2007 Honda Jazz 1.3L Petrol · RA07 YBU

The defining mechanical story behind this 2007 Honda Jazz centres on a single, significant exhaust and emissions failure during mid-2024, which appears to have been comprehensively resolved ahead of its June 2025 retest. The vehicle failed on 18 June 2024 with five major defects clustered around the exhaust system, including a major leak of exhaust gases, elevated carbon monoxide at both idle and post-fast-idle, out-of-range hydrocarbon content, and a Lambda reading outside manufacturer specifications at the second fast idle. Such a concentrated emissions failure typically points to either a compromised exhaust joint allowing fresh air ingress that skews the Lambda probe reading, or a catalytic converter that had lost efficiency, potentially compounded by a pre-existing lambda sensor issue. The fact that the car passed cleanly on 20 June 2025 with no advisories, and again on 27 June 2026 with only minor lens and number plate advisories, strongly suggests the exhaust assembly was replaced or repaired in the interim. It would, however, be prudent to verify with documentation what work was undertaken, as replacement exhaust components on a nineteen-year-old vehicle warrant scrutiny for quality of fitment and the age of any associated sensors. Recorded mileage of 133,366 miles on a 2007 registration equates to approximately 7,019 miles per annum, which is broadly typical for a small family hatchback of this age and suggests consistent rather than occasional use. The MOT record shows annual testing from 2023 through 2026 without any significant gaps, indicating the vehicle has remained in regular road use throughout this period and has not been laid up for extended periods. There is no evidence of unusually rapid mileage increases between tests, which would otherwise raise concerns about motorway-derived wear on timing chains, clutch components, or transmission mounts. For a Honda Jazz of this generation, the i-VTEC petrol unit is generally robust, but the cumulative mileage does mean that age-related items such as the valve clearances, ignition coils, and the automatic CVT fluid (if fitted) should be regarded as service items rather than sealed-for-life components. At nearly 134,000 miles, a replacement timing chain, water pump, and thermostat housing would be sensible preventative considerations regardless of any MOT history. Given the specific components flagged in the advisories, a prospective buyer should focus their inspection on the front lighting and number plate condition noted at the most recent test, and most importantly verify the integrity and security of the entire exhaust system from manifold to tailpipe, listening for any ticking under load that would indicate a leaking gasket or failed flexi-joint. During a test drive, pay particular attention to any hesitation, misfire, or illuminated engine management light, as a failed Lambda sensor or degraded catalytic converter could have been replaced with a pattern part that may not match OEM longevity. The 2023 advisory regarding corroded exhaust system suggests the system was already showing surface oxidation prior to the failure, so physical inspection underneath for flaking pipes, perished rubber hangers, and any signs of recent welding or clamping is essential. Listen for clonking from the exhaust on overrun and check for soot deposits around joints which would indicate a current leak. Beyond the exhaust concerns, the clean advisories across suspension, braking, and steering items across all recorded tests is reassuring and suggests the MacPherson strut front and torsion beam rear suspension are holding up well for the mileage. Nevertheless, on a test drive, feel for any knocking from the front suspension over speed humps and uneven surfaces, which could indicate worn anti-roll bar bushes or drop links that have not yet reached advisory threshold. Check the steering for any pulling to one side under braking, which on a Jazz of this age could suggest worn front brake caliper slider pins rather than simply pad wear. Inspect the rear brake drums for binding by confirming the handbrake releases cleanly without dragging, and verify that the tyres are matching in age and tread depth as the MOT does not record this detail. Finally, examine the rear wheel arches and sill seams for any bubbling paintwork, as corrosion in these areas is the most common structural failure point for first-generation Jazz models approaching twenty years of age, even where it has not yet been recorded as an MOT advisory.
