chris_flies Sideways and Smiling  3040Rep 2,860Posts Drives: In Exuberance Join Date: Mar 2017 Location: Rosamond, CA USA iTrader: (0) Garage List2012 BMW E91 328i [0.00] | Error Code 0093C3 Last night, for some reason, my passenger window opened unbeknownst to me, and let in LOTS of rain water (it's been raining since yesterday morning). The passenger side of the dash was wet, the door card was wet, the carpet was wet (great!), the seat was wet, the floor mats were wet, and on and on and on. Anyways, I was driving to Lowe's this morning, and about 10 minutes after setting off, I get a red airbag light, and the seatbelt light comes on, but no dinging. 5 minutes later I pull into Lowe's and rip out Carly and run a diagnostic. No codes, but it also said "No ECU's Found" under the Airbag tab. Hmmm... About 15 minutes later, I come out of the store, start up the car, and immediately plug-in Carly, and run another diagnostic. This time I get 3 codes. So, I clear all codes, two of the codes disappeared, but one remained, in the Airbag tab. I got this code: 0093C3, with the description OC3 from Carly. After brief research, it seems that this shows an error in the passenger's seat occupancy mat. Can I simply dry out the sensor, and all will be fine? Or is it now shot from water damage? Any help is appreciated!  EDIT: Better question. Is the sensor separate from the bottom cushion, or is it all one unit that may need replacing? I can't find any standalone replacement sensors, and whole cushions are around $700!  __________________ 2012 BMW 328i 6-Speed Wagon | Deep Sea Blue with Grey Dakota Leather | Manual Swap, 330i Intake + Tune, 3.15 Helical LSD, Öhlins R&T (SOLD) 2009 BMW 128i 6-Speed Coupé | Monaco Blue with Black Sensatec | chris_flies' 128i thread Last edited by chris_flies; 02-11-2018 at 10:07 AM.. |

Then try clearing the code. Usually works. |

Would running the seat heaters help, or should I not do that since the electronics were clearly exposed to moisture? __________________ 2012 BMW 328i 6-Speed Wagon | Deep Sea Blue with Grey Dakota Leather | Manual Swap, 330i Intake + Tune, 3.15 Helical LSD, Öhlins R&T (SOLD) 2009 BMW 128i 6-Speed Coupé | Monaco Blue with Black Sensatec | chris_flies' 128i thread |

Esteban Major General   55559Rep 7,239Posts Drives: a slow car fast Join Date: Jun 2014 Location: SoCal iTrader: (0) | Sorry to hear that happened. It looks like you're having your share of bad luck. I would try what MMT says. It's worth a shot. Don't think I would turn on the heated seats since, as you said, that's where some of the damage occurred. |

Those thin electrical wires are probably soaked with water. |

Left it in front of a heater all day, thing was dry as a desert by the end. Put it back in the car, no dice. But, I did get a consistent signal from the airbag module, unlike before, which is progress. As for racing seats, I think I'm going to shoot for a pair of OMP First-R's, they're FIA-Approved full bucket seats that fit my dimensions with a little room for growth. I was also recommended the Macht Schnell occupancy sensor module, but I think I'll stick with an eBay emulator, which will keep the airbag active, but will clear the error. __________________ 2012 BMW 328i 6-Speed Wagon | Deep Sea Blue with Grey Dakota Leather | Manual Swap, 330i Intake + Tune, 3.15 Helical LSD, Öhlins R&T (SOLD) 2009 BMW 128i 6-Speed Coupé | Monaco Blue with Black Sensatec | chris_flies' 128i thread |

It was all going fine, actually. The fault cleared itself and everything was fine.  15 minutes into my drive, I decided to give the engine some go-juice, and as I surpassed 50, the lights came back on.  Came into a parking lot, shut it off, started it back up. Everything was fine again for about 15 seconds, and then it all went to hell again. I'll see what the story is tomorrow morning. Maybe my mistake was turning on the pass. side heated seats... Oh well. __________________ 2012 BMW 328i 6-Speed Wagon | Deep Sea Blue with Grey Dakota Leather | Manual Swap, 330i Intake + Tune, 3.15 Helical LSD, Öhlins R&T (SOLD) 2009 BMW 128i 6-Speed Coupé | Monaco Blue with Black Sensatec | chris_flies' 128i thread |

128ibro Private First Class   52Rep 128Posts Drives: 128i Convertible Join Date: Feb 2018 Location: United States iTrader: (0) | My cluster is on Christmas all year long because of this issue. My cousin left his coconut water leaking on passenger seat. Car was parked in lot for three days while we were in Vegas. I didn't bother fixing it and not sure what emulator exactly to buy. I just know there is two sensors that need to be replaced if I want to fix it. 1. The occupancy mat. 2. The tiny Position sensor it's hooked into the seat rail left side, if we're talking about passenger seat. Any suggestions what cheap emulator to make sure airbag will be on and drive without the red cluster?!? |
