Your indy mechanic was obviously not a BMW Specialist. If he presented himself as such, then he is delusional.

So to update the 2F44 and 2F45 codes (the ones that seem to have been holding my car hostage) have gone and have been replaced by a 2B71 which ik has to do with the disa valve.
Will report back if the problem returns, thank you all for the help

The thing is, the dude did. when I went up there to drop the car off he was telling me that he's been working on euro cars for years and that he's seen this problem many of times before. I should have known something was up when I saw the 20+ BMWs sitting around outside.

Merry Christmas All!
So, I'm in a similar boat to 3X3Tails. I purchased a 2006 E60, production 9/2005, with a replacement key from a locksmith. The seller had the key made because they didn't have any others. The locksmith's key started the car 1x for her and then went CRANK NO START. My suspicion is the locksmith knew how to force a one-time sync to start the car. Afterwards the sync went off and the 2F45 immobilized the car.

I purchased a new, official key from BMW. The Key from BMW is set as key #4

My experience is very similar to 3X3Tails. I have 2F45 error code. I'm able to identify the ecus in the car. DME shows at 12 and CAS shows at 40 in the list. Each indicate they are "OKAY". I mention this because cable functionality is a consideration for what my problem is.

I've tried INPA > E60 > Engine > N52 > SHIFT F6 [sync cas dme] > F1 [program] or F2 [reset] after a moment IFH-0009 API Error #9 No Response From Control Unit.
1. Is the cable bad? (in tool32 I'm able to open cas.prg and msv70.prg and each provide a long list of jobs to run on them).
2. Is the control unit that is not responding the CAS or the DME or both?

When I try INPA > E60 > Car Access System [I presume this is CAS] > Activations > Sync CAS DME > I get:
VIN unknown
CAS black dot
DME black dot
Whatever the 3rd one is black dot
(if I try to print this - it hangs)

3x3Tails - did your VIN appear here?

As an aside (or diagnostic clue) - when I do
INPA > E60 > Engine > N52 > SHIFT F7 [Start Value Comparison] > F1 or F2

CAS-Start VALVE comparison MSV70

CAS Start Value = Okay

Request to control module to compare start value = Reset DME and CAS to start value

Response from DME = DME bereit Startwert zu empfangen (translation DME ready to receive start value)

Waiting time of 2 s

Receive status = Prozess laueft (translation Process is running)

Is it the case that this needs to run for some extended period of time? How long does it take for "Process running" to complete?

Any guidance or advice would be very much appreciated.

Thanks for reading.

I would love to tell you but this was a while ago and it happened really quickly, I just hit the button to see what it did and it had popups that turned green and with no real explanation of wtf it was doing. Tbh I feel like I got really lucky with the car starting after that because I still don't know what that thing really did. I would go and see if my cars vin shows up but the bat is dead and I don't have a real reason to charge it back up till I can properly diagnose the issues its having now. Sorry I can't give you a good answer.

If memory serves me right there should be somewhere in inpa that you can see info on the car, surly somewhere is the vin of the car and if not there might be somewhere to put it in if its missing.

Thanks very much for answering. I see the VIN Everywhere else, I just don't see it in the
Initiate Start Value Sync with Motor ECU
F4 E60 > Body > Car Access System > Activate > Sync Motor ECU

The sequence progresses indicating communication between INPA and the modules with each step.
Write start value goes from white to black. Reset CAS & Prepare DME remains white.
Reset CAS goes from white to black. Prepare DME remains white
Prepare DME goes from white to black
One dot, two dots, three dots. . . then it hangs. "

Similarly - when I do F4 E60 > Motor N52 > SHIFT F6 DME EWS SYNC > Program F1 or Reset F2
EWS-STARTWERTABGLEICH (EWS Start Value Reset / Sync)
I get IFH-0009 NO RESPONSE FROM CONTROL UNIT
(status message changes from RUNNING to STOPPED)
The next screen says WECHSELCODE_SYNC_DME with a caution icon. It clearly does not complete its function.

