Spanner can help turn your car details into an advert.
Could suit you if…
- You regularly make longer journeys: diesel may fit that pattern better than a routine of mostly short trips. Compare actual running costs.
- You often load a pushchair, dog or bulky bags: an estate layout could be useful. Try your own luggage rather than judging by the exterior size.
- You would prefer less gear changing in traffic: the recorded automatic transmission may suit. Try how this exact gearbox behaves on a test drive.
Think twice if…
- You need room for several children or extra passengers: the seat count is not recorded. Confirm this exact version's seats and child-seat fit; do not assume from the model name.
- Most journeys are short school runs or local trips: check whether this diesel has a particulate filter and what longer runs its handbook requires.
- You need servicing to fit a tight budget: Spanner estimates higher maintenance costs for this type. Get quotes for the exact engine and gearbox before committing.
This is general guidance about this type of car and your needs — not an inspection or approval of this individual car.
Most 2018 3 Series diesels are the 2.0-litre four-cylinder B47 units fitted to saloon and Touring models and use BMW's ZF 8-speed automatic — both are common and parts are widely available in Ireland. Expect diesel-specific items: a DPF and EGR system that can clog if the car has mostly done short urban trips, and an automatic gearbox that benefits from documented fluid/filter servicing. The Touring/estate body gives a significantly larger boot and useful roof-rail or mounting options for family kit.
- DPF behaviour and recent regens — look for frequent warning lights, long-run history or soot smell after hard drives
- Automatic gearbox operation and service history (smooth shifts, no hesitation or jerking; ask for a transmission fluid/filter change record)
- EGR/intake carbon build-up (hesitation, loss of low-end power) and turbo condition (no blue/black smoke under acceleration)
- Rear tailgate seals/struts and boot floor for water ingress or corrosion, plus rear suspension for sag if the car has carried heavy loads
- Signs of oil leaks or excessive oil consumption and evidence of regular oil changes (timing-chain engines tolerate neglect poorly)
