If a diesel engine vehicle is filled and operated with gasoline, internal engine damage, fuel delivery and emission control system failures will occur. Only fuel nozzles with the recommended \"specified\" diameter for diesel engine passenger vehicles can be inserted into the filler neck. Most fuel stations have their diesel fuel pumps fitted with this recommended diameter fuel nozzle. However, if the vehicle's filler-neck misfueling protection system has been disabled, or the incorrect diameter fuel nozzle has been installed on the diesel fuel pump, the vehicle's diesel fuel system can be contaminated by filling the diesel engine vehicle with gasoline. If the diesel fuel system has been contaminated with gasoline, follow the repair guidelines below:","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2014/MC-10149359-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2014/MC-10149359-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10149359","components":[{"id":"fuel-system","name":"Fuel system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"BMW","model":"K SERIES","year_from":null,"year_to":null,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
