hello

 

452A/480A Particulate filter system - you need to have your particulate filter replaced.

 

4530/4521 charge air pressure control small turbo control deviation. - you also have a turbo related issue - possibly a bad sensor, turbo or leak. Further testing is required to verify this one. Or, you could start with the sensor and checking for leaks, to see if that does it, if not, escalate to the turbo.
