2012 Volkswagen Passat codes

I had two parts for air sensor replace and the mechanic turn off the engine light. But the next day it’s back on. The first code was P2482 and the second was p2433.

DTC P2482 Is VW proprietary code.

Which means only VW knows what the code means.

DTC P2433 Indicates a problem with the secondary air injection system.
