Race Seat Coding - Solution
I know many of you run race seats and are using the OC3 emulator modules to remove the error codes generated by the removal of the factory seats (airbag and seatbelt/restraint errors). While these modules are an "easy" option, they are also incredibly expensive. Especially when you consider it can be done for free through coding.
The problem it there have been several posts about coding for race seats but these threads are all missing items to watch out for. As I am in the middle of installing some Racetech seats myself, I thought I would take the time to test all typical error causing settings and provide you with what I believe to be the full list of steps to ensure your E9x M3 is coded to remove the factory seats so you do not receive any lingering codes. Note: I am not going to walk you through the coding process, just the items to update. If you need help learning to code, see here: http://www.e90post.com/forums/showthread.php?t=451145 I used NCS to do the following: 1. Add +RECA to the car's VO -Recaro Seats 2. Ensure all the following are set to nicht_aktiv in ABG module: SIDEBAG_LINKS_1 -Side Airbag (left)Clear all error codes codes with ISTA/P or software of your choice That's it! So long as you are familiar with coding, this should not take longer than 10 minutes. Last edited by rocket_science; 12-13-2016 at 10:07 AM.. |

Hi - many thanks for the informative thread.
My German is limited, I understand links and recht but do you know what they all the items mean? What are you turning off? Cheers Anthony |

Thanks very much. That is very helpful. I've not seen the Recaro seat option added to the VO before.
I understand what most of the items you list should be set to 'not-active'. The side airbags, are these the airbags in the seats or door frame? If they are the seat airbags, makes sense to use 'not-active' as airbags are not present in motorsport seats. Also do you know what happens to the passenger airbag above the glove box? Will that still fire at all times in a suitably fierce accident or is the seat occupancy effectively telling the car that it is unoccupied? |

If you are going through the process of removing the factory seats, one can only assume the move to race seats and obviously harnesses (and hans device too). So ultimately, airbag pop or not, it should not be of too much concern. At least that's my opinion Last edited by rocket_science; 12-20-2016 at 08:11 PM.. |

Thanks to the OP for putting all this in a single post as it takes some fishing to find all the info. |

Old post I know but hopefully someone can help. I have followed instructions to the letter and done all the coding changes in the ABG module and cleared codes but still getting codes (less than before) and the annoying seat restraint malfunction on the dash. However the only thing I haven't done is the +RECA to the VO, I can't seem to work out how to do this. I get to the part of the $ values and get quite confused and don't want to do anything that messes my car up. Can someone shed some light please? codes I'm getting below: S0337 no communication with driver seat module S0338 no communication with passenger seat module 0093C1 MRS: communication fault, seat occupancy detector passenger 00CF41 DKG: signal from drivers seat switch buckle |

if you can already disable those features then +RECA won't help you much |

Because putting things in VO form will change values in other supporting ECU'a as well. Not only does ABG module need changing but so does Kombi, CIC, FRM..... Vo coding will set this up crudely and you can change specifics like OP posted. Other wise you may need to add lines as well as nicht_active or a value.
