BMW 3 Series2017

• Solid diesel engine power and excellent fuel economy for motorway commuting, but urban use invites DPF trouble.
• At €20k median, prices have risen sharply year-on-year; check comparable 2016–2018 rivals before committing.
• DPF blockages, turbo carbon build-up, and EGR stiction are common on this generation—especially if previous owner did short trips. Budget €1,500+ for turbo work if needed.
• Before buying, request full service history and ask the seller whether DPF regeneration warnings appeared; have a pre-purchase diesel diagnostic scan done (€150–€200).
• High median mileage (182k km) is typical for a 9-year-old Irish diesel—inspect exhaust for black smoke and listen for turbo whistle on test drive.
