2009 Smart Fortwo Passion CDI Auto 0.8L Diesel · LD09 UTJ

A remarkably sparse DVSA test history for this 2009 Smart Fortwo Passion CDI presents a mixed picture that warrants careful interpretation. Across five recorded tests spanning 2023 to 2025, the vehicle has alternated between pass and fail outcomes with no specific defects logged, a peculiar pattern that often points to administrative issues such as retests for lighting, tyre condition, or emissions preparation rather than fundamental mechanical deterioration. The most recent test on 5 June 2025 returned a clean pass with no advisories or defects recorded, and the previous pass on 17 May 2024 was equally clean. The two failed tests on 14 March 2024 and 21 March 2023 show no recorded reasons for failure, which is unusual but not uncommon when advisories from a prior test have progressed to failure thresholds without specific component identification at the retest. The overall trend suggests a vehicle that is fundamentally sound but has experienced intermittent compliance issues that did not translate into persistent mechanical defects. The recorded mileage of 55,199 miles against a 17-year vehicle age equates to roughly 3,247 miles per annum, which is exceptionally low even by Smart Fortwo standards. This level of usage typically indicates either a second or third household car used only for short urban trips, a vehicle that has spent significant periods off the road, or a car that has covered most of its mileage in heavy traffic stop-start conditions rather than sustained running. The two-day gap between the failed test on 21 March 2023 and the subsequent pass on 23 March 2023 strongly suggests a quick retest after addressing minor issues, consistent with a car that is used sparingly and serviced reactively. Low annual mileage of this magnitude on a diesel Smart Fortwo means the engine, diesel particulate filter, and turbo components are far closer to their original specification in terms of mechanical wear than the calendar age would suggest, but it also raises concerns about prolonged standing periods which can affect seals, battery condition, and brake component corrosion. From a mechanical inspection standpoint, the absence of any structural advisories across the available test history is encouraging for a vehicle of this age and rear-engined layout, though it does not eliminate the possibility of subframe or rear crash structure corrosion developing since the last test. On a physical inspection, particular attention should be paid to the rear subframe mounting points, the suspension trailing arms and bushes which carry the full weight of the powertrain, and the rear brake calipers which are prone to seizing when a vehicle sits idle for extended periods. A test drive should include firm braking from moderate speed to check for any rear brake binding or judder, and the vehicle should be driven over uneven surfaces to listen for clonks or knocks from the rear suspension, which on the Fortwo is often the first indicator of worn linkages or perished bushes. Steering response should be checked for vagueness or wandering, as the Fortwo's relatively narrow track can mask worn front components until significant deterioration has occurred. The diesel powertrain itself warrants specific checks given the low-mileage usage pattern. The CDI engine is known for actuator and injector wear at higher mileages, but at 55,199 miles the more relevant concern is whether the diesel particulate filter has completed sufficient regeneration cycles to remain clear, or conversely whether short journeys have caused premature filter loading. During a test drive, the engine should be allowed to reach full operating temperature and revved through the range to ensure smooth power delivery without excessive smoke, hesitation, or warning lights on the dashboard. The automated manual transmission, a known weak point on these vehicles, should be observed for smooth clutch engagement, prompt gear changes without flare or shunt, and any unusual whine from the transmission tunnel area. Given the test history suggests the car is fundamentally roadworthy but has had intermittent compliance issues, a pre-purchase inspection by a Smart specialist would be prudent to verify the condition of the rear structure and clutch actuation system which are expensive to rectify but not flagged in standard MOT testing.
