Sometimes you can reset the engine warning light by disconnecting the battery for ten minutes or more (be sure you have your stereo unlock code if needed).
That is not a good solution, it is better to diagnose and eventually fix the problem.
Have the car computer scanned with a code reader, the codes you get in return witll tell you exactly where to find the problem.
Here is the code list.
To get the codes the code reader must be connected to the car computer.
sometimes on Bmw you may need a Interface 16 pin Adapter, depending on the code reader.
Here is a home user code reader : PocketScan™ OBD II Code Reader (AXRCP9125 ...
Here is a good scaner.
Always better having the job done at a qualified garage.

The EML light will come on if you have an emissions fault , the car may drive ok but you may find you are using more fuel , it would be better to get the problem checked just to be on the safe side , regards mark.

The error shows as a "Turbo Charger Bypass Valve Control Circuit High" error. Let me guess, you don't have turbo, right?
Did you recently "top off" your last gas fill? If so the error might go away on its own.
Is there a lot of moisture where you live? Ignition contact might have gotten wet.
Possibly a piece of carbon blew out of the manifold.
Does the car stall when you stop or while taking turns slowly? Might be cam position sensors.
Sorry for the vagueness but without using a Peake analyzer tool to isolate the problem it makes it difficult to give you the exact reason.

"EML" is an acronym for "Elektronische
Motorleistungsregelung". Loosely translated from the original German for the BMW
owner means Electrionic Engine Power
"EML" is BMW's system name for electronic throttle management. The "EML" system, in it's most basic sense consists of an accelerator pedal (with an electronic position sensor), a computer module (usu. integrated with the main engine computer), and an EDK (Elektronische Drosselklappe or Electronic throttle valve). The EDK is also known as a "drive by wire" throttle. "EDK" throttles use a computer controlled stepper motor rather than a purely mechanical linkage (usu. metal cable attached directly to the accelerator pedal) to control the opening and closing of the throttle plate.
"Drive by wire" throttles are very common
on modern vehicles starting in the late nineties up through the present day.
"Drive by wire" technology enables very precise throttle control to improve
drivability and vehicle emissions, as well as many convenience features like
electronic cruise control, traction control & stability control.
BMW first implemented "drive by wire" in very limited quantities on the most expensive & sophistocated BMW models starting in 1988.
The latest generation of advanced vehicle
features to take advandage of "drive by wire" technology are radar guided cruise
control, accident avoidance control, autonomous-driving, and autonomous-parking
