2018 Peugeot 208 1.2L Petrol · YT68 OAJ

The defining mechanical concern in this Peugeot 208's record is the unresolved exhaust failure captured at the May 2026 test, where the vehicle was recorded as failing on a major rear exhaust leak alongside an out-of-specification lambda sensor reading after the second fast idle, before passing the same day with no defects recorded at retest. The fact that the retest was clean suggests remedial work was carried out on the spot or shortly after, but a lambda sensor reading outside limits combined with a major gas leak points to either a deteriorated rear section, a compromised joint, or a sensor that has reached the end of its service life. Buyers should treat this as the most pressing residual risk, because the underlying catalyst and oxygen sensor health is not something the MOT can confirm once the exhaust has been sealed and the sensor replaced. Layered beneath that, there is a clear pattern of recurring advisories on front suspension arm pins or bushes, first noted in 2025 on both sides, suggesting the polyethylene or rubber bushes in the lower wishbones have begun to lose compliance and may now be approaching a movement threshold. Tyre-related advisories in 2024 across both fronts and the offside rear indicate sidewall damage has been an intermittent issue across multiple replacement cycles. Against an eight-year life, the recorded 43,810 miles equates to roughly 5,476 miles annually, which is low for a 2018 supermini and consistent with short urban journeys rather than sustained motorway use. The mileage progression shows consistent annual accumulation with no apparent gaps in testing and no sudden jumps, indicating the vehicle has remained in active service throughout its life rather than being laid up for extended periods, which removes the typical concerns around seized brakes, perished fuel system components, and 12V battery degradation that come with long storage. Low annual mileage of this nature does, however, mean that oil changes are likely to have been on a calendar basis rather than mileage, and short trips are harder on cold-start wear, exhaust condensate corrosion, and tyre age cracking, the latter being directly reflected in the repeated tyre advisories. The relatively gentle rate of accumulation is favourable for the engine, clutch, and gearbox internals but means consumable wear on pads, discs, and clutches will be light to moderate. On a physical inspection, priority should be given to the front suspension, given the bilateral advisory on the arm pins or bushes at the 2025 test. With the vehicle on a ramp or over a pit, look for vertical or rotational play in the lower wishbone bushes by hand, listen for clonking or knocking from the front end over speed humps and uneven road surfaces, and check whether the steering feels vague or wanders under braking, all of which would indicate the bushes have now worn past the advisory threshold into the failure range. Inspect the rear exhaust box, the joint between the centre and rear sections, and the mounting rubber for fresh weld repairs or replacement components, and verify that any lambda sensor fitted is genuine and properly torqued, as aftermarket sensors of poor quality can produce the same out-of-range readings as a failed original unit. On the road, monitor for any ticking or hissing from the rear underside on cold start, any increase in engine noise or roughness under partial throttle, and the illumination of the emissions or engine management warning light, as the prior lambda fault can recur if the replacement sensor or catalyst is marginal. For the tyres specifically, the 2024 advisories for cuts not reaching the ply and the 2026 advisory for cracking and perishing on the offside rear point to age-related rubber degradation rather than kerbing damage, which is a common consequence of low-mileage use where tyres remain fitted for several years and outlast their functional lifespan despite retaining tread depth. Confirm the production date by checking the DOT stamp on the sidewall of all four tyres and reject any that are older than six years, as Peugeot 208 specification tyres in this size tend to be low-profile and age-crack prematurely when left fitted for extended periods. Finally, because the record contains no brake, brake pipe, or corrosion advisories, structural condition is not flagged as a concern, but a thorough underbody check for surface rust on the rear axle, subframe, and exhaust hangers would be prudent given the major exhaust leak recorded, as corroded mounting points are a frequent root cause of such failures on vehicles of this age.
