Until recently the failure of the exhaust muffler valve actuator has required the exhaust muffler and valve to be renewed as a complete assembly. The exhaust muffler valve actuator is now available as a separate replacement part. The advantages of not having to replace the combined assembly are for a faulty actuator are: - Less labour-intensive procedure to replace. - More practical to keep an exhaust muffler valve actuator as a parts stock item. If an exhaust muffler valve actuator is diagnosed as faulty then please determine if the exhaust flow valve mechanism in the rear silencer is operating and moving correctly*, if it is then please fit a new valve actuator instead of a complete muffler assembly. *Actuator replacement is only suitable if the exhaust flow valve mechanism in the rear silencer is operating and moving correctly. If the exhaust flow valve is not operating or seized, then the exhaust silencer or actuator assembly should be replaced.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11031269-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11031269-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11031269","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"LOTUS","model":"EMIRA","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"LOTUS","model":"EMIRA","year_from":2024,"year_to":2026,"match":"exact","vehicle_ids":["2024_lotus_emira","2025_lotus_emira","2026_lotus_emira"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
