FAULT 118002 - MIXTURE TOO RICH SETS DURING WINTER WITH COLD AMBIENT TEMPERATURES What's New: ? In the Warranty Information section: defect code, labor operations and additional information are updated . The Service Engine Soon (MIL) light is on with the following fault stored in the DME. ? Fault: 118002 - Mixture too rich In the situation being described, the fault is only stored during the \"\"cold winter months along with the use of winter fuel.\"\" Various other causes for a rich mixture fault are possible and should not be overlooked. CAUSE ? DME software diagnostic is too sensitive ? This situation is most likely to occur if the driving profile is one of frequent cold engine starts and/or primarily short distance trips (idle / low load operation) where full engine operating temperature is not reached. ? Due to the lower engine oil temperatures crankcase vapors that contain a higher fuel content are not completely drawn off via the crankcase ventilation system. ? A false DME adaptation routine could then lead to this fault being set.\"","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10146613-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10146613-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10146613","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MINI","model":"CLUBMAN","year_from":2017,"year_to":2017,"match":"exact","vehicle_ids":["2017_mini_clubman"]},{"make":"MINI","model":"COOPER","year_from":2014,"year_to":2015,"match":null,"vehicle_ids":[]},{"make":"MINI","model":"COOPER","year_from":2017,"year_to":2017,"match":null,"vehicle_ids":[]},{"make":"MINI","model":"COOPER CONVERTIBLE","year_from":2016,"year_to":2016,"match":"exact","vehicle_ids":["2016_mini_cooper-convertible"]},{"make":"MINI","model":"COOPER S","year_from":2014,"year_to":2017,"match":null,"vehicle_ids":[]},{"make":"MINI","model":"JOHN COOPER WORKS","year_from":2015,"year_to":2017,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
