Question about 2002 BMW 3 Series
Turn the key in the ignition to the point where all the lights come on (dont start the car) leave the key in this postion for approx 2 mins then turn it off and on again. This makes the ECU do a self diagnostic (you'll hear a double click in the engine bay when its done) this will solve most minor problems if this doesn't work you can buy a diagnostic interface for cheap which will describe the problem fully i.e. sensor malfunction.

"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
