4 known faults with sources

Engines: 18i / 20i (Petrol) · 18d / 20d (Diesel) · 25e / 30e (Plug-in hybrid) · iX1 (Electric)

Applies if: Only cars built from 18/6/2025 to 25/8/2025; confirm by VIN.

Incorrectly made seat belts (2025 X1, iX1, X2 and iX2)Known weak points

Engine / equipment: BMW X1 and iX1 (U11) and X2 and iX2 (U10) built from 18/6/2025 to 25/8/2025
Period mentioned: 2025
Symptoms: No symptoms in everyday use: the fault only shows in a crash, when the belt restrains less than it should.
Possible cause described: According to alert 41/2025 of the European Safety Gate system (SR/03496/25), the seat belts were not made correctly and, in a collision, their restraint function may be reduced, increasing the risk of injury. About 8,800 cars worldwide are affected (2 Series, X1, iX1, X2 and iX2; BMW campaigns 0072800200, 0072790200 and 0072780200).
Check for the garage: Check by VIN at a BMW dealer whether your car is in the campaign and whether the belts have been replaced.
Cost cited in the source: Free under the recall.A rough figure from the original database, not an up-to-date quote.

Engines: 18i / 20i (Petrol) · 25e / 30e (Plug-in hybrid)

Applies if: The 1.5 three-cylinder in this generation is still a B38 family engine (mild-hybrid on some versions).

Applies if: The plug-in hybrids in this range pair the 1.5 B38 with an electric motor; the sheet covers the petrol part.

Crankshaft thrust bearing and carbon on the 1.5 three-cylinder (B38)Engine

Engine / equipment: 1.5 three-cylinder B38 (also in the plug-in hybrids): BMW 1 Series, 2 Series Active Tourer, X1, X2 and MINI
Period mentioned: 2014 onwards
Symptoms: On early engines with a manual gearbox, crankshaft thrust-bearing damage that can end in serious failure; over the years, loss of power and higher consumption from carbon in the intake, valves and injectors.
Possible cause described: The half-shell thrust bearing was too weak; a 360-degree one has been fitted since April 2015. BMW issued no recall but offered goodwill repairs. The German guide sees no chain problems and says early oil consumption has largely disappeared; the petrol particulate filter (from March 2018) rarely causes trouble.
Check for the garage: On engines before April 2015 with a manual gearbox, ask BMW whether the bearing upgrade was done and listen for crankshaft noises; use quality fuel and inspect the intake if power drops.
Cost cited in the source: No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.

Engines: 18d / 20d (Diesel)

Applies if: Only the B47 (diesel) and B48 (2.0 petrol) engines; the 1.5 three-cylinder (B38) is not covered.

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.

Engines: iX1 (Electric)

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.
