PHEV Special Requirement and Operation The PHEV fuel tanks are designed for the special requirements that arise from the hybrid operation for example operation of the vehicle alternates between the combustion engine and the electric motor. As a result excess pressure can build up due to the gasoline vapors this excess tank pressure must be dissipated before the fuel filler cap is opened. As outlined in the Refueling Procedure attachments the vehicle's operator performs a pressure equalization procedure to address the above situation. After this procedure is completed only then can the fuel filler flap (door) be opened to access and remove the fuel cap for refueling. Possible Concerns Even though the pressure equalization procedure has been performed/completed the fuel filler flap (door) still cannot be opened and/or related fuel tank readiness indicator (code) does not reset. The fuel tank pressure sensor may have failed and this could be the cause.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10169431-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10169431-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10169431","components":[{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"fuel-system","name":"Fuel system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"BMW","model":"330E","year_from":2016,"year_to":2017,"match":"exact","vehicle_ids":["2016_bmw_330e","2017_bmw_330e"]},{"make":"BMW","model":"740E","year_from":2017,"year_to":2017,"match":"exact","vehicle_ids":["2017_bmw_740e"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
