Bummer.
I have not seen a DIY. Maybe some one can post the TSB instructions for this? You may also be able to find a undamaged seat from a wrecked car for about the same amount as the repair? Ask the if the car needs to be "recoded" to recognize the new part. This is usually the case with the locking systems and ignition related items. The seats are heavy, sport seats weight about 60-70 pounds having a buddy to help is advisable so you do not cause any further damage.

It goes away when you clip the passenger seatbelt in.
I'm thinking about trying to look at hotwiring the seatbelt sensor so it always thinks the seat belt is clipped in. Just haven't had a chance to investigate enough yet. Wish I had a spare seat belt reciever. |

Interesting case of a sensor...and international regulations regarding seatbelts and airbags.
Here in Taiwan, my 2011 e92 does not give a damn if my passenger wears a seatbelt or not, never mind deactivating the airbag based on the weight of the front seat passenger. I suppose liability laws have a lot to do with it, but I would prefer that my car tell me that my passenger is wearing or not wearing a seatbelt. Unless I have a rather fine lady in the passenger seat wearing black...which given that the seatbelt is black to, requires a more thorough pre-drive safety inspection! But in all seriousness, I can't believe BMW is not stepping up on such an important safety issue. For those considering fixing it themselves, this is a complex system that MUST work when you really need it. I for one would only trust this with the professionals who have the tools to make sure it's going to work. I totally agree BMW should pay you for it, but if they are not, are you really comfortable increasing the risk to a loved one for $1000? I would get rid of the car or fix it properly. Actually, I would just fix it and make sure my dealer remembers this when it comes time for me to buy a new car... Last edited by Taipei-TT; 02-16-2011 at 06:38 PM.. |

I don't really have a problem with it other than the annoyin ding because the way mine failed the airbag is alway on so it's not a risk factor for my loved ones.

just to add to the thread, i was also given the cold shoulder by the dealership when i brought this recall issue up. i know my car was manufactured within those dates, and even though my VIN (according to their computers) didnt require a recall, i agree with those who stated that ALL of the cars should have this recall service available to them. it's not my fault the lights are on, or that the seatbelt chime doesnt go off anymore when the passenger forgets the seatbelt. i've never been in an accident or any type of situation that would cause this sensor to go bad. BMW needs to address this situation to benefit all their customers affected, not just the "200,000 units".
i refuse to pay $1000 for something they should be getting right the first time around. unbelievable.

If it's the same problem my E60 550i had, it was replaced by the dealer at no cost because here is a TSB for the Seat Mat Sensor. Not sure if it applies for the E9x as well. I'd look into it.

A TSB is not a recall... its just an "internal" technical bulletin advising maintenance workers on common failures, trouble shooting, & repair.
If yours is repaired gratis out of warranty and not within the recall window consider yourself lucky.

Well, this has happened to my 2008 335i now.. both Airbag and seat belt lights on... no chime though. Doesn't matter if the passenger is there or not.
I have not gone under the seat yet to check cables... I will now, but not hopeful. I think my wife was kneeling on the seat just before it happened to get a bag out of the back seat. I had the car off then... when I started it back up, the lights were on. I have emailed the dealership and have an appointment on thursday. I am 500kms OUT of warranty.... F_CK. I am going to push them to see if they want me to buy there again essentially.... I got the Dinan S2 and S3 suspension there, I have spent LOTS... lets see if they recognize that.

Most of the recalls affect 5 series since the E90 came out in late 05 as an 06 model....the recall date range is before the E90 production dates and a bit after they started production.
So there will be very few E9xs covered under this recall. I had my passenger side seat mat sensor covered under CPO....just paid the deductible. No sport seats so it wouldn't qualify for the recall at all. |

My 330i has this same issue as well. It happens more frequently when certain people sit in the seat. I get the annoying ding and my idrive tells me that there is a malfunction in the sensor. It will go away if nobody is sitting there after a day or so. With all the different ways to code these cars, it seems like somebody would be able to find a way to disable that sensor or tell the car to never disable the passenger airbag. I don't ever have children in my car or anyone else who wouldn't benefit from the airbag being on so that solution would be the best for me. I also tried contacting BMW and they told me that mine wasn't part of the recall, but they would run a diagnostic on it just to be sure.. but i'd be responsible for paying the diagnostic fee. Screw that, I'm not giving them money just to hear the same thing about it not being covered.

Sorry but that will not work unless your car is effected by the recall.

when you cleared the fault, did the seatbelt icon on the cluster and the warning on the idrive disappear? I'm also planning on clearing the fault too, but I gotta pay.

I think the BT handheld may do this too... I think the Procede does too - clear codes. Look into this - don't pay the bastards any more. My code didn't come back and check the date on my original post... it was a while ago. Also DON'T KNEEL ON OUR SEATS. This may have been a big cause.

I have had the airbag and seat belt light come on before. It usually goes away if I turn off the car and turn it back on. It happened a few months ago, then nothing for a while, then it did it this morning. Not sure what is going on. If I plug it in to a code reader, will it show anything, even if the light is off?
