I have the same identical issue as experienced in these models but for some reason my vehicle VIN is not on the list. The problem details are below. 2007-2012 (gasoline models) and certain 2013-2015/2017 (gasoline models) Audi Q7s are covered by factory recalls for a fuel pump flange that can develop fine cracks/fissures, allowing fuel leaks and a strong fuel smell (often noticed toward the rear).

plastic fuel tank itself in most cases, but cracking of the fuel pump flange (filter housing/part of the fuel tank assembly) supplied by Continental. Leaking fuel near an ignition source raises fire risk. Only gasoline engines are affected (not TDI diesels). Key recalls * NHTSA 16V660000 (Audi code 20W9) - 2007-2012 Audi Q7 (gasoline). Dealers inspected the flange, replaced cracked ones, and applied a protective butyl rubber band/film as an interim measure when parts were limited. * NHTSA 18V818000 (Audi code 20BJ) - Follow-up for a subset of the above 2007-2012 vehicles that only received the interim butyl tape repair. The tape could be insufficient, so the flange is replaced and new protective tape applied. * NHTSA 17V298000 (Audi code 20Z8) - Expansion covering certain 2013-2017 Audi Q5 and Q7 (gasoline). Summaries often list 2013-2017 Q7; some official notices and details focus on 2013-2015 Q7 (still first-generation). Flanges are inspected/replaced if cracked, or protective film is applied.
