Code 190302

[sa90h]

I’m getting a CEL from a code. The code is 190302 “tank-venting and purge air Feinstleck: leakage greater than 0,5 mm”. Anyone know what this code can be? Cleared it a couple times already but it keeps coming back. The seal on my gas cap seems to be fine as well.

Also, I’m stock downpipe on 91.

Check your gas cap and gas cap seal or a fuel leak

Having this issue since last summer.
Changed:
Purge valve
Gas carp

Still have the code. But no more hard start (cranking longer than usual). Still have idle variation after cold start.

Took it to a shop for smoke test. No leak found.

I pretty much gave up now. I dont have CEL anymore but the code are there when i scan.

Did you figure out what’s going wrong? I’m having the same issue. Thanks.
