so i was driving today and the ABS light,DSC light(as if you were holding it tho,all systems off) and the light that comes on when you raise your e-brake came on in yellow.(6MT)
i got to a friends house and checked the manual and it says vehicle electronics failure....
the weird thing is that it all keeps going on and off, it did it like 4-5 times now.

i tried to search up something but i got mixed solutions. 1 thread said they unplugged the battery for 20 minutes and all was good, another said it was a rear wheel bearing that has some sensors on it,another said they had to replace the entire battery and the worst story was one about some 2400$ ABS pump!!
any help would be greatly appreciated!
i just lowered my car on BC coilovers and got an alignment yesterday if that helps.
thanks!!

car is an 07 335i e92 FBO JB4 just in case it helps.

now im confused....in the manual it says when you have a red car on a lift and then the ABS light,DSC light(as if you were holding it tho,all systems off) and the light that comes on when you raise your e-brake came on in yellow(6MT) on your dash it is vehicle electronics failure.

but then it also says when you have the ABS light on where the red car on the lift would be with the ABS light,DSC light(as if you were holding it tho,all systems off) and the light that comes on when you raise your e-brake came on in yellow(6MT) BUT ALSO the flat tire monitor light comes up on the dash that it could be driver stability control systems including ABS,Xdrive, and flat tire monitor have failed.

the problem is that the exact configuration of lights i have on is not in the manual, i have the ABS light in the center screen(where the red cor on lift would be) and on the dash i only have ABS,DSC light(all functions off symbol,circle and triangle with !) and the e-brake light in yellow. no flat tire monitor light. the flat tire monitor light only shows up when i go through the check control menu with the BC stalk on the left side.

im seriously confused now,sorry for the long ass posts but im trying to give the best detail possible so i can get some help and try myself before going to a shop or worst the STEALERship

Get codes read would be the only way to get a definitive answer unless you want to start throwing money at it randomly.

Battery can cause weird electrical gremlins too. How old is your battery? If it's the original, it's probably on its last legs anyways so you might as well start with a new one.

It could be the steering angle sensor is going bad.

As stated above get the codes read to make sure.

I had abs dcs and start assit inactive it turned out to be rear speed sensor

no codes guys that was the first thing i checked for and yes the battery is the original from an 01/07 build date

There are some weird relationships between electronics in these cars for sure!

I had DSC, ABS and FTM come on 2 days ago, it was a faulty left wheel ABS sensor.

ABS sensor failure seems to be the cause of a lot of unexpected warning lights so I would begin there.

I too read the threads about failure of the ABS pump and $2,500+ for replacement, that goodness it wasn't that!

Good luck.

hey i just lowered my car as well and had these lights come on before i got a chance to take it in for alignment. after alignment about 70-100km the lights went away, its been 3 months now and i havent had an issue .

You need something like INPA to scan the other modules for errors. It won't show with a normal ODBII scan tool.

If you are on the original battery it is going out. Your car is six years old. Time to get a new battery.
