SM06 FEX

The defining mechanical story of this 2006 Nissan Micra is one of progressive front suspension and underbody deterioration, evidenced by a clear worsening trend across the four recorded MOT tests from 2017 to 2023. The earliest tests in 2017 and 2018 were relatively clean, noting only structural and brake hose corrosion advisories plus a tyre wear item, but by 2019 the pattern shifted to component-level wear with advisories on the front CV boot, anti-roll bar linkage dust cover, and rear coil spring corrosion. By 2022, the test history shows the car had tipped into outright failure territory, with a failed presentation at the start of May 2022 identifying split CV boot ingress and deteriorated anti-roll bar ball joint dust covers, followed two days later by a pass carrying fresh advisories on worn front suspension arm pins or bushes and general underbody corrosion. The most recent entry on 30 November 2023 is a fail, and the nature of the defects is significant: a fractured offside front coil spring, excessively worn offside front lower suspension arm ball joint, track rod end ball joint with excessive play, and failed front position lamps and offside indicator. This combination of items strongly suggests the front suspension and steering assemblies have reached a stage where refurbishment rather than incremental repair is the realistic path. Annual mileage for this 20-year-old Micra averages roughly 6,624 miles, which is broadly typical for its age bracket, but the testing record itself reveals an irregular pattern. There are recorded tests in 2017, 2018, 2019, 2021 (two entries on the same day reflecting a fail immediately retested), and 2022 (two entries two days apart), followed by the 2023 failure. The relatively tight clustering of tests in 2021 and 2022 suggests the vehicle may have been off the road for a period between 2019 and 2021, which can accelerate corrosion on brake components, exhaust fittings, and underbody seams even at modest annual mileage. Combined with the recurring underbody rust advisories across almost every test since 2017, the risk profile leans toward a chassis and underfloor structure that is slowly oxidising rather than failing outright, but which a buyer should expect to continue deteriorating. For a prospective buyer, the priority pre-purchase actions centre on the front suspension and steering geometry flagged at the 2023 test. The fractured coil spring is a known MOT failure item and warrants a physical inspection beneath the wheel arch for any remaining broken coils, with a corresponding listen for sharp clunks or a low-speed thump over speed humps. The worn lower suspension arm ball joint and track rod end play will manifest as a knocking or clonking from the front wheels when turning at low speed, vagueness or wander in the steering, uneven tyre wear particularly on the inner or outer shoulders, and a tendency for the wheel to flop under hard cornering. Both items point toward renewed front suspension arms and a steering rack or at minimum track rod replacement, jobs that on a Micra of this age are often grouped with a wheel alignment. It is also worth asking whether the position lamp and indicator defects from the 2023 failure have been rectified, as electrical earth and connector faults can recur and are quick to verify on a walkaround. The secondary concerns drawn from the MOT history are the underbody and brake line corrosion pattern. General underbody rust has been flagged repeatedly from 2017 onwards, with specific mention in 2017 of slight corrosion on a front cross member and on rear brake hose ferrules. On inspection, a buyer should look for surface scale and any bubbling along the front subframe, engine cradle, and the area around the rear brake pipe unions and flexible hoses, as corroded ferrules on rigid brake lines typically force replacement of sections of pipe rather than the hose alone. The 2019 advisory on the nearside CV boot deteriorated and the 2022 failure item showing the boot split and no longer preventing dirt ingress mean the offside boot should now be checked for fresh grease loss or splits, with any clicking or vibration on full-lock driving indicating worn CV joints. The 2018 oil leak advisory has not reappeared in later tests, but a cold-start inspection underneath for drips and a check of the engine bay for wet oil residue on the cam cover and sump area is sensible. Taken together, the record describes a car whose drivetrain has been reliable but whose chassis, suspension, and underfloor hardware are at the back end of their service life, and any purchase decision should price in a comprehensive front suspension refresh, brake pipe remediation, and continued attention to rust progression.
