This is the F30-generation 3 Series introduced in 2012, typically fitted with a 2.0-litre diesel in Irish market examples (commonly badged 318d/320d) and manual gearboxes were common. Some of the 2.0 diesels from this era used the N47 family which can show timing-chain/tensioner wear if oil/service intervals were neglected; DPF and EGR clogging is also common if the car has mostly done short urban trips. Expect reasonable parts availability in Ireland and cheaper servicing at independent BMW specialists rather than main dealers.

• Cold-start and idle for a rattling/ticking from the engine (timing-chain/tensioner symptom on some 2.0 diesels).
• DPF condition and recent long-run/regen history — heavy city use can mean an expensive DPF clean or replacement.
• Clutch bite point and pedal free-play for signs of heavy wear or recent replacement (manual gearboxes on 13-year-old cars commonly need attention).
• Look for oil leaks around the turbo/HPI pump and check for smoke on boost (turbo and high-pressure fuel system wear signs).
• Suspension bushes, front wishbones and rear trailing-arm mounts for wear or corrosion, plus underbody and wheel-arch rust given Irish road exposure.
