I want to ship my spare EZL to another member who is having problems. I am doing it at no charge up front as forum brothers need the help each other. If it fixes his problems he will send me a check.

We both have 1992 R129's, but the EZL part numbers are slightly different. His is BOSCH #0 227 400 826; MB#014 545 4232

Mine is a Bosch #0 227 400 722, MB #014 545 5732.

Do we have an expert out there that can tell me if they are interchangeable?

Thanks in advance.

There is no problem here, suck it and see. As long as the cars are the same the Bosch part numbers are not important as the mapping inside the EZL will be the same:thumbsup:

Lynn,
I called them. The response on the phone was: "Vee have zee latest technologies and equipment. Vee have much invested in research. Nobody else can match us. You send your unit, vee will test it ($120) and rebuild it ($499.99). Vee don't give out part numbers!!":mad:

:surrender:

I guess I'll ask the Stealer.

I'm going to buy a used EZL tomorrow for my 1991 500SL, there are two part numbers available from the dealer.

012 545 5732
010 545 4032

I found the 010 545 4032 in the local junkyard and it seems in good condition, I had no luck finding the other part number at all. Even this one was a very hard find.

My question is, what is the difference between both numbers? I'm afraid am so paranoid about these EZLs as I've had some bad experience with them and want to make sure that everything is right this time around.

Also, what preemptive measures can I take to prevent future problems?

Well, I'll ask them about the part number I found as well but I think my only current option is the junkyard. The car it came off seems in good condition (just cut in half :D)

Any news on the part number from you guys?

Actually, I have TWO SIX CYLINDER EZLs inplace of the original setup (long story). Ever since then, I've been waiting and praying for the day when I go back to the original set-up.
Hopefully that day will be tomorrow.

Just wanted to make sure of that part number 010 545 4032

Vee don't give out part numbers!!":mad:
I had Tom Bush BMW pull that crap on me. It used to annoy me soooo bad. I would be in for service and figure I'd get a price for some stuff I needed anyway, so I was standing at the parts counter asking "and what's that p/n?" and they'd whip out the old "Sorry, we don't give out part numbers". I was like "Man, I am just gonna walk into your own customer lounge and use your own computer to look it up on realoem.com, except now I'm definitely NOT going to buy it from you because you guys are dicks". Lol.

Over the years I was driving bimmers, I would say Tom's Bush probably lost at least $6k worth of parts business from me, easy. Heck, the MID display I had to replace twice was $680 by itself. The MB parts counter is muuuuuuuch friendlier. They seem to understand that being unhelpful and irritating to people isn't going to stop anyone from shopping around, but it will run the risk of getting the customer to avoid them even when they do have the best price.

whoops ,wrong year for that car

sounds like there could be a little confusion about the production date on one of the cars, 012 545 5732 is only interchangable with 010 545 4032 or an earlier interchange, 007 545 6932

your friends ezl 014 545 4232 is from the later version,production probably late in 92 fits 93-95 500sl
whats wrong with yours?,perhaps we could fix it (we do this!)

EZL interchangeable?

Hey guys, I tried searching, and failed. I tracked down my car's problem (only 4 cylinders firing, coil/distributor/wires/plugs not the problem) to the EZL. Great, now I have to find one. Just wondering if we can use any other EZL's in our cars? My part # is 012 545 5732 or Bosch # 0 227 400 722 and my car is a '91 Sl500.

I can't find any of these guys on eBay. Does anyone know how much these go for at 4mercedes.com? I would contact them but I'm at work and they close before I get off...

Also, another one of my fears is that I will buy a new one, put it in my car and it will burn out right away again due to a problem that burnt the first one...is there any way to ensure this does not happen? Since I'm not sure what ruined the first one, I can't narrow my problem down to heat or electric spike etc.

Thanks guys.

EDIT: UGHHH, I'm SO sorry. Thank you mods for putting up with this constantly.

Here is some that work with SL500
All tested and working

The 0125455732 is what you want, exact part number
Also 0105454032 is switchable

When you change the new EZL please change the new of heat transfer paste(white cream) at the back side of EZL, you can use the CPU paste and cover with food microwave wrap

That's my DIY heat prtoect trick, work very well to protect your new EZL

Another of EZL models please letting me know

Help - 1990 500 SL Ignition Module (EZL)

Hello,

I'm new to Benzworld and hope you can help me. I'm trying to help my father, a proud owner of a 1990 500 SL.

His baby has been on the shelf (approx. 5 months). We have been told that the problem is the Ignition Module (EZL).

We could use your advice:
Where can we find the ignition module?
Do we just need a new one?
Did anyone install a new EZL, but it still not work?
Basically, what is the best course of action?

Believe we are looking for Bosch# 012-545-5732 or 010-545-4032.

Thank you very much. It's driving my father crazy. Anything to help us is greatly appreciated. Hopefully I can fix it in time for Christmas.

-Mr. Astanehasl

Put p/n 0125455732 at AUTOECMS.COM and you will find that they ask you to call 877-687-3267 OR EMAIL [email protected]
Lynn, it wasn't the company above, but wasn't there a 'Rip off' company doing reconditioned units? I seem to remember they charged a lot of money, and the unit came back useless :eek:

James, I can't recall exactly what was the name of the company you are referring to, but one company to beware of is.. EZL - Ignition Control Modules - 4Mercedes.com

I have read of a few stories of how customers paid to have their module(s) or ETA(s) rebuilt and they were retuned back to the customer in faulty condition.

Worst part is customers were initially denied any form of reimbursement or refund of costs from my understanding.

To support the above statement, here below is a fine example relevant to this discussion.

DO NOT USE 4MERCEDES.COM - BUYER BEWARE

Thanks Ken, yes, I think they were the culprits!!!

I seem to remember a customer complaining that he left his SL500 with them, and when it was returned there was about 3000 extra miles on the clock, baby toys and nappies/diapers behind the seats, and a bill for $2000, and the original fault was still apparent :mad:
