Default N55 JB4 Wastegate settings - 07-14-2018, 05:47 AM

My car is not working correct because my wastegate setting are off
Should I reset to the default settings of wastegate position to 60 and if so and my cars FF/ wastegate adaptation does not go to 100 is something wrong with the solenoid or something else? Thanks

First step in any diagnostic is to attach a JB4 log of whatever problem you are having is.

Nothing you said in your post indicates any issue. DWP=60 is default, FF learns as needed to keep boost on target.
