As for the codes, why do they show inactive, yet I still can't do anything with the car?

Prog zb update the dme and default code it in ncs expert, that should get rid of the incorrect coding code

I'll try that again, but the problem is that it won't turn the ignition fully on to allow the DME to update. I was only able to do that with the mismatched CAS.

Edit- tried to sync once again, same problem. It freezes like this.

has the harness been altered in any way? like for the MSV80 swap it had?

An alternative would be to just delete EWS and be done with it..

[bmdubya1198]

The harness has not been altered as far as I can tell. I noticed this relay missing on the main junction box... not used in my car or is there actually something missing? The fuse guide just shows an engine.
Meant to mark it up, but the relay socket on the bottom right just below that black relay.

Then, I checked near the DME. This relay wasn't clipped into place, but it's installed in its connector correctly. No, it wasn't left like that, I pulled it out the rest of the way.
Everything else looks fine, checked the fuses and they're all good. However this fuse block looks odd. There are supposed to be 4 fuses according to ISTA and newTIS, yet there are 5 on my car. All 30 amps.

Is it possible that there's a problem with the steering lock? Resetting the ELV counter several times has done nothing, and this is what my dash looks like when I insert the key fob. Pressing the start button just turns it off, then if I press it again, the lights come back on just like this. I can turn on the odometer by scrolling through the options, and the radio/windows work since it's in the "accessory" position.

The steering lock will not let the car start. Try resetting it via ista if tool32 isn't working. If it's CAS3 you can also flash it with ZB that doesn't have EL

It's CAS 2. Maybe that explains why the CAS 3 that matches the old MSV80 DME lets me crank the engine, yet this one won't let me do anything.
Already tried ISTA and tool32 to reset the ELV, neither do anything more than turn the accessory power off and back on.

If you can get to your steering rack, unplug and plug the ELV back in. Might be faulty too. Did you already try factory coding CAS and DME like I mentioned? You shouldn't be getting incorrect coding errors if you did, so I'm not sure if you're doing it correctly.

You could get an ELV emulator if that's the problem.

I used this procedure: https://www.e90post.com/forums/showp...88&postcount=5

Due to the DME not coming on, it won't communicate with it to allow me to factory code it. I am able to do so with the CAS 3 module installed, but not the correct CAS 2.
The odd part is that I can get codes in INPA for the DME, yet I can't code it.

At this point, I hope it's that simple. Now that I've been thinking about it, it makes a lot of sense that the ELV is the problem.
The more I read into it, the more sense it makes that this is an ELV issue. Maybe the PO tried to bypass it with the CAS 3/MSV80 combo as a cheap fix? Who knows... either way, someone screwed up by cheaping out.

[hassmaschine]

yeah that sounds right. This happened in our E91, only I was in Canada and stuck at an airport - we came back from 2 weeks in Mexico, the car wouldn't boot up at all, had the ELV indicator on the dash like that. Towed to a dealer, they swapped out the whole steering column (which have no ELV if I remember right) for me in a couple hours so I could go home (it wasn't cheap, but it wasn't that bad with the exchange rate, plus they cut me slack on parts/labor).

[bmdubya1198]

Usually it seems these cars throw the red ELV indicator when it fails in that manner, but I guess it could go either way.
This steering lock has not engaged since I bought the car, so I'll definitely be looking into that today. It's probably bad.

[bmdubya1198]

Well then... I think I found the problem. For some reason, somebody cut the wiring to the steering lock.
Off to the junkyard to clip a pig tail and order an emulator!

Sure enough, it appears someone replaced the steering column with the newer style without the lock (no connector on mine), cut off the pig tail, and thought the MSV80/CAS 3 combo would eliminate the problem. Didn't quite work...

I'm pretty confident this will do the trick, I'll update everyone once the emulator arrives. Thank you to everyone who has stuck with me!

[bmdubya1198]

The emulator did it! As soon as I connected it, I was able to turn the ignition on. I flashed the RSA delete and the Bimmerlabs software and now the car runs. Still has some codes, but I'll start separate threads for those.

Am I able to change the VIN to the correct one on these two modules?
