Man, all this ford bashing. Jealous of that fix. My mini is/(was?) throwing insufficient boost pressure codes. Wastegate and diverter valve (as well as the turbo itself) are common culprits. To inspect the wastegate, I need to remove the exhaust and cat (that should be fun). If it needs replaced...the whole turbo needs replaced. No separate part sold. To replace the turbo, the car needs to be put in "service mode" (basically remove the front clip of the car), coolant system removed, intake removed...oh, and $2k for the new turbo. Today though I got the boost up to 17 psi and climbing (should maybe go a bit higher) before I hit triple digits and decided that was fast enough...so IDK.
