This is the Astra K-era compact hatchback (2015–2021) most commonly seen with the 1.6 CDTi diesel and a five-speed or six-speed manual. Diesel Aspiras are very efficient on long runs but can suffer blocked DPFs and EGR/turbo carbon build-up if they’ve been used mainly for short town journeys; the manual clutch can also need replacement on high-mileage examples. Parts are common and inexpensive in Ireland, and many examples come with sensible spec levels rather than expensive extras.

• DPF / regeneration history — any recent forced regenerations, frequent warning lights or lots of short-trip evidence (town use) that would indicate a clogged DPF
• Turbo/EGR behaviour — look for black smoke on hard acceleration, noisy turbo spooling or a laggy throttle response
• Clutch condition and gear engagement — check for slipping, a high biting point or noisy synchromesh when changing gears
• Oil leaks and intercooler/boost hose condition — look under the turbo area and around the charge pipes for oil residue
• Rear arches and underbody corrosion — check suspension mounts and wheelarches for rust, especially on Irish salted roads
