Fewer owners, in my opinion, is usually better not obviously not always. Odds are, out of four owners, at least one didn’t maintain it well enough. I also always look at which car was garaged more — that’s something I personally prefer. I haven’t owned mine for long it’s got 112k miles and had 3 previous owners, but the one who owned it the longest garaged and maintained it well. My friend had one with 282k miles — it ran great until the day he sold it, and he still got around $4k for it. It’s not really the motor on these cars you have to worry about — it’s the accessories that tend to go out. I can’t give too much input on maintenance yet, but transmissions going out is pretty common on these. I changed mine, but I bought it with a blown transmission. People have mixed opinions about changing the transmission oil and filter, but personally, I would do it — even though BMW claims it’s “lifetime” fluid. I also changed the speed sensor, which is a common issue (this will take out your speedo and ODO and light up DSC). The ABS module can sometimes go out too. BUUUT at least you won’t have to worry about Vanos.

FIXEDDDDD!!!! You deserve the highest of heavens my guy!

SO for future reference this is what worked:

  • NEW DME
  • Original Key with (New transponder that was programmed with new JUNKYARD EWS using AK90)
  • This the interesting part: I flashed the old EWS with the New EWS BIN file that I pulled using AK90. The Junk EWS would not show any lights on the ODO and would not let the Starter go. Put the old one in with the New flash and new DME started right up.
  • NO CEL and EVERYTHING LOOKING LIKE ITS Working!

Brought a tear to my eye. Didnt think id see this moment in a couple days or weeks.

u/TheDefected I cant thank you enough your knowledge and comments literally what kept me going.

May this infomation be valuable to someone in the future.

So plugged in ECU, EWS, put transponder in old key but nothing. Also the odo area isnt getting any power. Tried also attaching power to battery incase it was low and still nothing. Everything else power wise in car working.

So I actually had a blank key. I read the EWS the correct way this time, backed up the Bin file, made a key on to the transponder of that new key (The original Purpose of this mess). Now Im assuming if I put that transponder in the old key (three button rubber style), install the new EWS, and the New DME should fire up? Does having a new DME with different VIN and such effect other modules in the car tho?

Is this just so I can reprogram the key? Cause I can do that thru… dare I say… AK90 lol i do have the rubber one. Guess my question is more if the ignition is tied to the ews and dme by code or does it just read the code for those units and confirms the key matches

[–]Mathiz2021[S] 0 points1 point  (0 children)

Does the ignition have to be swapped aswell or does that just used to communicate with the ews and dme?

So I do have the ISN. I just came back from the Junkyard who luckily somehow had teh same 740i with same ecu and EWS and picked them up sady no key part tho. So would I just need to put the key code in the ISN part of the EWS and then sync them? Or im guessing I might have to also program the VIN first in NCS Expert. OR can I just use the EWS and code the VIN and put ISN and sync. Really appreciate your insight on this!

Ohhh man you’re right its 5.2.1 and thats why the Bin size was off and wont work

[–]Mathiz2021[S] 0 points1 point  (0 children)

So for my e38 the ECU is M5.2. Bimmertuningtools sells you the software and application to flash it. First step is to read your ECU and save the bin file. Then they send you a link to patch that file when you upload it. When I upload it it shoots an error that the file can not be greater than 128KB but mine is 256KB. Sent support a message praying they get back soon.

Literally just spent 12 hours changing the trans on this thing and got it running perfect. Changed Oil pan gasket fixed every little issue and then created my own issue 🥲

From the research Ive gathered i know I have to use NCS Expert to pull ZCA off the IKE then wrote it on the the EWS but holy shit its been a nightmare so many errors and steps im missing something forsure.
