Arrived home today in my 328 bmw all was fine went out later eml light was on and when i tried to start it it it just clicked under the bonnet and the headlights justcame on flashing like mad

Question edited to add maker.
Question moved to model category.

All your issues are electronic. The clicking and lights flashing and not starting makes me think it is the security system that is the problem. You need an auto electrician with a pro grade scan tool computer to diagnose. You have many issues by the sound of it.

A fault code has generated in the ECM.
Being that your car is a 1996 it is probably OBD II and will require the use of a tool to determine the error.

Most likely it's your O2 sensor. Has it ever been changed?

This link will show you all you need to know about determining the fault that is causing your light to come on.

The Service Engine Soon is for an exhaust emissions issue and the EML is engine electronics. Could be a sensor or something else.

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

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.

Yes, this sounds like a flat battery. You could try to get a jump start off someone else, so that you know it is definately not the engine. Otherwise, purchase a new battery and you should be fine.

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?

idle control valve,replace, low oil pressure maybe check level,eml light on,if not get plugged in and aquire fault codes.

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.

It sound like you are having a electrical problem.You need to check your electrical/ignition system,not all electrical problem the diagnostic machine can read.
