2017 SEAT Ibiza 1.2L Petrol · G11 CXT

The most recent MOT test on 28 August 2026 resulted in a pass with no defects or advisories recorded, which is the most reassuring possible outcome from a DVSA perspective. However, this clean result must be viewed in the context of the two immediately preceding tests on 10 and 11 August 2026, both of which failed. The dominant recurring theme across these failures is exhaust emissions, with carbon monoxide content exceeding limits at both idle and fast idle on multiple occasions, alongside a Lambda reading out of specification. A headlamp aim failure and an excessively tinted upper windscreen were also recorded. Looking back further, exhaust emissions were again flagged as a manufacturer-specified limit exceedance in August 2025, alongside wiper and washer deficiencies and a headlamp aim issue. The pattern suggests the vehicle has experienced intermittent compliance problems with emissions and lighting rather than a single isolated incident, and although the latest pass demonstrates it is presently roadworthy, a prospective buyer should approach with awareness that emissions issues on a petrol Ibiza of this age often relate to lambda sensors, oxygen sensor degradation, catalytic converter efficiency, or underlying engine management faults that can re-emerge. The fact that the car passed so soon after these failures indicates remedial work was carried out, but verification of what was actually replaced or adjusted would be prudent. With recorded mileage of 55,742 miles over approximately nine years, this SEAT Ibiza has covered an annual average of around 6,200 miles, which is broadly typical for its age and consistent with regular but modest use. The MOT history shows annual testing since 2023 with no significant gaps or sudden mileage jumps, suggesting the vehicle has been in continuous use rather than left standing for prolonged periods. This pattern is mechanically favourable as it reduces the likelihood of severe corrosion from disuse, seized brake calipers from inactivity, or premature degradation of rubber components and fluids through calendar ageing alone. Nevertheless, the Ibiza is now nine years old and approaching a mileage and age threshold where certain consumables and wear items commonly require attention, regardless of how economically it has been used. Given the recurring emissions failures across multiple tests, a prospective buyer should make engine warm-up behaviour and exhaust output a priority during any test drive. Listen for any irregular idling, hesitation, misfire, or rough running once the engine is warm, and observe whether the engine management warning light extinguishes promptly and remains off. Ask for documentary evidence of what remedial work addressed the August 2026 emissions failures, particularly whether the lambda sensor, oxygen sensor, spark plugs, or catalytic converter were replaced or cleaned. A healthy exhaust system on a petrol Ibiza should produce minimal visible smoke under acceleration, with none at idle or on overrun. If the seller cannot demonstrate clear emissions-related repair invoices, an independent diagnostic scan for stored fault codes and a pre-purchase emissions check at a garage would be highly advisable. It is also worth inspecting the condition and age of the coolant, brake fluid, and engine oil, as these degrade over time and the service history should confirm periodic renewal regardless of the modest annual mileage. Beyond the emissions concerns, the history of wiper, washer, and headlamp aim issues points to general electrical and lighting maintenance that should not be overlooked. On inspection, verify that both front wiper blades clear the screen effectively without smearing, that the washer system delivers a strong jet to both front and rear, and that the headlamp alignment is correct rather than just within MOT tolerance, as misaligned lights compromise night-time visibility. Check the upper windscreen tint band carefully, as the recorded advisory means it sits at the very edge of legality and any subsequent modification or further deterioration could result in a future failure. The nearside registration plate lamp has also been flagged on consecutive tests, so confirm all plate illumination lamps function correctly. Finally, given the vehicle's age, conduct a thorough physical examination of the tyres for sidewall cracking or perishing even if tread depth is adequate, inspect the rear brake drums or discs for corrosion from standing, test the 12V battery under load as batteries of this age commonly fail without warning, examine the suspension for any clonks or knocking over speed bumps indicating worn bushes or coil springs, and check the underside and wheel arches for any corrosion typical of a nine-year-old vehicle. Confirm a complete service book record with stamps at appropriate intervals to verify that time-based items such as cambelt replacement, if due on this engine, and routine fluid changes have been attended to.
