Over time, this could degrade the brake booster diaphragm and cause it to rupture, affecting  power assist brake performance and potentially causing a complete loss of power assist, resulting in increased brake pedal effort. An unexpected increase in pedal effort could increase the risk of a crash causing property damage and/or personal injury the risk of a crash. Correction: Dealers will inspect the brake booster system for oil contamination and replace a vacuum line, as necessary.","consequence":null,"remedy":null,"notes":null,"mfr_campaign":"47L8","part_number":null,"units":444,"completion":null,"do_not_drive":null,"park_outside":null,"notification":"Safety Mfr","french":{"component":"Freins","notification":"Sécurité - fabricant","summary":"Sur certains véhicules munis d'un moteur TDI de 3 L, un clapet de nonretour contaminé pourrait permettre à l'huile moteur d'entrer dans le servofrein. Au fil du temps, cela pourrait causer la détérioration du diaphragme de servofrein et sa cassure, ce qui aurait une incidence sur le rendement du servofrein et pourrait entraîner une perte totale de l'assistance, ce qui augmenterait l'effort à exercer sur la pédale de frein. Une augmentation imprévue de cet effort pourrait augmenter le risque d'accident pouvant entraîner des blessures ou des dommages matériels (ou les deux). Correction : Les concessionnaires devront inspecter le système de servofrein afin de vérifier si l'huile est contaminée, ainsi que remplacer une tuyauterie à dépression, au besoin."},"vehicles":[{"year":2013,"make":"AUDI","model":"Q7","vehicle_id":"2013_audi_q7","match":"exact","built_from":null,"built_to":null}],"may_apply":true,"as_of":"2026-10-19","lookup":{"nhtsa":"https://www.nhtsa.gov/recalls","tc":"https://wwwapps.tc.gc.ca/Saf-Sec-Sur/7/VRDB-BDRV/search-recherche/menu.aspx?lang=eng","maker":null},"attribution":["Contains information licensed under the Open Government Licence – Canada."],"url":"https://open.wenmarpro.com/recalls/tc/2014366"}
