My check engine just came on today. I have 17,700 miles. Have an appointment with the dealer for next week. Car drives normal should I try to get an appointment sooner than next Friday?
***update 4/26/22
The lower radiator blinds were not working and this is why the CEL turned on.
Parts were replaced and software was updated to latest version.

No messages in iDrive.
Everything is green.

Almost at 14K miles.

Over the past two months, CEL has come on twice — right after start-up.
Check Control messages all show OK.

CEL went away after I shut off the engine, waited a few minutes, then restarted.

Will have dealer check it out at next service.

Had a similar issue (code P0456) - culprit ended up being a faulty gas cap.

Another one for the books, CL light came on. Code 190302. NVLD micro leak, replaced NVLD microswitch

Can you share more about this warranty and if there's any documentation? One of the lower grille flaps on my 330i m sport is broken. Dealer says its due to road debris, and not covered under warranty. What is measure 64841529?

I just had the exact same issue on my 21 m340 with 66.6k miles. dealer said that this is a known issue for the car. They replaced the filter for it.

Old post I know but I just got the code on my 2020 M340 with CEL. Code won't go away but CEL did surprisingly. Taking to the dealer Fridayy.Some other codes were present as well.

The permanent error is the 190302

Edit: Surprisingly they all went away even the 190302. If everything is good after tomorrow I guess I'll have cancel my trip to the dealer.
