The P0460 error is a DTC code that appears when the engine control module identifies this problem: "Evaporative Emission Control System Leak Detected (gross leak)".
Although it is a universal OBD2 code applicable to almost all modern cars (since 1996), how to fix it depends heavily on the brand. Repairing this fault is not the same on an Audi as it is on a Honda.
If you want to clear the code and turn off the dashboard warning light on your own, you will need to use a wireless OBD2 adapter.
