I have 2013 335i with 53K with check engine light on with lean codes. This is my first turbo car and I am having a hell of a time fixing these codes. Here is what i've tried so far. Hoping someone can help me out.

Walnut blasting
Smoke test
Replaced all spark plugs
Cleaned sensor on the intake pipe (it's only a few months old)

These are the codes I pulled with ISTAD

This is probably a basic question: these codes keep coming up even after you've cleared out the faults? Any mods?

Yes! The car is stock and they come back a few minutes after I clear them.

Bueller?

If it's un-modded, I'd take it to a dealer and ask them for a good will repair. It's quite new, and only 3K miles out of warranty, after all.
