2015 Volkswagen Passat 1.6L Diesel · ST15 SFY

The most recent MOT on 21 February 2026 was passed with no recorded defects, and the preceding twelve‑month period shows a consistent pattern of passes apart from a single failure on 25 January 2025 that listed no faults. This suggests the failure was likely administrative rather than indicative of a mechanical problem, and the overall maintenance trend can be regarded as stable with no emerging defects evident in the official record. At 169 485 miles the 2015 Passat has accumulated roughly 15 400 miles per year, well above the average for a vehicle of its age. Such a mileage rate points to substantial wear on all consumable components, particularly the engine’s timing chain, clutch assembly, and the front and rear suspension bushings. High kilometre accumulation also accelerates tyre tread loss, brake pad and disc thinning, and the progressive degradation of engine oil and coolant seals. There are no obvious gaps in the recorded mileage, indicating the car has likely been in regular use rather than stored for long periods. For a prospective buyer the first visual inspection should focus on tyre condition; even if tread depth appears adequate, sidewall cracking or dry rot is common on tyres that have been driven heavily for many years. Examine the suspension for any play in the ball joints, worn rubber bushings, or leaking shock absorbers, and listen for clunking or creaking when the vehicle is pushed over bumps. The brake system warrants close attention: check disc surface for scoring or rust, ensure pads are not excessively thin, and verify that the calipers move freely without binding, as high mileage can lead to seized pistons and uneven wear. Inspect the under‑carriage for corrosion, especially around the exhaust hangers and chassis mounts, and look for any oil, coolant or brake fluid leaks that may have been missed by the MOT. Given the vehicle’s age, a thorough check of time‑sensitive items is essential. Test the 12 V battery for cranking voltage and consider a load test, as batteries over ten years often lose capacity even if they have been regularly recharged. Verify that the service book contains stamps for oil changes, timing‑chain inspections, and coolant flushes at the recommended intervals; the timing chain on a 1.8 L TSI, for example, should have been inspected around the 100 000‑mile mark. Finally, ensure that the transmission fluid (if manual) has been replaced in line with manufacturer guidance and that the clutch pedal feels consistent without excessive free play, as high mileage can mask impending clutch wear until failure. A comprehensive test drive listening for abnormal noises, checking for smooth gear changes, and confirming stable idle will help confirm that the Passat remains mechanically sound despite its mileage.
