I wanted to purchase a spare EZL since my car has a used part already installed. The EZL that is currently installed is 006 545 7332 and I want to make sure it’s the one correct for my application even though it seems to work fine for a early production 86 3.0. I see a number of eBay listings for a 004 545 4632. I tried the classic parts look up but didn’t get far. A quick search on this forum unde EPC didn’t help. I will admit I’m not the best finding information sometimes.

And to be fair the EZL on the standard M103 engines is very reliable overall and rarely fails (maybe I'm tempting fate with that comment) but ours is almost 230,000 miles old..!

Thanks for the responses. I’m glad this model is relatively reliable. The original one failed a couple years ago according to the previous owner. I ordered 2 used ones that had different part numbers than the one that on the car. I will try them back to back and report any differences I might feel. Like others have reported I probably won’t feel any changes. The US market uses a 750 ohm calibration resistor which might make more difference than the module itself.

Good shout! Ours and Plinkers are non CAT engines so perhaps there is a difference in the EZL life or reliability. Not sure.

I agree but as said, reluctant to tempt 'fate' by bragging about my M103 EZL's. I have almost 300,000 miles on one with no issues when I retired that car. I wouldn't hesitate to slap it in another car and go.....with another used one as a backup to the backup....:LOL:

We have no 'science' data to back this up, but a lot of us here think that a contributing factor in the early demise of the EZL.....could be the wrong spark plugs(resistor type).

Although Ray over in France has somehow pissed off the EZL gods with his car.;)

So the one i found from the American site is wrong You say it is 16 numbers and letters in the vin .,,some one is wrong . I can see that WDB 30 is two numbers were others have 124 so it gives an extra number ,..

Not sure! All I can say is that the photo in #17 is from an original MB, USA publication for 4Matic cars and shows the 17 letters/numbers. So I would say its correct...!
