Can you post a video after fix just for comparison?
I got his sound today. After i switched off the engine for 5 min and started up again it was gone. I'll have to check it at dealer. omgdigitalsakurauk wrote: ↑Fri May 18, 2018 8:18 pmdevonaygo wrote: ↑Fri May 18, 2018 7:25 pmThere is a Technical Service bulletin from Toyota that may apply:
