Not all DI pumps may exhibit this sound. Some vehicles may have components which in combination with certain fuel temperatures and / or formulations, may result in aeration of the fuel within the body of the pump and cause this sound. This result is non-detrimental to the vehicle. Production changes have been made to eliminate the source of the sound. IMPORTANT: A \"clack\" or mechanical \"ticking\" sound also made by operation of the highpressure fuel pump is considered to be a normal operating characteristic and no attempt should be made to repair it.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2016/MC-10131643-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2016/MC-10131643-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10131643","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"SUBARU","model":"BRZ","year_from":2013,"year_to":2016,"match":"exact","vehicle_ids":["2013_subaru_brz","2014_subaru_brz","2015_subaru_brz","2016_subaru_brz"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
