I've been running JB4 and less ********* for quite some time now on my '09 135i with no issues.
I just got finished walnut blasting and installing:
VRSF 7" FMIC
silicone inlets
charge pipe w/ Tial BOV
Stage 2 Fuel-It LPFP
NGK 95770 gapped at 0.022"
I then updated to the latest JB4 firmware, filled up with 8 gallons E85/4 gallons 93 and flashed the latest E85 backend flash.
After that the car is running great (except for major clutch slipping in 4th+ gears from all the new torque ) but now I keep throwing a SES light for "******* ********* detected".
I thought maybe I just had to enable auto clear again via the steering wheel control (menu 1 option 3), but I've done this a couple times now and the code keeps coming back...
