Eml light went on BMW 325i

Check for a weak solenoid (spelling) on top of starter. Magnet too weak to throw out the bendix.

he first thing is a compression test to check for gasket or cracks ( any qualified mechanic will know that)
next is to check if the scan tool in use has the right protocol for bmw electronics
there are plenty of manual checks that can be done without resorting to a scan tool

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.

battery is new i just hear one click from the starter area light radio horn windows all work ?

If it makes no noise when you try to start it but the lights, radio, etc. all work, replace the starter.

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.

replace the fuel pump relay

sound like wheel sensor.most time when car is moving and abs light come on its the wheel sensor is loose or wiring problem at the electrical connector or sensor going bad.

Yes prob solved. When the battery went low the transient generated when I tried to start it caused a glitch in the computor management system and I reset it by removing and reconnecting the battery. All now working.
cheers
