I have a 2006 Cooper S JCW, which gives problems. I have an airbaglamp, which is on. It trows an error code 06, which means right airbag in seat. But I cant find the problem to why it is on. It is not the connector under the seats, I have changed them and checked the connections again and again with a multimeter.Here is what I have tried, without any succes.
1: Tried to put in another seat, from another car, no succes.
2. Tried to change the connector under the seat, no succes.
3. Tried another airbag control box, it throws the same faultcode.
4. Checked the wire between seat and controlbox, with multimeter. It is ok.

So now I have given up, can anyone give me some help. The car has had an accident, but no airbags were blown up.

 

Maybe a wiring diagram can help me, but where can I find it ???

 

I have found the reason to the problems. My B200 airbagtester said faultcode 06 I thought, but it was 0b instead and that did change where the problem was. 0b is battery + cable which is defect by the battery and not the right seatairbag as I thought and has spend a lot os time to find out what was wrong with this seat. So read the codes very carefully, when you have a B200 Tester.

 

So did you fix it? I got the 0b. I'm thinking new battery cable!

 

The AIRBAG WARRANTY WAS EXTENDED on MINI's...so no need to worry...if the light comes on, just bring it to the dealer...FREE!!

 

I was told by my service manager that the service is free only if it is related to the wiring harness. They charge a 1 hour diagnostic fee to check the problem, and if it is not the harness then you have to pay. If it is the wiring harness then it is for free.

 

Fault code of 0b on my B200 lead me to the battery squib. Upon inspection of the battery compartment in the boot ('06 MCS), a thin coating iron oxide was evident. I had noticed the carpet was wet after quite a large Nor'easter a few months back, but did not realize the extent of the water collection in the battery compartment.

I believe the iron oxide is either creating a bad contact on the connector or has affected the actual squib. I spent a couple hours attempting to clean the contacts to no avail. I'm going to attempt to jumper across the connector. Worse case scenario is to replace the battery cable, $300+ for the part and many hours of my labor or reports of $700+ for MINI to do it. Now the big question: How much is my weekend worth?

The crazy thing is after the huge blast of rain last week, not a drop of water in the boot. Maybe I didn't have the hatch closed all the way? (Water under the bridge, so to speak.)

 

Folks were using the BMW kit to rebild the battery diconect box/squib...but I think mini now sells one...much cheaper than replacing the entire cable.
The kit is the same as any of the rear engened bmw's...our mini has the same parts. Might be closer to $150 for the kit..but it has been a long time since I saw a thread on the kit....

 

I haven't had much luck locating the actual part# for the BMW BST(Battery Safety Terminal) kit, so if anyone has some info.... (The number I've found is 12421733937, which costs as much as a complete, new MINI battery cable w/ squib.)
