Hello everyone, I want to share some flaws that my Audi A4 2.0L 2009 presents. If someone can help me solve it, my car presents the code p0299 related to the low pressure of the turbo and the code p0420 related to the catalyst. I also have the code p0300 and p0301 and I have already replaced the spark spugs and the coils and it still keeps giving me the code

I have also replaced the turbo with a new one and it still throws the code p0299 and I delete the code with my scanner the check light turns off but the codes do not disappear and the car does not exceed 4000 RPM. I want to clarify that the car does not fail in idle and starts without problems but these codes persist how can I solve it
