Fault Code P1417 on Z4M

[motco]

My son has a Z4M Coupe and it's been behaving erratically on the odd occasion. The OBD2 fault codes are NA and P1417. Assuming the first one is not applicable, does anyone know what the other one might be please?

The code means "Port Air Relief Circuit Malfunction" - can't help with what that means though.

Have you tried resetting it to see if it comes back, as they do sometimes log phantom codes.

Thanks for your help. It has cleared after a couple of re-starts, but it's a bit concerning that it happened in the first place. Watch and wait should be the motto, I guess.
