Air Bag - Light

I have a Faulty Sensor Light Air Bag Light on Dash -which is annoying


I see that they sell a Passenger Occupancy Seat Sensor Bypass unit - Emulator



These may be a Dumb Questions - are these Bad ? Are they just fooling the computer bypassing the signal ? Will the Air Bags still work ??

hmmmmmmm now im think of canceling my order and going with this emulator they have on ebay but will it also work for the driver side.

Since our's isnt passenger .... and im guessing the bypass is specifically for the passenger.

Can someone give us some advise before BMW goes ahead and charges me my arms and legs to fix.

Its the passenger seat occupancy sensor. Good news the sensor is only around 70$ online. Bad news is you can diy but the seat must come out held in by 4 bolts, and you must remove the lower cushion.
There are about 30 upholstery "hog" clips holding the leather to the seat. The sensor is under the leather. I have the same problem for my passenger seat except I have had a rip in the seat ever since I bought the car.

When I got my battery registered at BMW, the tech cleared the code and it has not come back on since..... Not sure if he permanently cleared it or what???

I'd go with the emulator. Or if you want your car perfect go and order the sensor and DIY. Not sure the difference but I know the airbags gonna always go off even if no ones in the seat.
Your driver seat has a bad occupancy sensor.

edit: the emulator is what I would do, but I have to replace the leather so I'm going to replace the sensor also.

You do know that the bypass module your
Trying to buy , will keep the airbag from
going off right ???


Why not fix it the right way & buy the part
Then DIY it ???

Email this company with the last seven of your vin and they will tell you which one you need. your airbag will still work when the bypass is installed.

I'm sorry but you are incorrect , The AirBag for that seat
will not work with the bypass installed . This is a proven
fact , As it happened to a member from the site was in
an accident & his airbag did not deploy for the seat that
had the bypass on it ...

My module will not only remove the airbag light (like some other sellers on eBay) but will also ensure that the on-board computer recognizes that a passenger is present in the passenger seat and seat is OCCUPIED. So with my module installed, ALL AIRBAGS WILL WORK PROPERLY AND DEPLOY IN THE EVENT OF AN ACCIDENT. Please see the BMW Diagnostic Software ISPA screenshot below when I connected to my 3 series E46 car.

This may not work for you being that its your drivers side.

I really don't think You can compare a 3 series E46 to a 7 series E65 or E66 .
But hey what do I know ???

Well I guess I do know that the Bypass did not deploy the passenger airbag
in a members 745LI , when him & his Wife were hit on the passenger side
of there car , But all other airbags worked .

HHHMMM I guess I'm wrong & your right ...


EDIT = Revise my statement
I don't know what Bypass They used .
Where they bought there Bypass .
Or if it was the 1 you provide .
All I know is the Bypass they used prevented the
airbag from working ...

Hey Paper i appreciate you taking the time and advising us on the bypass.

Paper it's not the question of money really. Its about the fundamentals of a stupid BMW occupancy sensor who's sole functionality is to provide a binary 1 for get occupied and a 0 for no passenger cost 1160 at the bmw dealer.

I find that absurd, at the same time BMW Canada will not respect the recall that BMW USA is providing for the issue, which angers me.

Paper if you know of any DIY instruction so i could actually buy the sensor and install it myself i really would but i haven't been able to find any instruction nor have i been able to find the sensor online.
for my BMW 750LI 06

My 06 is the 2 wire even though all the companies I asked said 3 wire. I couldn't get the dealer to fix the drivers side under the recall. I would have no problem going DIY to make it perfect, but I don't see any reason not to use an emulator on the drivers side.

All the emulator does is shows resistance equal to an occupied seat. I really doubt that would lead to not deploying the airbags. You can see that it shows the seat is occupied in inpa with the emulator. I could see if that guy did the bypass through coding and it didn't deploy.