This gives me some indication that WECHSELCODE_SYNC_DME can be performed in tool32 but I have some confusion about which .prg to use for this. I think it's EWS.prg but my Ident in INPA doesn't show EWS as a module (I think it's being managed by the CAS Module.) However, CAS.prg doesn't shows this job.

From previous reading I think there may be a sequence of jobs to perform in tool32. Wechselcode_Sync_DME in EWS.prg and then some job in MSV70.prg but with an argument of 0x01 entered?

Finally, can anyone tell me if there is a strict procedure for how these steps should be taken? Key In, Relay 15, Remove Key, let car sleep, battery voltage, time to let a process run? Any of these or combination of them?

I attached a PDF of all my modules

Thanks for reading and Merry Christmas!

First off, forgot to say but, Merry Christmas to you and to all who are lurking about! Hope the holidays treat you all well.

Now seeing your screen with the 3 black dots and i.o. labels looks very similar to the screen that I saw. Not exactly like mine but that could be because I used bimmer geeks version of inpa which is a bit rough around the edges. I don't remember what exactly happened as it really did all happen in the blink of an eye. Idk if that's how it normally happens or if it was because my laptop has decent specs, but whatever the reason it did the alignment really quick. From what I can tell your using the same function that I did that day so I don't really see why it's not working. All i can really do is give some maybe not-so-crackpot theories as to why its not working. Now I'm absolutely not an expert so take what I say with a grain of salt, maybe not even that much.

The first one is your laptop might not be up to snuff for this job. Don't quote me on this but i remember someone on one of the bmw forums talking about how inpa is picky on what systems it runs on but, I assume this laptop has been used with inpa on your 750Li so perhaps it was fine with working on the that car but is having a fit over doing work for the 525i. Now that was a while ago that i was doing this research myself and I might be misremembering but if you have a extra laptop lying around it might not hurt to try installing inpa on that and seeing if the issue persists through laptops.
The second one is that the install might be borked. That was asked of me when I was going through this issue so by extension your being asked too. Did you install inpa correctly? Perhaps try uninstalling and reinstalling incase inpa did mess its self up. you could also try a different source for the install of inpa, I went from bimmer geeks to some other source back to bimmer geeks before I figured it out. once again, worth a shot right?

Those are the only two that I can come up with atm.
Some things you might want to think about are stuff like is the key being recognized, the key position is in accessory, the cable on the right setting, the battery have a good charge stuff like that.

While all that might not lead you to a solution I can give you one real piece of advice, trying that set start value function in the engine isn't going to work and, until you realign the cas/dme, will always give error #19. Error #19 was like my arch nemesis in trying to fix my car. I'm pretty sure the cas/dme have some functions on lockdown like setting that start value and will just ignore it. Maybe the reason why maybe not but it is for sure not what your looking for.

Once again, sorry I can't give you a straight up answer. This is the best I can do for ya. If this leads to no where then I suggest looking into other codes your car may have and see if the are hindering you in getting it running. My 2f45 was paired with a 2f44, if you have them aswell then its for sure a cas/dme misalignment.
If that all turns up empty then make a new forum post because there is something else going on that is outside the scope of this one.
However if you do get more info on it or get it sorted then make another reply back here, I'm sure it will be useful to the next unlucky soul that has the same issues. (hell I'd like to hear how you fixed it)

Good luck stranger, hope to hear some good news!

I have the exact same problem in my car and finally after replacing everything under the sun took it to a professional LOL and found out that my computer had a bad ground which caused it to go bad it kind of fried one side of the board so I was getting all these codes nothing was really wrong with cars the main computer they got a bad ground so check your ground to your computer have it tested and if it's bad hopefully it's not too bad that they can still clone it it's a lot cheaper that way but anyway I had the same problem that you had replaced my computer with a cloned one and issue went away cars been running great ever since no codes

When I go to the car ill get a video of the dash with both keys.

It has a 3 position switch with 2 wires connected to it. I've tried it on all three positions to no avail. A friend is willing to let me borrow his cable soon so I'll try with his if it doesn't get resolved by then.[/QUOTE]
