This allows either too much oil to enter or not enough oil to exit the turbocharger and will overwhelm the seal. Action required: DO NOT replace the turbocharger(s). Remove the pressure pipes from the turbochargers to determine which side is stuck open. Replace that line.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10125195-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10125195-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10125195","components":[{"id":"engine","name":"Engine","parent":null},{"id":"turbocharger","name":"Turbocharger or supercharger","parent":"engine"}],"codes":[],"topics":[],"vehicles":[{"make":"PORSCHE","model":"911","year_from":2016,"year_to":2017,"match":"exact","vehicle_ids":["2016_porsche_911","2017_porsche_911"]},{"make":"PORSCHE","model":"911 TURBO","year_from":2016,"year_to":2017,"match":"base","vehicle_ids":["2016_porsche_911","2017_porsche_911"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
