Recalls: Mini R58 Coupe
Overview
Manufacturers, or importers, issue recalls for defects or faults which have the potential to cause injury. Generally, manufacturers will inform the original buyers if their vehicle is subject to a recall and of the steps required to remedy the defect or fault. Please note that the recalls below (if any) are for Australian-delivered vehicles only. Furthermore, the number of recalls should not be taken as an indication of a model’s reliability or its safety more generally.

MINI R58 JCW Coupe: N14 engine, carbon deposits and misfires
For the MINI R58 John Cooper Works Coupe, the 1.6-litre turbocharged N14 petrol engine is susceptible to developing carbon deposits on the back of the intake valves. Since direct injection engines such as the N14 do not spray fuel on the backside of the intake valves, the detergent properties of the fuel cannot remove the carbon build up (as occurs in port injected engines).
In September 2012, MINI issued Service Information Bulletin SI M12 02 10 for MINI R55/R56/R57/R58/R59 Cooper S models that had N14 engines. According to the service bulletin, vehicles with excessive carbon deposits on the intake valves/ports may exhibit the following symptoms –
- Illumination of the ‘Service Engine Soon’ (MIL) lamp;
- Rough running when the engine is cold or warm; and,
- The following misfire faults: 2771, 2772, 2773, 2775, 2776, 2777, 2779, 277A, 277B, 277D, 277E, 277F – ‘Combustion misfire, cylinder 1..4’. This may appear with faults 2781, 2782 or 2783 – ‘Combustion misfire, multiple cylinders’.
The engine may also be difficult to start or not start at all.
The service bulletin recommended that ‘BMW Group Carbon Blaster’ (part number 81 29 2 208 034) be used to clean the carbon deposits. As a preventative measure, MINI USA recommended that ‘BMW Group Fuel Injection and Induction System Cleaner’ be used annually on N14-powered vehicles to prevent carbon buildup.
For the related MINI R58 Cooper S Coupe, the N18 engine had an updated positive crankcase ventilation (PCV) system whereby the vacuum line was internal to the valve cover, presumably to reduce the propensity for oil particles to pool in the intake manifold. Notwithstanding this design change, the N18 engine should also be regarded as being susceptible to carbon deposits.
MINI R58 Coupe: thermostat housing coolant leak and P0597
For the MINI R58 Cooper S and JCW Coupes (powered by the turbocharged ‘Prince’ petrol engines), the plastic thermostat housing can become brittle over time and develop hairline cracks which allow coolant to leak and pool on top of the transmission – these leaks often become apparent after 80,000 kilometres, though individual experiences may vary. As a result of the coolant leakage,
- Diagnostic Trouble Code (DTC) ‘P0597 Cel:Thermostat Heater Control Circuit/Open’ may be stored because the coolant temperature sensor no longer functions;
- The engine may take longer to reach operating temperature; and,
- The engine may overheat.
MINI R58 Cooper and Cooper S Coupe: oil leak from oil pump solenoid
In January 2014, MINI issued Service Information bulletin SI M11 01 12 for R58 Cooper and Cooper S Coupes (with N16 and N18 engines, respectively) that were produced up to January 2013. According to the service bulletin, a small engine oil leak may be visible from the underside of the engine – this was attributed to the internal sealing of the oil pump volume control solenoid valve being ‘compromised’, allowing engine oil to leak from the oil pump volume control solenoid. To fix, the oil pump control solenoid valve (part number 11 41 7 585 446) had to be replaced.
According to the bulletin, engine oil could migrate inside the electrical harness, such that it was necessary to inspect the electrical connector for oil. If present, the DME cover was to be removed and all three electrical connectors were to be removed from the DME so that those connectors could also be inspected. If engine oil was present in the DME connector, the engine section of the wire harness and the DME also required replacement.
2012 MINI R58 Coupe: false readings from engine coolant temperature sensor
In January 2013, MINI issued Service Information bulletin SI M17 07 12 and Service Information bulletin SI M17 08 12 for R58 Coupe vehicles that were manufactured prior to March 2012 and powered by the N14, N16 or N18 engines. According to the service bulletins, the engine coolant temperature sensor could experience internal corrosion which could lead to internal bridging of the contacts and inaccurate engine temperature readings. In turn, these false engine temperature readings cause difficulty starting the engine and/or illumination of the ‘Service Engine Soon’ lamp.
As part of a Service Action, a replacement engine temperature sensor was to be installed remotely and wired into the vehicle’s engine harness. There were two approved repair procedures for this process –
- Procedure One required replacement of the upper coolant hose with a modified hose that housed a new engine temperature sensor. Furthermore, an adapter harness needed to be fitted to the car to utilise the new sensor; and,
- Procedure Two required the installation of a new engine temperature sensor with integrated wire harness to be installed in place of the thermostat bleeder screw.
This service action, however, did not apply to vehicles that had N16 engines and had previously had a thermostat replaced with part number 11 53 7 534 521.
