2017 Mazda 6 2.2L Diesel · SC66 OSB

The most recent DVSA roadworthiness examination was conducted on 5 January 2026, at which the vehicle was awarded a clean pass with no defects, advisories, or minor issues recorded. Looking back through the documented history, every test since December 2021 has returned a similarly clean pass, with no recorded advisories, monitor items, or failures across any of the five inspections available. This represents a particularly consistent and stable maintenance and compliance pattern over a five-year span. A clean advisory record on a nine-year-old Mazda 6 suggests that the previous keeper has been attentive to preventative maintenance, addressing wear items before they become MOT-relevant defects. While a clean MOT history is a strong indicator of general upkeep, it is worth noting that the MOT test is a point-in-time roadworthiness check rather than a comprehensive mechanical inspection, and items such as clutch wear, cambelt condition, and internal engine health are not assessed under the test regime. In terms of recorded mileage, this Mazda 6 has covered 85,947 miles over nine years, equating to roughly 9,550 miles per year on average. This is broadly typical for a vehicle of its age and class, suggesting it has been used as a regular daily driver rather than being left standing for extended periods or subjected to excessively high mileage accumulation. The MOT history reveals consistent annual testing with no prolonged gaps that might indicate the vehicle was off-road or unused for any meaningful duration. Typical-mileage usage of this nature usually translates to predictable wear patterns on consumables such as brake pads, brake discs, tyres, and clutch components, rather than the corrosion and perishing issues commonly associated with low-mileage or stored vehicles. At nearly 86,000 miles, the diesel or petrol engine, transmission, and turbocharger (if fitted) should still have substantial service life remaining provided the documented service schedule has been followed, particularly with attention to cambelt replacement intervals for the petrol 2.0 and 2.5 Skyactiv units, which typically require renewal between 60,000 and 100,000 miles depending on specification. Given the clean MOT record, the prospective buyer should focus on age-and-mileage-appropriate items that fall outside the scope of standard MOT testing but are nonetheless critical to long-term reliability. The first physical inspection priority should be the tyres: check the sidewalls carefully for perishing or cracking, as rubber compounds degrade with calendar age regardless of tread depth, and verify that all four tyres are of matching size, type, and similar tread depth to prevent transmission and handling irregularities. Examine the wheels for any kerbing damage and inspect the brake discs for signs of corrosion on the inner and outer edges, particularly if the vehicle has been subject to any short-trip or coastal use. On a road test, listen for any clonking or knocking from the front suspension over uneven surfaces, which could indicate worn anti-roll bar bushes, drop links, or bottom arm bush deterioration common to this Mazda 6 generation. Brake pedal feel should be firm and progressive without any sponginess suggesting air ingress or master cylinder wear, and the steering should be precise without vibration or pulling to either side under braking, which could point to warped front brake discs. Beyond the rolling components, attention should be given to time-based servicing items that do not necessarily correlate with mileage. The 12-volt battery should be load-tested, as Mazda auxiliary batteries in this age range commonly suffer from reduced capacity due to repeated short journeys and parasitic drain, and a failing battery can cause erratic electrical behaviour and start issues. Inspect all fluid levels and their condition: engine oil on the dipstick should be amber to dark brown without any milky residue suggesting coolant contamination, while the coolant itself should be checked for proper concentration as Mazda Skyactiv engines require specific long-life OAT coolant to prevent internal corrosion of the aluminium block and cylinder head. The transmission fluid, whether manual or automatic, should be checked for smell and colour, as automatic gearbox fluid in particular darkens and degrades over time. Finally, verify the service book history and request evidence of cambelt replacement if not already documented, as the 2.0 Skyactiv-G petrol unit in particular has a manufacturer-specified replacement interval that, if missed, risks catastrophic engine damage. A compression test and an OBD scan for stored fault codes would also be prudent given the vehicle's age and would provide additional reassurance beyond the clean MOT record.
