Why does my traction control and eml light come on Bmw e46 ?

Hi
These are cleared via a diagnostic computer that all good garages should by now have.
Cheers

Eml is the throttle fault light for the electronic throttle control you will need to get the fault codes read to find out which end the problem or problems are at on the throttle control
Asc is the traction control and when wheel spin is detected it shuts the butterfly on the one throttle body until the wheel spin is reduced get the actuator in the wheel well checked for damage to the wiring to the throttle body

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.

"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 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.....

what is an Eml light? The traction control light is a common one, but Eml, never heard of that one.

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

EML,ASC light is on and i cant rev up 3000+ on a 2000 323i e46

Hi
Air flow sensor could be a problem.
Every time EML comes on the car computer will put the system into limp mode. To avoid any further damage to the engine.

once switch off, isolated and re-start will re-run the program and clear it temporary.
Ideally you need to get the car plugged in to a Diagnostic computer and see what fault code are stored.

Thanks

I Have BMW 325ti Compact E46 2001 model and the eml light come's on and the car just cuts out

As for the limp mode unless you have an expensive diagnostic system this usually has to be done by BMW (anything to get ya to a dealership!!). The comms problem, is the key turned in the ignition?
