serge73 Private  12Rep 76Posts Drives: BMW x3 2020 M40i Join Date: Mar 2009 Location: Houston, TX iTrader: (1) | e90 code 93C3 randomly when somebody sites on the passenger seat, the red airbag light turns on and remains on. I had the shop read the codes today and 93C3 popped (seat occupancy detector). Anybody know what this is and if the fix is a DIY?, shop didnt tell me a lot other than check with BMW if this was a recall as the sensor might be faulty..... |

| serge73 Private 12Rep 76Posts Drives: BMW x3 2020 M40i Join Date: Mar 2009 Location: Houston, TX iTrader: (1) | Seems nobody has had this issue in the past?, I checked with my local independent shop and they said this was a safety issue (obviously) but recommended I go to the dealership for this type of work. I am afraid to step in there and get a HIGH invoice for some monster safety repair..... any other ideas out there?, or suggestions of where I can get some advice? |

gmfm New Member   1Rep 25Posts Drives: 07 E90 335i Join Date: Oct 2010 Location: Irvine, CA iTrader: (0) | I just got this code (93C3) starting last week. I cleared it and it came back as soon as I had a front passenger again. I have a service appointment scheduled for tomorrow (I have CPO warranty) and I'll post back here with the amount they bill to warranty if I can remember to catch a glimpse of the warranty invoice. |

| gmfm New Member 1Rep 25Posts Drives: 07 E90 335i Join Date: Oct 2010 Location: Irvine, CA iTrader: (0) | Funny thing too... Since they recoded the entire vehicle I lost all my coded options, including my MoBridge iPod adapter (CDC). I spent about 2 hours in the car tonight re-learning NCS. |

| serge73 Private 12Rep 76Posts Drives: BMW x3 2020 M40i Join Date: Mar 2009 Location: Houston, TX iTrader: (1) | yep, mine ended up being the mat sensor. but it seems that in my year/month production this was not a BMW recall so it was not covered (out of 4 year/50K warranty too).... the service agent said she worked with me and that they would split the bill 3 ways (bmw, dealership, myself), so my out of pocket ended up being $250. More than I wanted but less than what it could have been, i guess..... |

Have the dealer address it if you're under warranty or else it's expensive out of warranty. My previous MINI had the issue and it was 1100 to fix (Canadian price though). The seat mats are defective in MINI Coopers, 3 series and 5 series also. __________________ '09 LCI 335i E90 in BSM over Oyster Dakota Leather, Manual, Sport, Navigation, Individual Audiophile, Executive, Active Steering, JB4 + MHD BEF, 335is Exhaust w/AWE Tuning Tips, AFE DCI, Euro Tails/Fog Light Switch, various painted and other OEM + mods, 19" M5 reps summer '13 MINI Cooper S Paceman JCW R61in Light White & Black Roof/Mirror Caps/Sport Stripes, Loaded + Rare |

| serge73 Private 12Rep 76Posts Drives: BMW x3 2020 M40i Join Date: Mar 2009 Location: Houston, TX iTrader: (1) | true, mine was intermittent for a few months so I kept ignoring it until it started happening almost everytime somebody sat in the passenger seat. Finally had it looked at and as described above, Mat sensor replacement. |

| JHZR2 Major 80Rep 1,001Posts Drives: 91 E30, 11 135i cv Join Date: Mar 2009 Location: New Jersey iTrader: (0) | Just happened on my 135i (e88) - 93C3 error. Haven't had a front seat passenger in nearly two years now, since we had a child that requires an infant seat. Just a bigger kid in back seat. Front passenger seat just gets tilted for entry/exit. Literally drove for an errand and it was fine going to the location, when starting up to go home this popped up. Out of nowhere. Very frustrating. Last edited by JHZR2; 07-06-2018 at 10:05 AM.. |
