what causes these codes to appear

so I got three codes while driving and getting on the throttle in 4th gear and I got a P003A boost control turbocharger boost control module position exceeded learning limit. P00AF turbo charger boost control module performance. and the last one is a weird one to me U010CDTCdescription not found

You have a bad turbo actuator. As evident by the U code.

There are 2 other current threads on this right now.

Here's one. I have a post about how to confirm the turbo actuator failure.

Likely bad actuator as mentioned and agreed with above. Slight chance it could be a low voltage thing- I had something similar codes to those and my batteries needed replacing. I don’t remember if it was 4 but I had multiple codes. Once I replaced the batteries I had no more turbo codes. Keep us posted
