EML Light Issue
 
I recently bought a 2003 325 ci with about 120k on it. I am a very mechanically inclined person, so I normally do all the work on my cars myself. I was driving the bimmer for about 6 hours after purchasing when the EML light turned on. I did a lot of forum research trying to figure out what it was. I took it to Advanced auto parts to have the codes run, and they told me it was the idle control valve. I took that out, cleaned it, replaced it. The EML light comes on, usually at lower speeds at this point, but turns off every time you shut the car off. it doesn't turn on when the car is sitting still, only when moving. I took it to a Eurosport shop then, and they told me the same thing, saying that the Idle control valve had thrown 261 error codes since the last reset. They said the best route was to replace the valve. I bought a new valve and just replaced it yesterday. About 24 hours later when going to lunch today, the EML light turns back on. I am rather confused on what this could be. If anyone else has this problem, maybe there is a common issue?

Shitty. I guess first/obvious question is did you replace ICV right? haha Either way don't think ICV would trip EML.
what exactly is the code are getting, has it thrown 261 codes or is the code 261?

EML normally related to your throttle body and accelerator pedals if you have drive by wire option.

Sk8orkidd 07-26-2012 09:04 AM

The code that was thrown 261 times was a p1500 (Idle speed control valve stuck open), which to me doesn't make sense because the idle speed seemed to be fine and it wasnt fluctuating. The other thing is I think it is temperature related, I live in orlando, fl so its hot a ballz out right now. It seems to want to turn the EML light on more when the car is hot, thus if driving around noon to 6 its about 97 out during that time of day. The only reason I tried to change the ICV is that was the most prevalent code on the system. There were no codes about failing Mass Air flow, or throttle body. What can I do about the drive by wire if that is the case? Any way to test that? I am going to the shop today, because they said they would re-diagnose for free because I already paid them for the diag last time.

What was the issue , did you fix the problem ?

alinfaraonu 11-08-2012 07:02 PM

I hawe problem ENGINE, EML and DSC,hand brake on all yellow.U find the problem pls help me

Dippinwandy 11-08-2012 07:25 PM

This sounds very similar to my problem.. Did you ever find out what the problem was ?

Sk8orkidd 11-08-2012 07:29 PM

No fix yet
 
No fix yet, but now that the weather is cold, the problem occurs much less frequently. But the car now has a hard time starting in the morning and is rough idle until the engine warms up. Seems to me that I have a faulty idle control valve or somethign that sense the idle in that area.

EML is throttle related , might be ICV aswell but not sure.

Wiring could be a problem so if you can get another harness for your ecu then try that :)

ICV will DEFINITELY throw you a EML, did it for me. The problem with mine was that the valve, although cleaned out, was actually stuck.

My resolve was to take the ICV out and take it apart to thoroughly clean it. All now resoled for me.

the ICV should open and close very freely, if you hold the unit in your hand a oscillate it, you will be able to see/feel it rotating back and forth. But you say you've fitted a new ICV? Actually New or a used one from elsewhere?

This sounds exactly like my symptoms

When i replaced it i got a used one off of a totaled e46

Barneyhyphen 11-08-2012 09:49 PM

I believe you MAY have TWO stuck ICV's, your old one and the "new" one from the totaled car?

Take the ICV apart to clean it. The three blobs on the end, that look kind of like rivets are actually allen bolts with a blob of hard epoxy stuff on them, presumably to dissuade you from taking it apart. Practice on your old one first. I did a little write up on it a couple of weeks ago. Search ICV by barneyhyphen.

update
 
I bought a refurbished ICV from autohauaz.com and it seemed to help for a while. I also did a valve cover gasket job and the oil filter stand gasket at the same time. The car had an oil leak, but that was solved easily. The funny thing is once i replaced the ICV the EML problem would only occur maybe twice a week and could be fixed by cycling the engine on/off. When the weather became colder (Florida) the car now barely starts in the AM and tends to want to quit when at idle, either at traffic lights or in the parking lot. Just last night i believe that the car is now misfiring a result of these problems. If i clean the ICV and the problem persists, what do you think it coulds be?

03E40sick 11-09-2012 11:14 AM

Did you check for any vacuum leaks, I would suggest to start with that, then clean the ICV, throttle body, and MAF... I get the eml,traction control, and brake ( all in yellow ) once a day at least .. Haven't not replaced anything yet, but my car idles good and there are no leaks at alll.. I have a check engine light with- idle control valve stock open which is code p1500 .. I might end up replacing that soon...keep us updated

Dippinwandy 11-09-2012 02:06 PM

I will open up my old icv once i find it. I replaced my intake boots, and i have a brand new oe maf

03E40sick 11-09-2012 03:27 PM

Do you still have the same issue ?

Dippinwandy 11-09-2012 05:22 PM

Yes i do.

Mango 11-09-2012 05:57 PM

If your car ever develops a fault such as this one, the best thing to do is do things that need to be done anyway. In this particular case, cleaning and resealing the TB, DISA, ICV, and MAF would be a great start.

Dippinwandy 11-09-2012 06:24 PM

I put in a new maf and icv,cleaned tb and im waiting for my new disa to come in the mail. Tomorrow i will check everything and make sure nothing is loose.
