Thx for the share. Think i’ll do let it idle for a while b4 shutting off. YOu never know who’s really writing up on these Manuals.
What are you trying to say with the photo you shared ?
I’ve changed a number of water cooled turbochargers under warranty that failed due to coked motor oil so my advice is allow it to idle for a short time before shutoff; especially if the car has been driven a bit hard.
