Investigations have identified that the V6 3.0L S/C Petrol engine DTC mapping was incorrectly applied to the V8 5.0L S/C Petrol engine variant, which has led to incorrect cylinder identification in a misfire condition. In these instances, the engine Malfunction Indicator Lamp (MIL) would operate as normal but it would be difficult to diagnose the cylinder that is misfiring as all the misfire DTCs are incorrect, except for cylinders 7 and 8 which are not affected.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10116841-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10116841-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10116841","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"LAND ROVER","model":"RANGE ROVER","year_from":2017,"year_to":2017,"match":"exact","vehicle_ids":["2017_land-rover_range-rover"]},{"make":"LAND ROVER","model":"RANGE ROVER SPORT","year_from":2017,"year_to":2017,"match":"exact","vehicle_ids":["2017_land-rover_range-rover-sport"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
