2009 Smart Fortwo Coupe 0.8L Diesel · SP09 YWT

Intermittent failures across its testing history establish a mixed mechanical footprint for this Smart Fortwo, which secured a standard pass on 2016-04-22 following an initial refusal for a restricted nearside rear brake component and an ineffective wiper. Historical data shows multiple test failures spanning various components, including a broken nearside front coil spring in 2014 and excessive smoke emissions in 2012, alongside recurring advisories for deteriorating front brake hoses, corroding rear brake pipes, and perishing tyres. While subsequent testing records are absent after 2016 in this dataset, the historical trajectory demonstrates that this city car has experienced notable mechanical defects requiring intervention during its active testing life. This 2009 model has accumulated just 22,202 miles over its seventeen-year lifespan, averaging approximately 1,306 miles per year. Such exceptionally low annual mileage points to periods of sporadic use or prolonged stationary storage, a usage pattern that can accelerate degradation in rubber components, seals, and exhaust systems due to moisture accumulation and a lack of regular thermal cycling. While limited mileage typically translates to reduced physical wear on internal drivetrain components, it does not preclude the ageing and perishing of elastomer-based parts, brake lines, and suspension mountings. Prospective buyers must conduct a rigorous physical inspection focusing on the specific parts flagged in past MOT records, starting with the hydraulic and mechanical braking systems. Given the previous advisories regarding slightly deteriorated front brake hoses and a corroded offside rear brake pipe, the entire brake line network should be checked for surface scale and structural integrity, while a test drive should be used to listen for any binding or dragging from the rear drums and to check for firm, progressive pedal travel without excessive free play. The suspension also warrants close scrutiny, checking the front coil springs and surrounding MacPherson strut assemblies for snapping or corrosion, and listening for knocks, clunks, or metallic creaks when negotiating speed bumps or uneven road surfaces. Further mechanical due diligence should be directed toward the exhaust system and emissions output, referencing the 2012 failure for excessive smoke. The exhaust manifold, catalytic converter, and associated mounting brackets should be examined for accelerated internal corrosion, and the engine should be monitored for smooth idling and clean exhaust emissions upon cold starting. Finally, all rubber items, including tyres, wiper blades, and remaining under-bonnet vacuum or coolant hoses, must be visually inspected for cracking, hardening, or perishing stemming from the vehicle's extended periods of low usage.
