I had to have my battery changed about a month ago.
I had Triple A roadside so they came and changed my battery for 150.
The guy didn't seem like he knew what he was doing and he even asked for my help so I did. As soon as he was done my my engine started up no problem, but my dash was out. He told me to take it back to his shop and they replaced a fuse. Everything seemed fine and I left but my airbag light came on. Didn't think it had anything to do with the battery I went to look it up online. I assumed it was the passenger side sensor since there have been problems with my model 2006 325i. Took it to the dealer to get it checked out. Apparently I need to replace some cable with an explosive charge for the battery?? Costs about 1000, and I am currently talking with Triple A for liability. Can anyone explain what happened?? If it was the fault of the battery replacement, or just bad luck?? Thanks.

Sounds like AAA messed up to me. Here is a link to battery DIY which should help explain things.

Sorry to hear that you are having this problem. This situation only reinforces the adage that you never, ever, take a BMW to a repair technician that is not fully trained and educated on the repair and maintenance of BMWs. BMWs are (over) engineered differently than other cars; it's been that way for almost forever, and even simple tasks such as oil changes or battery replacements have special techniques, or parts that are not normally associated with like repairs in other car brands.

Most likely the tow truck driver damaged the Intelligent Battery Sensor (IBS) that is built into the ground cable. Make AAA pay for the repair. It is not your fault that AAA sent someone out to change your battery that had no experience with BMWs.

First, make sure the battery is firmly latched down. I had the same warning and took it to the dealer. They told me it would need a new terminal clamp. This is part of the SRS system to blow the battery terminal off in case of an airbag deployment. Turns out the terminal clamp was fine. The battery retention clamp (that holds the battery in the tray) was not even screwed in (don't know how long it had been that way) and going over bumps would shift the battery enough that the sensor plug going to the terminal clamp was worked loose and giving random codes. I clamped the battery back down securely and removed the sensor wire, and with a small screwdriver spread the contacts apart ever-so-slightly to ensure proper contact and I haven't had a problem since.

Don't trust the stealership. They probably read the code (and it says something like "Battery Terminal Clamp Fault") and that's as far as they looked into it.

Here's the exact code as read by the BavTech tool:

93B2:
ZK10 / Security battery clamp
Error will cause a warning light
Error is not currently present
Test conditions have been completed

Here's a video of how to remove the sensor wire:

Yeah, big mistake. Have you looked at the DIY for the battery? http://www.e90post.com/forums/showth...ht=diy+battery

It is not just removing the black and red cables. A little more involved and to to watch for, especially for some grease monkey who is in a rush and is fiddling around with it on the side of the road. If it wasn't on the side of the road, for $150 you could have had a knowledgeable INDY change it for that price.

similar thing happened to me, I reset the code with INPA, hoping to never see it again

The light came back on the next day, so I am assuming my cable as shown in the video is loose or disconnected. Can someone show how that cable is connected on both ends?

Check that the new battery is a good one!....if it is, check the connections, especially the black ground wires for good connection...make sure there is no corrosion anywhere...this will really mess with getting the current to the car.

This is probably BST. Check contacts near battery, BST is just near + on battery and there is small connector, shake it, disconnect, connect again.
