I just bench unlocked my 2020 M340 with the MHD Unlocker; no tune yet. I didn't have the DME plugs back in tightly, so it threw a ton of faults, wouldn't start, etc. Once I went back over carefully and made sure they were all tight, it started back up and ran just fine.

MHD code scanner is showing no codes now. Bimmerlink shows one permanent error, D3569B (Message (diagnosis OBD engine, ID: DIAG_OBD_ENG) is missing). Not sure why MHD isn't throwing this code if it's actually a problem, and in the past Bimmerlink has shown more codes that were either shadow codes or informational, but I've never had a permanent error.

My understanding is that you can't clear permanent errors via Bimmerlink and the car has to clear it on its own. I can't find much on the code itself, though it is on bmwfault.codes. Should I just keep driving it and monitor? I assume if a DME plug was still loose, it wouldn't drive or I'd get a ton more codes.
