2 known faults with sources

B-engine coolant leaks and EGR coolerCooling / EGR

Engine / equipment: B47 and B57 diesel and B48 and B58 petrol modular engines (BMW from 2014–2015 and MINI from 2014)
Period mentioned: 2014–2026
Symptoms: Coolant loss with a low-level warning, coolant or oil residue at the rear of the engine; on diesels, internal coolant loss with no visible leak (EGR cooler).
Possible cause described: On the B48 and B58 the water pump leaks (from its weep hole) and the oil filter housing with heat exchanger can crack; on 2017–2021 B58s the crankcase ventilation valve also fails. On the diesels the EGR cooler can leak internally and mix coolant with soot: BMW issued a recall over the risk of the intake manifold catching fire.
Check for the garage: Check the coolant level, look for leaks under the water pump and at the oil filter housing, and on diesels confirm by VIN whether the EGR cooler campaign was done.
Cost cited in the source: Water pump: relatively cheap to replace; oil filter housing: more labour-intensive; EGR cooler: free if covered by the campaignA rough figure from the original database, not an up-to-date quote.

Mileage cited in the database: 80,000–195,000 km. This is not a maintenance interval and does not predict a failure.

Applies if: Weak points of this model from inspections, breakdown statistics and recalls; anything specific to one engine is stated in the sheet.

Engine mounts, wet boot and campaigns on the MINI F55/F56/F57Known weak points

Engine / equipment: Third-generation MINI F55, F56 and F57 (petrol, diesel and Cooper SE)
Period mentioned: 2014–2024
Symptoms: Knocking from the engine bay due to engine mounts and a torque strut worn at low mileage; water in the boot and spare-wheel well of the F56; at inspection, headlights and handbrake and service brake; on petrols, carbon on the injectors and intake at high mileage; on the B37/B47 diesels, particulate filter, dual-mass flywheel, turbo, EGR and injectors.
Possible cause described: The German guide finds the B38/B48 and B37/B47 engines reliable; in the ADAC statistics the MINI is always green. Recalls: the spare-well bracket nut (2013–2014), seat height adjustment (August–September 2014), airbags (about 200 cars from 2016) and glycol leaking from the EGR cooler with a fire risk on the four-cylinder diesels (April 2015–September 2016).
Check for the garage: Listen for knocks when accelerating and lifting off; lift the boot floor; check campaigns by VIN.
