Hold on you have an OBD2 reader that can read the SRS and no codes are coming up. You need to send it back. I have a Launch and it reads everything that can log errors. If you want a code reader get the X431 pro elite. It will save you money in the long run or you can get INPA via BMW tools with a K + Dcan cable. You can't troubleshoot a foreign car with a basic code reader. They are too complex.

I've never seen the BST itself throw the SRS light. It's always been paired with an error for a device apart of the SRS system (seat belt, occupancy mat, etc.), with us knowing it is the BST causing the issue.

BST throws an airbag notification in the i-Drive along with the SRS icon. I got thrown off initially because I had no airbag codes but I did have BST code in SGM. I cleared that, and the airbag notification and SRS icon extinguished. That's because BST works in conjunction with the airbag circuitry.

Mine throws the SGM fault 100-percent of the time.
But thanks to you, I have no more intermittent airbag notification. That was driving me crazy, and I did not want to do the BST bypass trick.

Yeah you were thinking the same thing I always thought. I was not going to do the bypass. I did manage to get a cable out the junk yard and soldered a resistor to it but never installed it. I have it just in case. I made it so it plugs into the existing plug. I wonder why no one ever does that.
