Terrible AIRBAG issue

Futie · 12-02-2009, 10:01 AM

Since 3 months I have a check lamp ON for AIRBAG and SEATBELT on my E90. After I Dynamat-ed my doors I saw that the 2 front crash (DOORS) sensors as well as the two under the headlights were misteriously UNPLUGGED. Of course I plugged them and DING DING---AIRBAG! I tried to clear the fault but not result-- comes again.
Last week I was hunting for vibrations and squeaks and suddenly!
The brownwhite wire is MISTERIOUSLY unplugged?!(Attached Photos)
Can you help me reading the meaning of this wire and if I plug it in again what could happen?

I bought my car second hand, there is no more warranty and I don't want to go to the dealer because it will cost me a fortune and probably they will tell me to change the car!

Please take a look and if you have some suggestions,for example WDS BMW which I can't read, let me know.
THANK YOU

***This is the AIRBAG Module which is placed under the Armrest/Center console - just below the rear vents***

If you can find a diagram for the wiring, I could read it for you. I just can't seem to find the wiring diagram.

I have just read the diagram but I am not 100% sure if my AIRBAG Module is MRS(Multiple Restraint System). But on the picture with the module we can clearly see "MRSZ5" which tells me I have MRS.
Could you help me with this or I should visit the dealer for a quick question
Thanks
