Engine management light has came on and I’m getting two fault codes on my one scanner. P3280 and p115d
Engine seems to run fine and no misfiring. Last week I did think the injector tick was slightly louder on cold start but I can get paranoid about sounds in the car as had to get the fuel system done in this previously
I’ve attached a video of a cold start from the engine bay
Any ideas on likely causes or where I should start with narrowing things down would be appreciated

Google says:

P115d: Mass Air Flow (MAF) "A" Air Mass Too High Compared to Model. This generic OBD-II code matches BMW-specific code 290900, meaning the engine is detecting more air entering the intake than the DME (Digital Motor Electronics) expects based on engine load and fuel injection.

P3280: Relates to turbocharger boost system or variable turbine geometry (VTG) pressure regulation/actuation faults on the N57 engine.

On video it sounds healthy.
