EML, Traction control, and Brake light all of a sudden came on *HELP*

I had this exact problem shortly after I bought my 2003 330ci and it turned out to be the MAF that was causing the 3 lights. Previous owner had replaced the MAF and used an aftermarket part. Replaced with a new OEM MAF and also had vac. leaks repaired. Problem solved

I have the same issue today after filling up with gas. All three of these lights popped on along with my low coolant light.

im having a similar issue with mine now .. but its the eml tc and check engine .. but when i shut it off and restart it it goes all off except the check engine it takes a lil longer to go away but it eventually leaves.. this is the second time its happen n the first time it was cuz i had a leakage in my radiator and needed to change my rack and pinion but now i have no clue why its doing it again after long months of not doing so. so hope you find an answer!

after I changed the intake lower boot it never happened to me again.

As the throttle is part of the xSC system that light (and brake light) will come on aswell.

That the light isnt permanent is usually a sign of this happening.

This would be the best answer out of everyone who replied on here. EML is usually related to the throttle body. I would try these steps:

-Clean throttle body flaps inside and out with throttle body cleaner. Removing it is best way to clean it.
-Clean Idle Control Valve (IDC)
-Make sure there are no rips in boots. If so replace.
-Last option is to change Throttle body or MAF if the problem is still not solved. The potentiometers imbedded in the TB is most likely not working properly.
