The resulting fuel system contamination can lead to costly repairs that are not covered under warranty. As an additional safeguard to help prevent a gasoline fuel pump nozzle from being used to fuel a TDI® Clean Diesel engine vehicle, dealers will install a misfueling guard in the fuel filler neck of vehicles affected by this action. Additionally, a new fuel filler neck cap will also be installed.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2013/MC-10124933-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2013/MC-10124933-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10124933","components":[{"id":"fuel-system","name":"Fuel system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"AUDI","model":"A3","year_from":2010,"year_to":2012,"match":"exact","vehicle_ids":["2010_audi_a3","2011_audi_a3","2012_audi_a3"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
