Replacing the Windscreen J01 J05
For affected vehicles the interior mirror mounting plate may not have been bonded to the windscreen sufficiently. The rear view mirror could become partially or even completely detached from the windshield.
Fix: The windscreen (including interior mirror mounting) will be replaced.
Recalled models: MINIe 3Dr Hatchback · 18 vehicles
Check the Interior Mirror Holder Replace if Necessary
The Safety Recall relates to the interior rear-view mirror. The interior mirror mounting plate may not have been bonded to the windscreen sufficiently. Due to an insufficient adhesive surface on the mounting plate (bracket) the rearview mirror could become partially or even completely detached from the windshield. If the rearview mirror becomes partially or even completely detached this could impair the visibility while driving. In the event of an accident this could increase the risk of injury.
Fix: The windscreen will be replaced on all vehicles.

Software fault in crankshaft sensor
The affected vehicles may be equipped with a crankshaft sensor with a software fault.
Fix: On the affected vehicles the crankshaft sensor will be replaced with a new version.
Recalled models: MINI · 1,642 vehicles
Software fault with crankshaft sensor
The affected vehicles may be equipped with a crankshaft sensor with a software fault. The crankshaft sensor cannot process the signal values from the crankshaft transmitter due to an improper firmware level. The firmware does not compensate sufficiently the temperature gradients and the magnetic field strength of the sensor electronic. If the crankshaft sensor cannot process the signal values from the transmitter the Digital Diesel Electronic (DDE) will notice that and change to the emergency operation mode. The emergency mode will be displayed by the check control message �engine malfunction�. The driver may notice a rough running engine and a reduced driving power (70%). However an engine stalling during driving conditions cannot be excluded.
Fix: On the affected vehicles the crankshaft sensor will be replaced with a new version.
Recalled models: MINI · 4,025 vehicles

Fix: Where necessary replace affected airbag modules.
Recalled models: MINI · 668 vehicles
Front seat backrest may not fully engage
The back-rest adjustment mechanism on both front seats may be incorrectly set and display a large amount of play. This can cause the back rest to wobble and in the event of an accident the back rest may inadvertently fold backwards.
Fix: On affected vehicles adjust back rests to manufacturer's specifications.
Recalled models: MINI · 2,836 vehicles
Spare wheel may become loose
The emergency spare wheel mounting may gradually loosen due to vibration. If the flange nut loosens completely the emergency spare wheel well with the spare wheel can suddenly separate from the vehicles underbody.
Fix: Recall the vehicles that are likely to be affected to replace the flange nut on the mounting plate of the emergency spare wheel well.
Recalled models: MINI · 1,163 vehicles
Fire may occur
Some engines are fitted with an additional water pump for the turbo charger. In single cases an overheating of the circuit board can occur. A short-circuit to earth may cause the melting of the plug connections and the housing. Further heat development may then lead to scorch damage. In exceptional cases such overheating can lead to smouldering of the water pump. If smouldering occurs an engine compartment fire and vehicle fire cannot be excluded.
Fix: The water pump will be replaced for a new more robust version.
Recalled models: MINI John Cooper Works · 30,149 vehicles
Brake performance could be affected
It is possible that the vehicle has been fitted with 16 inch front brake discs instead of the required 17 inch brake discs. If this is the case extreme braking could result in the over heating of the brake system and introduce vapour (air) bubbles into the brake fluid. This could affect the braking performance.
Fix: Recall all potentially affected vehicles and check the size of the brakes discs on the front axle. If 16 inch brake discs are found replace these with the correct 17 inch brakes discs and brake pads.
Recalled models: MINI John Cooper Works · 260 vehicles
Directional control may be lost
The front axle inside control arm ball joint may not be torqued to the correct specification which can have a strong negative influence on wheel alignment. In extreme cases should the screw connections become undone whilst the vehicle is in motion then directional control maybe lost.
Fix: Recall all affected vehicles to have the subject connections torqued to the correct specification.
Recalled models: R52 · 13 vehicles
Directional control could be lost
The Anti - Roll Bar fitted to the rear axle has too large a diameter. Detachment may occur with loss of directional control
Fix: Recall affected vehicle and replace Anti - Roll Bar.
Recalled models: MINI · 163 vehicles
Handbrake may self release
