SITUATION



MINI has determined that on certain MY 2002-2006, MY2005, and MY2006 vehicles produced during the affected production period, variations in the



crimping process of the oxygen sensor could lead to an electrical failure inside the sensor.



We estimate that only a small percentage of vehicles will actually develop a problem. Vehicles affected may have the Service Engine Soon lamp



(MIL) on, with an oxygen sensor fault stored. When this failure is detected for the first time, a pending fault code is stored inside the DME. Upon



confirmation of the malfunction, the MIL is illuminated.



CORRECTION



In the event that either of the oxygen sensors in a MY 2002-2006, MY2005, and MY2006 Cooper, Cooper S, Cooper Convertible, or Cooper S



Convertible with the W10 and W11 engines were to fail and exhibit the symptoms listed above it should be replaced with the improved part (P/N 11



78 0 872 674).



For oxygen sensor replacement instructions, refer to REP 11 78 510, found in MINI TIS.



PARTS INFORMATION



[NEW] EMISSIONS WARRANTY INFORMATION



As a commitment to our customers and to demonstrate our confidence in our product, MINI will extend the emissions warranty of the oxygen sensor



from 4 years or 50,000 miles to 10 years or 100,000 miles, whichever comes first.
