2017 Vauxhall Astra 1.0L Petrol · BU67 OER

The 1.0T petrol engine is relatively frugal, typically returning 50-55 mpg on a mixed cycle according to manufacturer figures, giving monthly fuel costs of around £100-£130 for average users. Road tax falls into a reasonable bracket for a sub-1.0-litre turbo and insurance is competitive in low-to-mid groups for this engine. Maintenance costs for the Astra 1.0T are modest at independent garages, though timing chain and turbo failures have been reported on early units, so a thorough check is worthwhile. Estimated annual running costs including fuel, tax, insurance and routine servicing should sit in the £1,400-£1,700 range, depending on mileage and location.

Begin with a close look at all four tyres and confirm the fronts have legal tread, as the March 2026 advisory flagged both front tyres as worn close to the limit. The TPMS light being illuminated at the last MOT suggests a sensor fault or incorrect pressures, so check all four sensors and consider whether a reset is needed. Inspect the front brake discs for corrosion ridges and the rear pads for remaining material, given the 2025 advisories, and factor replacement into any offer. On the 1.0T engine specifically, listen for timing chain rattle on cold start, check for oil leaks around the turbo and cam cover, and confirm the coolant has been changed on schedule. Finally, examine the offside rear indicator area carefully, as this failed in March 2024, and verify the wiring and bulb holder are sound.
