I need a big favor from anyone on this forum: My EZL went bad in my 1994 E500 and the dealer want North of $3K for a replacement. The best price on a new one I've found is $2K. I need to know two things:

1. What other EZLs will work on my car? Years and model of cars please...and,

2. does anyone have a source for a new or used EZL? I had my car put on a flatbed to go to the dealer and they are charging me 4.5 hours of labor just to give me this bad news which I suspected all along.

0125455732 is the part number and any M119 engine controller should work but you may be better off posting your request in the parts forum.
FYI - the above part number is for a M119 engine SL500 R129. They run anywhere from $400 and up.

Tom, the part number I was given was 0155456132. Apparently the same number ending in 6232 will work as well but that part is no longer made so I'll have to find a used one. Can you reconcile this?

Thanks again.

Even Lawyers- no offense intended - U probly couldn't help it

Get your car outta there fast. They took it off the flat bed and plugged it into their HHT - got a code, verifyed it and had the balls to charge you 4.5 hours @ $85.00 per or better to call and tell you that

What are you on retainer with this dealership and they just wanna get even?

Any MB boneyard will have at least a dozen on hand. Check the Mechanic forum for a referral to a local non dealership mechanic. Get the HHT read out from the dealer - at 4.5 hours, you paid for it and they should give it to you.

The independant shop will prolly quote you no more than a K or so to do the pluck/chuck/reinstall.

Tom,

They said they couldn't pull the code because I had unhooked the battery which cleared the code. I unhooked the battery hoping that when I put the leads back all would be well. Without the code, I guess they had to do lots of troubleshooting. FYI, their hourly is $90. If they had just driven the car for .5 hours, I'm sure the check engine light would have come back on and they could have pulled the code.

Well, it seem I am going to have to get the car towed back because I'm told that it no longer starts.

Here's a link to my E500 so you can put some sheetmetal to my name -- http://www.mbcoupes.com/500e/1994E500.htm

Regards,
Khari

Khari- could you help me understand why the EZL died???

how many miles on your car before the EZL went bad???

Has your car been heat soaked or lived in a hot climate? flooded or been in an accident?

Its hard to believe that this part is soo expensive and not available "new"...on general principle, I would seek out the least expensive "new" replacement for my own peace mind.

Let us know what turns out!
Best regards

'94 E500 (44k)

I ran an inverter though my cigarette lighter with an extention cord powering up my laptop, cable modem and wireless router. I did this because I had no power, no phone, no nothing thanks to Isabel. I believe this is what caused the unit to go bad, but I can't be sure. FWIW, My E500 has about 101K on the clock.

Just to be clear, the part is available new. The dealer wants $3100, wholesale is about $2500 and I have found the part new for as low as $2000. I am looking for a used replacement, however, and there seem to be a few that will fit the bill I just haven't found one yet. Hope this clears things up.

Here's a stupid question...What is a EZL?

ignition control unit/module/brain.

What is the actual problem with your vehicle? And what tests were performed to conclude that your EZL unit is the cause?

Thanks for the link but I have seen your fine machine before. I did a search of this forum (Ignition Control Module) aswellas other aficinado web sites. Since all other electrical/electronic components assemblies and sub assemblies are protected by fuses, I have my doubts as to the inverter frying your car computer. Since the dealer states that they did 4 hours of diagnostics, ask them if you can speak to the tech or team leader who did the manual diagnosis.

Check list it.

Did he confirm that all fuses are fully functional with no hairline cracks(remove-visually inspect, test, replace if corroded ends)

Did he check condition of wiring harness(one going from brain to TA and other components notorious for failure - your car should already be on it's 2nd or even third harness.

Last but not least, did he remove the EZL and test on other similar vehicle to see if it did not work on that vehicle.?

When a certain MA dealer wanted to replace mine, I called the tech and asked him to perform that task and call me back. He did as I asked as he thought he was on the clock regardless of the result. It worked in the other vehicle and he reinstalled it back in my car. When I picked up the vehicle, I asked to see the service manager - told him that I refused to pay for incompetence - A simple hand held HHT test would have told the tech that the computer was AOK avoiding the R&R

Tom

I just put a call into the dealer asking the tech to phone me so I can run those questions by him as well as a few more. By the way, that part number you gave me was for an SL CIS unit. That's a different system. What makes you think it will work in the E500? I just found an EZL off a 95 S500 (part# 016 545 1432). Does anyone know if that will work?

Khari


Answering my own question: yes it will work.

the 129 model SL with the 119 engine is a very close match to our 119 engine. I was told that the Ignition Control Module (EZL) is the same and the different part numbers pretty much tells the parts department which vehicle it goes in or came from. As it controls ignition only, logic would dictate that all M119 engines would have the same firing order, knock sensors etc, etc, etc. German engineering does not always follow simple logic so I would ask Gilly, M.B.DOC or your own 90.00 per hour tech if the EZLs are interchangeable.

Thanks for the info..

I just called the dealer and they said the EZL was the same unit they replaced in my car 8 months ago.

My wife took the car out for a spin with her mom to go shopping. Next thing ...she calls ..the car won't start in the parking lot. I drove over to jump the car..when I got there ..she was able to start the car..BUT..NO POWER...DROVE LIKE 4 CYL. Flat bed came over the house and brought it to the dealer. Yup..EZL..bla..bla..

Wierd..The part was for about almost $2k and labor was $100.00 to install. I usually see it the other way around.

Under warranty...$50 deductable.

It's the EZL. Tech popped in one from another car and my E500 started up and drove fine. So now I need to source one fast. Off to surf I go.

One question: what's the difference, if any, between an "EZL" and the "Brain"? When I used the term EZL it's like I'm talking a different language to dismantling yards.
