Volume of audio system (when set to near maximum) is reduced when Auto Start-Stop (MSA) stop occurs and is not restored upon automatic engine restart. This is normal system behavior - serves to protect the head unit, battery drain and avoidance of incremental leaps in the loudness. The loudness is reduced to 2/3 of maximum and is not restored. Note: Air conditioning output is also reduced upon MSA stop and is not restored for similar reasons.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2016/MC-10146929-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2016/MC-10146929-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10146929","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MINI","model":"COOPER","year_from":2014,"year_to":2015,"match":null,"vehicle_ids":[]},{"make":"MINI","model":"COOPER","year_from":2017,"year_to":2017,"match":null,"vehicle_ids":[]},{"make":"MINI","model":"COOPER CONVERTIBLE","year_from":2016,"year_to":2016,"match":"exact","vehicle_ids":["2016_mini_cooper-convertible"]},{"make":"MINI","model":"COOPER S","year_from":2014,"year_to":2016,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
