2017 Vauxhall Astra 1.6L Diesel · FJ66 BFU

The 1.6 CDTI diesel Astra typically returns around 55-65 mpg on a mixed run, though real-world figures from owners often sit nearer 50 mpg. Road tax (VED) for a car of this engine size, registered between 2017 standards, usually falls into a moderate band, but you should verify the exact rate using the current VED bands against the listed CO2 figure on the V5C. Insurance for a 2017 Astra 1.6 diesel is generally in group 15-18, which is reasonable for the family hatchback class.

Routine maintenance for this engine is straightforward, with oil and filter changes typically costing £120-£180 at an independent garage. Diesel Astra servicing is generally affordable compared with premium rivals, though parts such as the dual-mass flywheel and DPF can be costly if they fail. Tyres are a regular expense at roughly £50-£80 per corner for budget brands. Based on fuel, tax, insurance, and routine servicing, expect annual running costs in the region of £1,200-£1,500 depending on mileage and location.

Because the MOT history shows only one failure without a recorded defect category, focus your inspection on items that frequently cause Astra 1.6 CDTI failures: check the front brake discs and pads for wear, examine the rear suspension components for corrosion, and look closely at the exhaust system for DPF and EGR-related warning lights on a diagnostic scan. The car's odometer reading of 82,237 miles at the most recent test means timing belt service is a critical question — confirm whether the cambelt and water pump have been replaced on schedule, as neglect leads to engine damage.

On the road, listen for diesel knock on cold start and watch for excessive smoke from the exhaust, which can indicate injector wear or DPF issues common to this engine family. Inspect the underside of the car on a ramp if possible, paying attention to the subframe mounting points, anti-roll bar bushes, and rear axle beam — all known Astra weak spots. Finally, check the climate control and infotainment system for faults, and ensure all electrical features function, as wiring issues have been reported on Astras of this generation. A pre-purchase inspection by a Vauxhall specialist or the AA/RAC costs around £150-£250 and is strongly recommended given the gap between mileage intervals in the MOT record.
