Cause The vibrating air column of the purge flow volume triggers the fill limit vent valve (FLVV) to open and close repeatedly when the fuel tank is full. Remedy By reducing the fuel quantity by around 5 liters, the noise can no longer be heard. In isolated cases, the noise can also be amplified by a fuel tank installed under stress and therefore lines adjacent to the body-in-white (above the fuel tank). In this case, the installation position of the fuel tank and the contact surfaces to the body-in-white must be checked. To do so, loosen the fuel tank and refasten it. Please do not replace component parts such as the fuel tank, activated charcoal canister, purge valve or delivery module, as this does not provide a remedy. If a similar noise can be heard with a tank fill level of, for example, 3/4 or 1/4 and not with a full tank (1/1), there is a different issue.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11023046-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11023046-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11023046","components":[{"id":"fuel-system","name":"Fuel system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MERCEDES-BENZ","model":"AMG GLE53","year_from":2021,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLE53 4MATIC+","year_from":2023,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLE53 4MATIC+ COUPE","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLE63 S","year_from":2021,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLE63 S 4MATIC+","year_from":2023,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLE63 S 4MATIC+ COUPE","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLS63","year_from":2020,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLS63 4MATIC+","year_from":2023,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"E 350","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"E 350 4MATIC","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"E 450 4MATIC","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"E 450 4MATIC ALL-TERRAIN","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLE 350","year_from":2020,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLE 350 4MATIC","year_from":2024,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLE 450 4MATIC","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLE 450 4MATIC COUPE","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLS 450 4MATIC","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-MAYBACH","model":"GLS 600 4MATIC","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
