Add me to the list.

Airbag light came on about a month ago. :thumbsdown:

Being an ex-Alfa Romeo owner, I have chosen to ignore this light as figured it was yet another random error code that just needs clearing.

Perhaps I should start to worry about this then!

Where do people find this information?

If you read the BMW data specifically for the airbag SIS/safety system it has flow charts for exactly what will/won't happen in the event of an accident irrespective of error codes.


Obviously if the light has come on and the fault is a sensor directly related to the detection of a rapid deceleration (a crash), then maybe it'll impact airbag deployment.

However if it's just the seat sensors or related stuff, all the system will do is do a full triggering rather than a partial one based on occupancy.

The goal of many of the systems is to reduce the severity of deployments (based on deceleration/speed), or not deploy them at all if not required (ie, no one present in the seat)


Having the occupancy sensor not working, and a warning light on, simply means the airbags at the passenger side will trigger even when the seat is empty, thus saving you or the insurer £££ on replacing them after a crash.

Update...

I wasn't being silly in just ignoring the light. Turns out it was nothing more than a random error code. Will @ TWG Automotive cleared it for me, got it through its MOT and its been fine ever since.

Proper result! :D

I just managed to clear my airbag light using INPA and a cable from bcables.com :thumbsup: I went through the sub menus in the safety module section and one of them had 4 errors. God knows what it said (it's in German), but it obviously worked as the light is now off.

I just hope it stays off now!

Well worth the £26.99.

Don't be afraid. I worried about it too, but as above, I bought the cable and software from Bmcables.com and it took 10 minutes to turn it off. It hasn't been back on since :thumbsup:

My air bag light has been on for the past six months. :cry:

I brought a code reader off of eBay but no success.

Seems like I need the bcables.com item. I'm no computer wiz-kid whatsoever, so struggle with stuff like this. With the bcables & software set up, do I need anything else? I don't own a laptop, just a home PC and mobile phone.

If anybody near to me (Kingston upon Thames) could help me out I'd be more than willing to pay for your time, etc. :thumbsup:

Any comments / help much appreciated.

Cheers,
Kev.

Airbag light on - Have you been affected? (UK)

Post by rpc_25 » Mon Jun 27, 2016 5:26 pm

I bought my car at the end of March and the light came on, on the journey home. I've had it reset at an Independent garage, for it to come on the next day.
I've had an auto electric clean connections and reset, came back on. Had the airbag module fitted by auto electrician, didn't work. Had the seat out, checked battery terminals by same auto electrician. He's all but washed his hands of it. Can anyone help? I'm not for throwing hundreds of pounds at it. Takes the gloss off getting a new car, hugely.

do you know the fault code it generated? which airbag module as if it was a new one then you have to install it via BMW software (SSS v32) in the retrofit section, you need to have the old part number and the new one, that's because the units need to be coded to the car as it hold the mileage info.

If it not that then i could be the seat occupancy mat in the passenger seat, cheap fix is buy bypass plug off ebay for about £10 and code the car to switch of the seatbelt reminder chime.

Was that cleared using INPA or an independent garage?
