*sigh* Seems like it's never more than a month or two before the car decides to take a little extra portion out of my paycheck. ![Wacko](https://5series.net/forums/images/smilies/imported/wacko.gif)
So, anyways... yes - I know about the infamous "Passenger Restraint System" malfunctions. The recall, etc. Searched around quite a lot.
This may still quite be the case for me, but I'm not fully convinced yet.
This is what has happened so far:
I got in the car this morning, burn my rear off on the black leather seats that've just been in direct sunlight for a few hours... turn the car on, and I see this pleasant message:

I hooked up my laptop, fired up INPA, and start trying to get some more details on any stored errors. It looks like the Passenger occupancy sensor is still functioning as expected.. I verified by getting up and sitting down a few times, and each time the sensors picked up a correct reading. See screenshot #1 below:

Belt buckles and all are also reporting proper readings:

I did manage to get this error code reading. If someone here knows some German, a summarized translation could be quite helpful
Otherwise I'm just going to retype it into Google Translate and go from there.

What is "Ignition Circuit 0"? Below that it says... Airbag Driver Position 1. Is that... my steering wheel's airbag? I sure freaking hope not.
I'd like to get some ideas/suggestions/etc before I start taking things apart.

Same error - or same diag information?
If you search around, there is a lot of information about the Passenger Restraint System failing. BMW even has a recall (US only) for it. However... That's for the passenger seat mat. But from what I saw on INPA, the passenger mat is still reporting just fine.
Have you pulled any diag info from INPA for your situation?
I'd like to see what other people have seen as well.

Here's the text of the screenshot of the error code readout.
Figured if anyone on Google comes across this in the future, it'll make discovery easier.
And an English translation via Google Translate:

Just check with BMW, you may be qualified for a free replacement of your passenger restraint system, my 545i was covered. There is a 10 year warranty on them.

That's what my dealer said too, but I called Transport Canada who then called BMW to clarify the situation and voila, it was replaced free and with a smile.
Not sure in the US if you have a transport safety agency who take customer complaints and works with dealerships for a solution. Basically the passenger restraint system is a major safety issue, you can't be sure if you have a passenger and god forbid you get into an accident, you are ok, but your passenger isn't. Of course if your car falls under the warranty, which mine did.
I would file a complaint and get it done. BMW acknowledged the issue and extended the warranty to 10 years, just like the HPFP on the 535's.
Good luck.

I'm still going to give them a call and have them run my VIN to see if they'll look at it. But if they want $175 for diag fees, I'll be telling them to kick some rocks and continue searching on my own.
@umichchris: I'll probably investigate more into coding the warning away once I can know with confidence what exactly is causing it. If it is legitimately a faulty airbag or similar... that's not really something you wanna bury.

Status update!
I'm putting my "solution" near the top, since you should probably try this before anything else:
While I was previously reading the codes, I tried to clear them from within the INPA screen for the specific module (Airbag ACSM, menu shown below):

When I hit clear.. It would go back, say all codes were cleared... but not really. Everything was still there, and no luck.
While poking around (and doing lots of internet searching) I went into the "Functional Jobs" menu:

From there, I was able to click the "Show EM" (EM = Error Memory) that displayed *all* of the codes stored on *all* of the car's computers. I clicked the Clear EM button, and it wiped everything. I powered off the car, turned it back on.. drove around the block back and forth... and all seems well. No codes came back, no warnings on iDrive, and no lights on the dash.
I'm had "solution" in quotes above because I'm not completely sure that this actually fixed anything. It's possible that this may have been a false positive from the seat mat (something could've been jostled, or it could've not liked being in direct sunlight for an entire morning, or whatever). But I have no way of confirming anything unless a code comes back (which I'm perfectly fine if it doesn't!). We'll see how it goes commuting back and forth to work tomorrow.
----------------------------------------------------------------------------------------------------
So, prior to all the above, I tried some other things:
While doing a lot of researching, I've found a few possibilities for this error:
In my case... before I managed to clear codes properly through INPA, I pulled the negative plug to my battery and left it for a few mins, then plugged it back in. Errors were still there. But... I did notice something about my battery. It's not OEM! At least, I really don't think it is. It's a DieHard (american-made) battery in there. I don't have much other info on it, but it hasn't given me any issues, but I can't completely discount this as not being a partial culprit to the restraint errors.
Anyways - I rambled a little bit, but I'm trying to be descriptive as possible. Perhaps it can lead someone else in the right direction.
I'll report back either tomorrow or in a few days to at least say if the error message resurfaced itself or not.

So, prior to all the above, I tried some other things:
While doing a lot of researching, I've found a few possibilities for this error:
- Passenger Seat Mat going bad - probably most common, usually resolved by BMW's recall on the mat sensor. From what I gathered online, if they say your VIN isn't in the recall list, bitch and moan, call the NHTSA and file a claim, etc until they fix you up.
- Bad Positive Battery Cable - I saw this one a few times while researching. I noticed a pattern between this and non-OEM batteries. I also found some cases of people saying this failed, and they noticed water in their trunk/battery compartment. Check for water around your battery.
- Bad module in the driver's door - for some reason, this threw this error for someone. I only saw one posting for this though.
- Snapping the ribbon cable in the steering wheel slip ring - If you turn your steering wheel far beyond what it should go, there's a chance you'll snap the ribbon cable that winds and unwinds with the wheel. This cable connects the buttons on the wheel, as well airbag. Breaking it will throw the airbag light.
In my case... before I managed to clear codes properly through INPA, I pulled the negative plug to my battery and left it for a few mins, then plugged it back in. Errors were still there. But...
