Good evening, wondering if anyone can help with this problem. I have C4 1.6 hdi '07 that I purchased about a week ago with about 90k miles. After driving for about 300 miles I get the anti pollution fault on the display, but the car is actually running fine, no limp mode or anything

I've connected my ODB scanner and I get " P0100 Powertrain (Mass or volume air flow circuit" and " P0234 (Turbo/Supercharger overboost condition).

Anyone know what could be causing this?
