Airbag and Seetbelt light on after interior car detail

vrejii · 07-21-2012, 10:31 PM

hey guys I took my car( 08 335i coupe) in for a car wash and detail today with only a tire pressure light on due to my tires and when i got my car back 30 mins later I had a airbag and seatbelt light on( even when im wearing my seatbelt) I addressed it to the manager of the car wash and he was a complete idiot that barley spoke english and kept saying it is a mechanical problem so I gave up trying to explain it to him. anyways I dont know what they did to cause this but I'm thinking the seat belt buckle mustve shorted out and caused it but im not sure.

have any of you experienced anything like this ?

Also cant seem to find a place to buy a seat belt buckle.. anyone happen to know the part number?

Any help is deeply appreciated.

Verify the connector under the seats first and get the error code removed. You can do it by coding with INPA, BT cable or by the dealer.

I have the same thing. I have istalled INPA and tried clearing but no luck. I do not want to code out the errors I want to fix them.

antzcrashing · 12-17-2012, 06:55 PM

Please confirm, is this the error you have?

james008 · 12-17-2012, 09:30 PM

Yes, non-stop. I clear them, or at least try to and they come back within seconds. And I can't read the specific module to see when the error happened or any details that INPA usually shows.

There air bag wiring under driver and passenger seat. Maybe it sort or unhook when you have your car clean. Guy replace my under seat subwoofer told me that. Hope this any help.

Does anyone know the BMW PN for the mat sensor? Is there a DIY on replacing it?

antzcrashing · 12-18-2012, 08:23 PM

Found this thread about the issue, apparently many e90'ers having the issue and BMW denying recall on it

He could of ruined the connector . You might want to reseat it or take
it off and have a look at the pins at the connector. The safe way to do it
is disconnect the battery first. If her really wanted to clean there he could have just leaned the seat back on the mounts without disconnecting anything.
Cars that fall withing a certain date range for the sensor in the passanger seat get it replaced for free in the first 10 years of service. You have to look up the recall to find out if you qualify.

Okay this ebay link near the bottom there is a screen shot of INPA. How do I get to that screen? Again I have INPA working but cannot find that screen to check anything related to the airbags or seat sensors.

james008 · 12-21-2012, 02:37 PM

I sorted my problems out a little. I updated to a new version of INPA and updated to daten v42 files and am able to read airbag. Found out active headrests on both passanger and driver side are what is throwing my codes. I did an interior swap with an 08M3 that does not have active headrests so I will need to code them out and then clear. That should solve my problem.
