got a dme out of a 325is with a build date of 04/94. it was in a running car, so i went to put it into my 02/94 325is. all it does is crank and wont fire. do i need to have this thing reprogrammed or is there something different i need to look at.. please help anyone who has knowledge about these things:help

You need to get also the EWS in that other car. Any used DME is mated/aligned with its own EWS for life.

You could always bypass the EWS system by cutting a certain wire.

EWS didn't start until 1/95. Neither of the OP's cars have it.

Uhhhhh, no you can't.

Maybe you can't, but it is very possible.

The electronic anti-theft system known as EWS was first introduced in january of 1994. The early version of the system uses a starting inhibition module to interrupt the ignition, the fuel injection, and teh starter motor. Starting with models built since january 1995, E36 cars come equipped wth a sophisticated coded electronic immobilization system called EWSII.

Easy way to check, do you DMEs have a Burgundy label, or a Silver label. Burgundy = Non-EWS, Silver = EWS positive.

To bypass EWSI, you have to take the protective rubber boot off the connector to the ECU and cut wire #66. It should be solid green but it can also be black/violet according to the Bentley wiring diagrams. Just cut the wire and dress both ends with some electrical tape.

There are EWS delete chips for mating EWS DME's to non-EWS cars.

so to clear this up a bit.. your saying i cant just take the dme from an 04/94 car and put it in my 02/94 car? or can i swap the chips or something

If youre DME has a silver label, it is equipped with EWS which will prevent you from swapping the DMEs and chips. If you cut the wires, as mentioned before, it should work just fine.

they are both red labeled 413's so now what

Then they are non-ews DMEs and should work in the car. Could you get the engine to work before with your original DME? Also, what problem/s are you trying to fix in the first place?

Also, what problem/s are you trying to fix in the first place?motor ruuns on the old dme. but the cel lights on throwing the 1211 code. which the dealership told me thats a sign of a bad dme, so i bought one out of another running but wrecked 04/94 325is, put it in. and all it does is crank.



now the symptoms my car is experiencing with the original dme in it...

while driving down the road.. the cars throttle cuts out to where if i push in the clutch itl drop down to 500rpm and not let me throttle up. its like a dead spot. then it kicks back in and all is normal.. itl do this every couple minutes reguardless the speed. its real hard to explain this without someone seeing it for themselves. i do notice that when it hits the "dead spot" i hit the throttle and its like the motors died and goes into some sort of limp mode for a second or two. then kicks back on and goes like it did before


sorry for the babbling.. this things got me goin in circles trying to figure it out

guess noone can help me

A lot of confusion usually arises when you discuss engines based on engineering series and years (of production or sales which can be different things). Sometimes engines are different within the same series in different years (rarely, even in the same year).
M50 engines started in 1992. M50TU( with vanos) started in 1993. M56 started in 1996. Naturally, the DME's will not work from one to another (EWS or Not EWS).
And furthermore, we all know that today's cars are still sold next year and called next year's car.
Just to make things simple, just post here the 2 part numbers in each DME (both the small sized and also the bold p/n). Then I will try to see what they really are for and if they are interchangeable.

No, the EWS delete chip from TRM will allow you to use a silver-label 413 in a non-EWS car.

i dunno what you mean by part numbers.. i can give ya the vins off both of them

my original one from my car is vin#WBABF3322REF46501

the one i bought to replace it is vin#WBABF4329REK13571

No, the EWS delete chip from TRM will allow you to use a silver-label 413 in a non-EWS car.

From what the OP has stated, they dont have a TRM chip, so theres not much help there, but good info nonetheless

Sorry, had to jet to my other job. Have you tried swapping the chips or checking the new DMEs internals for damage? Is 1211 the only code you get?

No, no, you seem to have missed the mark. TRM offers an EWS delete chip to use an EWS DME in a non-EWS car. I really thought I said this as clearly as possible, not sure any other way to say it.

I understand perfectly what youre saying about the TRM chip. I was saying that the OP doesnt have EWS on either of the DMEs so whats the point of talking about the TRM chip?

From your previous post, you made it out to sound as if you thought the DME needed to have a TRM performance chip in order to utilize the EWS delete. My bad, I mis-understood.

Any OBDI car can be bypassed by cutting the EWS wire. Pin 66 IIRC.

OBDII cars must be alligned.

No harm done. :)


Deetz, do you have fuel and spark when you use the 04/94 dme?

im soo confused i dunno what to do here.. so can the dealership check the dme out to see if its good?

The dealership may charge you to check if the DME is good or not, so inspect it yourself.

1) Check for spark and fuel with the 04/94 DME installed. If you dont have either, the 04/05 may have a faulty chip in it or a broken circuit somewhere.

2) Open the DME, check for damage....hot spots, burn marks, broken cicuits, and check to see if the chip is ok. Are you sure that the DME that you bought is completely stock? Ive seen chipped DMEs cause problems with engine starting, so make sure to check and see if its the stock chip.

3) Last resort before dealer. If all checks out, cut line #66 to the DME which disables EWS, even though you dont have it, but you never know, bmw has done wierd things with their vehicles. When you cut the wire, make sure you cut it so that it can be reattached if you choose to in the future. See if that gets the engine to start.

well the only way it could have gotten taht way would be in shipping.. it was pulled from a running car. and which one is the chip? i have no clue what im looking at

bingo!! thats what it was.. the damn dme didnt have a chip in it. AT ALL!! il install my chip and see if it works

:) Let me know if your car works after that? Also, not to put a damper, but if your chip is faulty, it may still cause 1211.
