I installed my BMS stage 1 in my '12 335i. The car idled fine for about a good 5 minutes. I drove the car and got a "CHASSIS STABILIZATION" warning. Below it said, "Drive moderately, consult nearest service center"... It went away but still... WTF??? I did remove the main negative battery terminal when I installed this. I wonder if that has anything to do with it.

If you accidentally installed connectors 3 & 4 with Stage1 it could be related.

Nope. Just the first and second connectors.

Might just be from disconnecting the battery but if it comes up again I'd contact BMS for technical support.

Did yours turn off shortly after notification?

Mine does it one time every-time I install/uninstall it. Seems normal.

Weird. If mine persists, I'll probably sell it and just go with Dinan. I got BMS because I thought it was cost effective. SMH.

Yes went away also I was in sport mode and kicked me into comfort mode when it happened

I never had an issue like you described. I did, however have something similar when I installed Stage 2. It pulled up a random code that I can't remember what it was, but it didn't read as important. I cleared it and it never popped up again, even after uninstalling and reinstalling it. To note, I never started the car, just the power when it popped up.

I don't think it's an issue, just something that is happening when you disconnect the battery and installing it. If it never happens again, I wouldn't worry about it.

This is why I am yet to install the jb1 since it doesn't auto clear codes, and surely some sort of code pops up when you get that error message that may lead the dealer to suspect it being tune related

I don't think it does. Could always get a code reader or stage 2 to check. I got a code the first time I installed stage 2 and it had a note to ignore it. I cleared it and it has never come back since.

I could be wrong though...

I just know my old JB+ on my e90 threw a tuner code that was hidden when i got it scanned by a buddy of mine's BT tool, and that "wasn't suppose to throw any tuner codes"

My car already had the sudden loss of power a couple of times so I know i will be bringing it to the dealer soon to get that checked out, and can't risk them seeing anything at all in case something major fails.

I think the stage 2 would be the way to go for me anyway if it auto clears the codes.
