Hello,
If I could jump in here for a second, there is no Direct Trouble Code (DTC) P, B, C, or U (Power-train, Body, Chassis, Network) 0456 in the DTC list for your vehicle. Could you please double check the DTC number again and get to us with what you are able to find out. To reiterate BMDOUBLES answer, I would check to make sure the air filter housing is snaps shut and ensure that the proper air filter was used and is seated in the housing correctly. Please get back to us with what you are able to figure out.
Thanks,
Alex
