Did you read the EWS docs? Specifically where the codes are stored. It is not just in the ews module and keys...
Do you have or know of a walk through to delete the ews? I have inpa, ncsexpert, winkp, bmwflash and the inpa/dcan cable.I work on car for a living and ran into several ews issue and I know it looks at the prndl switch for an input if it’s not in park or if the switch is bad that car will not crank or start. Also if the transmission control module is dead no communication there will also be a start issue. That’s not the only input it looks at looks at several. If you program for no ews that would be your best bet and go from there

I am trying to use bmwflash, it says connection successful, but then just sits there when trying to download the full rom. I let it sit for over 20 minutes. I also tried to both download full rom file and the read one.
On the read one. 2% downloads, then asks where do I want to save it, then gives me the error file size is incorrect.
I am able to read the dme using INPA.
Any assistance is greatly appreciated.
Yes, I am able to open INPA and it communicates with the DME. The same with MSSFlasher. BMWFlash says it communicates, but will not download file. The cable I am using is INPA / Ediabas K+DCAN USB Interface Diagnostic OBD Test Line Scanner DIS. I got the link from BMW Doctor when I was watching on how to use INPA and NCSExpert.Because I’ve answered here, I’ll continue to do so, rather than in the other forums you’ve cross posted in.
Because you have an M5 DME (with no key) in a 540i you cannot align the M5 DME to the 540i EWS.

Because the engine cranks with the 540i key and EWS it means all you need to do (and actually can do with what you have) is disable the EWS in the M5 DME (MSS52).
What cable are you using?
This is the most likely reason you’re having communication problems.
I find that if I can open INPA and communicate with the DME, you can then close INPA and open MSSFLASHER and it will work.
If you still have problems, you may need to send your DME to someone.
You need a cable with a genuine FTDI FT232R chip.What cable would you recommend? I am starting to think that is my main issue.
It’s got to be a problem with your car/DME.I tried the one build journal recommended. Getting the same results as I was with other cable.
