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.

When your ASC light is on this is to let you know your Automatic Stability Control system is switched off press the ASC button Till light is off /ASC is on this works with your rev limiter and should stabilized your idle. If the problem persists have your throttle control unit checked as thi can trigger the ASC light as well and may also activate the ABS light if not fixed

Check to see if your brake pads and rotors are in good condition. Or if you have replaced the pads yourself and have not reset the wheel sensors this would cause the ABS Antilock Brake System light and the ASC Automatic Stability Control light to stay on as the ASC uses the ABS brakes with computer assistance to control the traction of the car if not fixed it can affect your rev limiter and slow performance

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.
