Pass. Restraint system

For the last week my Pass. Restraint system turns on an off I was wondering if there is a way to reset it to keep it off.

I would have your battery checked. A fully charged battery with a weak cell, will cause this to happen. When I had this problem, I could not believe how it was caused by a weak battery. When I installed my new battery, the fault would not clear until I charged the new battery for 12 hours. I did all the work myself, so I know how confusing this could be!

Check to see how old your battery is, before shelling out around 1k in repairs!

I had the batt changed about 2 years ago. I am going to give it a full charge and see if that will do the trick. Thanks for the info HerbP

I am getting the same fault, BMW is saying that it is the "ECU, airbag with gat" and cost $1016...I am not sure what means but I know its definitely attached to the battery because just this past week I had to have almost every component in the trunk replaced because of flooding..I didn't get that replaced because I have to go into another dealership Friday for DINAN and Oil change and was trying to combine labor. If it is the battery let me know, my battery seems to be fine but during diagnostics at the dealership a "Battery exhausted" fault came up but the service tech said all was fine.

If DIS said the battery is exhausted, it most likely is. BMW only gives 2 years warranty on a battery. You can buy one much cheaper at any auto parts store these days, with 6 year warranty. I got mine for 120.00 at O'reilly's, then ran my own registration. These cars are battery hogs!

Thank you for the info Herbp, I may just go buy a battery tomorrow and let this third party shop register it since they will be doing some Idrive coding before I go to BMW Friday. BTW has anyone ever heard of BMW saying that they would have to do any coding because if I have it done after any DINAN updates it would erase the DINAN software? I had all of my communication modules replaced and now I have to do a Idrive update and MP3 retrofit, This 3rd party shop will do the software update at almost 10% of what BMW is charging.

Not sure what point your at, but most replaced modules will have to be coded. If all repaired modules have been coded to your car, probably just the Dinan updates will need to be done. Your Indy should be able to give you most of the latest Daten files. I think buying the battery 1st will be a good move. Make sure it it is fully charged before installing it. The programing will suck it down fast.

Good Luck!
