Hi all,

First post here and hoping for some help sorting out a P0456 small leak in the evap system on my 2013 X3 with 48,000 miles.

Seem to be going down the rabbit hole with this one. Here's what I've already replaced/ done:

- Smoke test performed, no visual leaks found
- Fuel cap replaced
- NVLD pressure switch/ module replaced
- Purge valve and associated hoses replaced
- Charcoal canister/ filter replaced

Since all of this work performed I've driven the X3 nearly 500 miles and retrieve a pending and permanent stored P0456 code with no CEL.

Open to any and all advice or help, thank you!
