BMW 3 Series2022

• Median mileage of 109k km significantly exceeds Irish average for this age—check service history and motorway vs. city driving split before committing.
• Diesel particulate filter (DPF) regeneration problems common, especially if previous owner did short urban trips; inspect service records for forced regens or limp-mode incidents.
• EGR valve carbon accumulation typical at 40k–60k miles—budget for potential cleaning or replacement if idle roughness or hesitation detected during test drive.
• Timing chain rattle on cold start confirms known B47 engine design flaw; listen carefully on first ignition and obtain full service records proving no prior issues.
• Prices stable year-on-year but market spread wide (€6k+)—negotiate hard on higher-mileage examples; petrol 3 Series may offer better residuals without DPF headaches.
