Loud explosion inside cabin Z4M

RossBMWZseries · 04-08-2018, 08:23 PM

Ok so I removed the built in screw, replaced it with a new one, new washer and nut as well, worked just fine. The BST has been replaced and car fired up right away. I obviously still have the air bag light on. I’m gonna observe all this week to see if I continue having the electrical symptoms. Once I get the scanner I’ll clear the codes and take it from there. Thanks to all those that took the time to respond in this thread. Without you, I doubt I would’ve been able to replace the BST.

I always thought this wreaked of over-engineering. Does anyone know what other manufacturers provide a BST equivalent? I also wonder if it has really saved lives.

You're right.
I thought this was just one of those new things that all cars now have, like fly-by-wire throttle.
Or maybe a new DOT requirement.
Every Google hit for "Battery Safety Terminal" has BMW in the title.

Further evidence to support bypassing it.

You only found BMWs in your search because "Battery Safety Terminal" is BMW's name for it. Mercedes Benz calls it a "Pyro-Fuse".

Thanks.
That occurred to me, but I was too lazy to try and think of other names for it.
