2 known faults with sources
Engines: Cooper C / S (B38/B48) (Petrol)
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: Only cars built from June 2022 to 2024; confirm by VIN.
Integrated braking system (IBS) that can fail: ABS and DSC out of action and a hard pedalElectrical and electronic systems
- Engine / equipment
- BMW X1 and iX1 (U11), 2 Series Active Tourer (U06), 5 Series and i5 (G60), 7 Series and i7 (G70), X5, X6, X7, XM; MINI Cooper (F66 and J01) and Countryman (U25)
- Period mentioned
- 2022–2024
- Symptoms
- The brake warning lights and a screen message come on; the pedal needs more force; ABS and stability control stop working.
- Possible cause described
- BMW recalled more than a million cars built from June 2022 over a supplier’s integrated braking system (Continental’s MK C2, according to the press): interference in its electronics, or broken welds in its servomotor according to the US recall, can make the pedal harder and leave the car without ABS or DSC. The whole system is replaced in about 3.5 hours (KBA 13586, BMW campaign 0034670200); there were waits of months because of parts shortages.
- Check for the garage
- Check campaign 0034670200 by VIN at a BMW or MINI dealer; if the brake warning appears, go to the garage straight away.
- Cost cited in the source
- Free under the recall.A rough figure from the original database, not an up-to-date quote.
