Do I have any other options other than removing the airbag module and sending it to a reprogrammed? Could this procedure be done myself??

I bought a salvage 2008 E90 328i (VIN: WBAVC53557FZ70481) and it is just about all put back together. I just have to deal with the several dash lights tho.

The car starts and idles well, but the Airbag module is storing data that needs to be cleared.

I am going to purchase the BimmerGeeks cable and hopefully that will get me to the finish line.

You can reset a and program a lot of stuff with
the Inpa Suite and Ista D.
Ista D is what the BMW dealerships used for years.

I took a look and ISTA is def awesome. But I didn't see anywhere that it can reset a Airbag module after a crash and wipe the crash data.

Or maybe I missed that..

I purchased this BMW from an auction after the insurance company wrote it off. But the Airbag module needs a reset and to clear the crash data. Not sure of the legality of doing this, but thought that this is the right place to at least ask.

You can clear crash data on E90 with any diagnostic equipment, 2 times.
3rd time will need to remove airbag controller and read/write eeprom with programmer.

In a similar situation and wondering if you figured it out? I have it all back together and my Foxwell NT510 cleared all the codes except the stored airbag control module data...Don't want to take it out if I don't have to.

Are you sure you don't have a blown or defective BST.
BST has to be replaced if it goes off and also is one of the
reasons you cannot reset the Airbag error if it is defective
or has been triggered.

Its easy to find stuff in Ista D just by reading the car then
putting relevant stuff in the search window like airbag for instance.

Hi,
On E83 (old X3) you can just use any scan tool to reset faults after you have put in the new airbags.

On my E92 (year 2012) I took out the module and had it reset by a local workshop that specialises in module cloning, instrument clusters and crash data removal. They charged me approx. $100 for their work, and they told me to NOT power it up until all new airbags had been installed and connected, as this type was tricky to clear faults on. It became perfect, the module had no faults when I connected all the airbags before powering up the car.
(I didn't try if you can clear faults myself, so can't tell you if its correct that you have 2 allowed clears yourself).
Cheers,

I can’t seem to cear any codes using ISTA D or INPA
I choose read EM then I choose clear codes. It says it successfully cleared the codes but when I go back to read them they are back

What codes are they?

In a similar situation and stumbled upon this thread, happy to see it's still active.

2010 335i xDrive coupe front left collision. Steering wheel, both curtains, and drivers seat airbags deployed.

Tore apart the BST, reconnected the power cable, cut the connector at the bst and jumping it with a 2 ohm resistor (as seen in many other threads)

Car gets power, but won't turn over at all and displays the passenger restraint fault (along with several others from the collision such as 4x4, headlights, traction control etc).

Can read all of the airbag codes with a OBD tool Creator C110.

If the codes are "cleared" with the tool, will it allow the car to start?

After reading through the thread, I am assuming the airbag module needs to be flashed somehow? What software is required do clear the crash data?

Thanks,
Ben

The BST fires during a severe accident.

Yeah I realize that, I tore apart the BST and forced the large gauge wire back in to the socket.

I absent-minded-ly haven’t tried jumping from the front terminal yet. So if that starts it, something is not correct with the BST or the way the battery is hooked up.

I was under the impression that the car will not start with crash data, but after more reading it sounds like it should still start up after the bst is replaced or bypassed.

If you believe some of the stuff on google it would seem
you would need to send the Air Bag module to clear the
data . I don't know how BMW does it , looks like there should
be away to do it from ista or Inpa but I am not sure.
You should be able to at least check to see what it thinks of
the state of the airbags other safety devices through the
mentioned programs.

Without Ista or Inpa or one of the BMW compatible scanners
you are pretty hobbled.

Any MRS resets on your scanner.

Have you checked for fuel pressure and spark?

Whats the the voltage read at critical points?

If you don't list the codes how do you expect to get a good
response?

[bwats23]

Listen I’m not saying you gave me a bad response but I’d expect that you read my problem description which said that I have tried to bypass the BST.

No reason to check for fuel or spark (yet) if the starter is not engaging.

I’m betting it will fire right up when I jump it from the front terminal, and that the problem is in fact somewhere in the battery loop, and perhaps my bst fix is not functioning correctly.

Sorry if you misinterpreted my question and thanks for the input, I’ll update after I attempt jumping from the front.

Hi,
If you push the BST back together you will have power back to the vehicle.
After you clear all faults with a code reader such as Creator C110 (mine is C310), or use ProTool phone app or NCS tools, I believe you will be allowed to re-start your engine.

I have tried this on an E83 (X3 diesel), it allowed me to re-start the engine on that one. But I haven't physically tried this on E90.

For my E90, I replaced the BST, and I took the airbag module down to my local instrument specialist for repairs. It was all good. Didn't cost much, and it was fault free like new when I installed it back and applied power to the vehicle.
This is the shop I went to. (in Australia) They do mail order service also, https://www.speedlineinstruments.com...module-repairs
You may find similar specialists within your country as well, otherwise contact them for shipping quote and prices.

Hey guys,

It was the clutch safety. The front left impact caused it to come off. Reattached it and it fired right up.

Thanks for everyone’s input.

For those trying to debug a similar situation, you can find this in the CAS portion of the data stream with a obd tool.

Or in some situations, there is a dash light which shows a foot and a pedal, signaling to press the clutch. But with many attempts to start it, I only saw this pop up once, which led me to investigate.
