2012 Smart Fortwo Passion CDI Auto 0.8L Diesel · A20 XDJ

This Smart Fortwo presents a stable and improving maintenance trend, culminating in a clean pass on 15 January 2026 at 119,895 miles with zero defects. That result is significant because it follows a failed test just two days prior on 6 January 2025 at 119,230 miles, where the tester flagged four serious issues: an excessive engine oil leak, a fractured offside front coil spring, an excessively binding offside rear service brake, and a corroded offside rear brake pipe obscured by grease. The fact that the subsequent 2025 and 2026 tests passed cleanly indicates those defects were addressed rather than ignored, which is a positive signal about the most recent keeper's approach to upkeep. The mileage pattern is remarkably flat. Between the May 2023 test at 118,110 miles and the January 2026 test at 119,895 miles, the car covered just 1,785 miles over nearly two years and eight months. That is an unusually low accumulation, suggesting the vehicle saw very light use or possibly stood idle for extended periods during that window. The annualised average of roughly 8,564 miles across its fourteen-year life is typical for the segment, but the recent plateau raises a question about prolonged sitting, which can cause brake seizure, tyre flat-spotting, and dried-out seals. A buyer should focus the in-person inspection on the components that have historically caused failures. The offside rear braking system is the most persistent concern, having appeared as binding in December 2022, excessively binding in January 2025, and accompanied by a corroded brake pipe. That pipe should be examined closely for ongoing corrosion, particularly where it may have been coated over rather than properly replaced. The fractured offside front coil spring from the 2025 failure also warrants a thorough check of both front springs and the condition of the suspension bushes and dampers, looking for any signs of uneven ride height or fresh replacement parts. The engine oil leak that caused the 2025 failure should be verified as fully resolved by inspecting the engine underside and bell housing for fresh residue. Given the extended period of low mileage accumulation, tyre condition, brake disc surface corrosion, and the condition of all flexible hoses and seals deserve careful attention, as sitting vehicles often develop deterioration that a clean MOT does not always reveal.
