Our 95 E320 will not start. I checked the computer and it came back with 4 flashes which I then looked up and found out that, that means there is something wrong with the "Distributor Ignition Module". Can anyone help I have taken the intake off and the metal cover over the spark plugs and can not visualy see any thing wrong.
Oh yea it started on day and then we had solid rain for two days and it will not start. I thought it was humidity but it is dry now and still will not start.
This has happened in the past but I would give it a few minuets and then it would start but this only happened a few times.
Any ideas or advice would be helpful.
Thanks

It sounds like your diagnostic code is telling you the problem. Ignition control module. Not sure on your car, but usually can be found mounted on the wheel housing in the engine compartment, driver's side. I don't know if you can get one here at Parts Shop, but I think they can be pricey.

On the 1993 & later E-class W124 chassis with M104 engine(like yours) there isn't a seperate ignition module. However the OVERVOLTAGE relay must power-up the fuel/ignition system module. Part number 000-540-67-45 is the *modified* "GOOD" relay part.

I took the modeual out and there is nothing visualy wrong with it (I know you can't tell from the outside), but is there a way that I can test it to see if it is working or not. MB Doc how did you know that is the problem. Could it be the ignition module, or something in the ignition system.
And when You say "... is the *modified* "Good"..." what do you mean.
Sorry for all the questions.
Thanks

Code #4 on E320 is AIR system. [air pump]

The OVP relay has been updated to the new posted #. They caused your exact problem. There is also a fuse on top of the relay . I would check that first.
If it does not have the new #,[ on the side of the aluminum can], change it before it dies. It will.

Arthur ... Is this an item that I should change even if it is not broken on my '95 E320? Sounds like I should.

Jim,
I would. Cheap Insurance.

Check the old first. As they were so trouble-some, it may have already been up-dated.

The old one will say "Siemens, Austria" on the side, part# 000 540-52-45. It is behind the bat. Remove the plastic shield and it will be a tall [5'] aluminum can w/fuse on top. It does have a hidden nut/bolt on the side to secure it, so look for that before trying to pull it out.
Fast Lane has the replacement for around $50.

PS I did put the clutch in that Fella's 190SL I told you about. He has had it from new. He is 80 yrs young and could not have been Happier.
See ya,
Arthur

Arthur ... Thanks again. I'll check it tonight. Any thoughts on the cause of my starter problem? (http://www.peachparts.com/shopforum/showthread.php?threadid=19981) The starter should come in today but I still don't have a good theory on what happened to burn out the starter. The spring in the ignition switch seems strong. Could it be a bad lock out relay? There is not much else in the circuit and it is all hard to get to.

Jim,
I did see that post and did not have anything to add to SB's answer.
Kinda glad I read it, 'cause my Wife has enough keys on her's to not only lock it in start position, but bust the key right off.
I did notice one time on mine that, because of the tunnel of the ignition switch with the trim, that with only a few keys , you can get it jamed in there. Happened to me , but only once.
My guess would be just dry lube.
Arthur

Arthur .... Thanks. I don't feel quite on an island if several knowledgeable posters also draw a blank. I'm a computer guy where if it fails once, it will fail again if you don't find and fix it. I was thinking about wiring a buzzer to the starter so it would buzz whenever the solenoid was energized. I could then give her clear instructions.... If the engine is running and the buzzer is buzzing, turn the key off. At least she wouldn't destroy another starter motor.

Hey Arthur where did you get your code information (#4) on the flashes? I got mine from "JimF" on his website. I don't think that it is the air pump. Because the computer came up with a Ignation problem and the moduel is a ignation component. Well anyway can you tell me were you found the codes at.
I am just about to order the moduel from parts shop.
Thanks all!

I just ordered the part and when I typed in the new part number the old one came up on the screen as the one to be sent. I don't know if that is a mistake on the computer or what but if I get a part with the old number should I send it back? I think I should.
Please advise (I forgot who runs the parts shop)
Thanks


Sorry I ordered the part from "Fast Lane" I guess it is the old part which I do not wan't. It is $50.90 on FastLane but on Parts Shop it is $62 (but the one on Pats Shop is the new number
Well I sent an e-mail cancelling the order untill I make order of the situation.

I assume you are talking a code #4 on an E320-104.992
eng.
The codes on Jim's site are for S500, not 124.032 chassis.
Did you get this code from the led socket?
These are emission codes and code #4 is AIR.
If you send me an email , I will send you these codes.
Arthur

. . . read wrong code

Subman,

You should have read the codes from the DIAG module, (Menu#5), which is "AIR inoperative" as Arthur said.

Yes, some of the codes are different for your auto, but most are the same.

LOL, I figured out how you got the that code!! You interpreted the Menu #4 (4 blinks in your case) as the place to look!

Here's how it works. The LED/Sw combo reads out codes ALWAYS from the DM (Diag Module). You always go there first to see what's it telling you. That's Menu# 5.

Of course, if you have a scanner, then you can read all of the ECU modules for their individual DTCs. Make sense??
