Hello,
F31 340ix: PTF Flex kit + TU Pump
I'm running BM3 stage 1 multimap for nearly 2 years, on E60 to E85.

Outside of cold start issues (the more E, the less it starts, can take up to 5 secondes) and some multimap boost management (fixed), the car is running great.

Today I got a CEL on the dash, no drivetrain error/fault in idrive.
laptop plugged, fault in BM3 says :
code 118001, mixture too lean.

Car is fine, nothing has been noticed, I saw the CEL during the drive when looking randomly on the dash.

I took some logs to check

From my perspective, I'm seeing nothing bad, maybe a very slight variation on the HPFP, but nothing crazy...
CEL didn't come back as of now.

Any idea ?

thank you !
