Our Verdict
This 2017 Mazda 6 diesel is a reasonable buy for a high-mileage used car, with a clean MOT record across the last five years. However, the very high mileage means you should budget for wear-and-tear items and verify service history before purchase.
Given the high recorded mileage of nearly 177,000 miles, prioritise a full service history to confirm timing belt, cam belt, and diesel particulate filter (DPF) intervals have been met on this 2.2-litre diesel. The MOT history shows no advisories across five years, which is unusual at this mileage and worth probing — ask the seller for proof of regular maintenance rather than relying on the clean test record alone. Negotiate on price reflecting the mileage; comparable lower-mileage 2017 Mazda 6 diesels will command a premium, so use the odometer reading as leverage.
As a 2191cc diesel, this Mazda 6 will typically return strong fuel economy on longer journeys, though urban use may increase DPF-related costs. Road tax for a 2017 diesel of this size is likely in a higher CO2 band, and insurance group will reflect a family saloon/estate rather than a performance car. Annual running costs including fuel, tax, insurance, and maintenance for a high-mileage example are estimated at £1,200-£1,500 given the need for more frequent servicing and consumables.
The MOT history shows no failures or advisories on this vehicle, so there are no specific failure types from the record to check — but at 176,995 miles, inspect brake discs and pads, suspension bushes, and tyre condition closely as these wear with use. For the 2.2-litre Mazda diesel, check for smoke on start-up, DPF warning lights, and any oil dilution issues common to high-mileage oil-burner use, even though none were flagged at MOT. Verify the silver bodywork for corrosion or accident repair, and confirm the odometer reading matches the 2026 MOT figure of 176,995 miles.
The vehicle (NV17LCN) is a silver 2017 Mazda 6 with a 2.2-litre diesel engine, first registered in July 2017. MOT history shows five consecutive passes from 2022 to 2026 with no defects recorded at each test, the most recent being on 2026-07-10 at 176,995 miles. The lack of any MOT failures is a positive sign, though the mileage is well above typical for an eight-year-old car. No aggregate model reliability data was available to compare against, so assessment rests on the individual history provided.
No aggregate MOT reliability data was available for the Mazda 6, so this assessment is based solely on the individual vehicle's test history.

- 2.2 Diesel Carbon BuildupModerate
Soot accumulates in the intake manifold and EGR system, causing flat performance, poor economy and repeated regeneration trouble.
- 2.2 Skyactiv-D Twin-Turbocharger Wastegate and Bearing FailureSerious
On 2.2-litre Skyactiv-D (SH-VPTS) diesel engines, the sequential twin-turbocharger assembly suffers from mechanical failure of the exhaust gas regulation valve (wastegate flapper) inside the turbine housing. The pivot pin and rivet holding the flapper fatigue and shear off, causing sudden loss of boost pressure at lower RPMs and triggering fault code P0299 (turbocharger underboost) alongside severe limp mode. In addition, turbocharger bearings are vulnerable to oil starvation caused by carbonised oil and soot accumulation from DPF regeneration cycles. Replacing the twin-turbo unit requires a revised assembly, new oil feed pipes and thorough oil flush.
- 2.2 Skyactiv-D Injector Copper Washer Blow-By and Oil Pickup BlockageSerious
The 2.2 Skyactiv-D engine is prone to premature erosion of the copper combustion chamber sealing washers beneath the fuel injectors. When a washer fails, high-pressure combustion gas blows past the injector into the rocker cover, rapidly baking the engine oil into hard carbon crust and granular sludge. This carbon debris migrates down into the oil sump and chokes the fine wire-mesh oil pump pickup strainer. Oil starvation follows, triggering low oil pressure warnings, grinding exhaust camshaft lobes, vacuum pump failure (causing stiff brake pedals) and catastrophic engine seizure. Preventative replacement of injector washers and sump strainer cleaning is essential.
