P0442 help!

eli371 · 10-10-2017, 12:59 PM

Hey all,
I have a 2010 sdrive35i and recently i got a couple warnings to tighten/close my gas cap and eventually getting a P0442 code (small evap leak).

Naturally the first step was to replace the gas cap, cleared the code, shortly after, it threw the CEL after the tigthen gas cap warning again.

Next step was to replace the solenoid near the intake, the dealer was convinced this was the issue. Had that done, cleared the code and shortly after getting the tighten gas cap warning again, the CEL came back on, this time, i still kept getting the tighten gas cap warning after it threw the CEL.

Any suggestions on where to look next before i spend an arm and a leg to have them "diagnose" this for me.
thanks for your time/help.
