WHILE DRIVING IN WET WEATHER CONDITIONS, CONDENSATION MAY BUILD UP WITHIN THE ENGINE CHARGE AIR RADIATOR. FOLLOWING A RAPID INCREASE IN ENGINE SPEED, THIS CONDENSATION COULD BE DRAWN IN TO ONE OF THE ENGINE’S CYLINDERS, CAUSING THE ENGINE MANAGEMENT SYSTEM TO SENSE A MISFIRE. THE ENGINE IS PROGRAMMED TO REACT TO THIS MISFIRE BY INITIATING A RESTRICTED PERFORMANCE MODE TO PROTECT THE EXHAUST CATALYST. IN THIS MODE, THE DRIVER NOTICEABLY EXPERIENCES REDUCED POWER TO ACCELERATE UNTIL THE ENGINE IS SWITCHED OFF AND THEN RESTARTED. FURTHERMORE, AN ENGINE WARNING MESSAGE WILL DISPLAY IN THE INSTRUMENT CLUSTER MESSAGE CENTER AND THE ENGINE MALFUNCTION INDICATOR LAMP MAY ILLUMINATE. NEW COMPONENTS HAVE BEEN DESIGNED TO LIMIT CONDENSATION FROM BUILDING IN THE ENGINE’S CHARGE AIR RADIATOR TO PREVENT THE RESTRICTED PERFORMANCE MODE FROM INITIATING. ADDITIONALLY, UPDATED ENGINE CONTROL MODULE (ECM) SOFTWARE HAS BEEN DEVELOPED WHICH CHANGES THE THRESHOLDS NECESSARY TO INITIATE THE RESTRICTED PERFORMANCE MODE FOR THIS ISSUE.\"","document":null,"url":"https://open.wenmarpro.com/bulletins/10102941","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"engine","name":"Engine","parent":null},{"id":"software","name":"Software","parent":"electrical"}],"codes":[],"topics":[],"vehicles":[{"make":"LAND ROVER","model":"RANGE ROVER EVOQUE","year_from":2012,"year_to":2013,"match":"exact","vehicle_ids":["2012_land-rover_range-rover-evoque","2013_land-rover_range-rover-evoque"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
