This thread was tremendously helpful, thank you
rocket_science !
I got a 2008 E90 335i "track" sedan with Racetech buckets and 6 point harness. I kept oem front seat belts and tensioners for the street. Front tensioner cable is plugged to the socket under the seat. Rear seat tensioners removed.
My experience
- I did not code VO (+RECA), didn't want to re-code all the modules
- I only succeeded if I coded against FRM ECU (not CAS), writing to CAS didn't error, but didn't take any effect - stumbled me for a while
- I changed the following to nicht_aktiv via NCS Expert/NCS Dummy following instructions from
LMB335IS , in order they appear in FSW_PSW.TRC:
CC_GURTWARNUNG_1
GURTSTRAFFER_FONDLINKS_1
GURTSTRAFFER_FONDRECHTS_1
OC3_1
SBR_FAHRER_1
SIDEBAG_LINKS_1
SIDEBAG_RECHTS_1
GK/OC3/POL
AACN_1
O_GW_F_1
SBR_BEIFAHRER_2_CD
This might be too much, but I tried to match parameters in my car with original post and additionally disable rear tensioners. No airbag errors/warnings on the dash at the moment.
Below is the whole NCS Dummy export from airbag module (ABG) after the changes were applied.
