My bmw e46 320i 2003 had lost power and ive noticed that EML light is on, it wont accelerate

check throttle body

misfires are also caused by low fuel pressure injector electronics faults and faulty injector tips . Replacing plugs is half the fix

"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.

The "EML" warning light in a BMW indicates a problem with the "drive by wire" throttle control system."

"EML" is an acronym for "Elektronische Motorleistungsregelung". Loosely translated from the original German for the BMW owner means Electrionic Engine Power Control.

"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 systems.

get car onto diagnostic machine to find the fault, then you can decide if you want to fix it or get the garage to do it for you....
ive been in the trade for years and with modern cars guesing whats wrong is too costly..computers are good for somethings.....

It's not an old scool cars anymore.
No advise is possible untill you take it to workshop and let them scan it , I'm sure ECU stored all information and fault codes.

328 e46 eml light came on now wont start can anyone help please

These lights are computer readings. When a sensor reading goes bad, it tells the computer, then lights up the dash light. What you need to do is go to your local Advance Auto, or Auto Zone and ask for a computer diaglosic test. They will do it for free. If you have a car that they can not plug in to like a Ferrari, then you should go to your car brand's dealership. A diagnostic test will tell you exactly what sensor is reading trouble and send you down the right path to repair instead of running around.

you could have one of many faults. It would be dvisable to read the fault memory of your engine mangement unit. sounds like your throttle housung unit is more than likely your fault, but is impossible to know without using a diagnostic computor

I finally fixed this problem!  Not sure if it will work for everyone but it did for me.  My new mechanic said there is an electronic 10 pin connector hooked up to the throttle body and mine had 2-3 pins that weren't making a good connection....THAT'S IT!
