Hey guys,
I’ve had to replace the DME in my 06 E92 323i with N52B25K engine. Have successfully updated all the ZUSB’s and changed the VIN in the DME, however I thought I would be able to extract the ISN and code the CAS module with the software that I have (INPA/ISTA+/P/D/Bimmerlabs suite), however the more and more I research, the more evident it becomes that specialist software/hardware may be required.

Is anyone able to log in remotely to assist me with this process? Im located in Melbourne, Victoria, Australia, if anyone has the proper equipment and can come to my location.

Of course, I am happy to pay any reasonable costs to have this done.

Can anyone help me? Or have I royally screwed myself..?

Im assuming you installed a used DME? If that's the case then I think the only way to get it to work is to send the DME, CAS and key away and have it reprogrammed with your VIN. It's not possible to do it remotely i don't think. The other alternative is to buy a DME, CAS and key set from a wrecked car and install into yours. You would have to do some coding with the other modules in the car though.

You can get the used dme programmed to the car but it cannot be done remotely with any sort of software. You'll need to send out the current dme (if responsive) and used dme for it to be cloned or you can send out used dme, CAS and key fob. The tools required to match ISN cannot be done remotely with kdcan unfortunately. You can also pull the matching CAS unit and key from the car you got the dme from but keep in mind you'll have tamper dot on cluster due to the mismatched mileage and vin between CAS and cluster.

Thanks for the reply guys.
The original DME is fried I think; I don’t have high hopes that it can have anything extracted from it.
I’ve already coded the VIN and VO to the new DME;
To the best of my understanding, I now Just need to extract the ISN from it and write it into the CAS module - can anyone confirm that?

I don’t think it’s possible to get the CAS and Key as I bought the vehicle second hand and it came with this DME, which was not yet plugged in.

Another route ive read is resetting this DME
to ‘Virgin’ state, where it will be able to marry with the EWS/CAS unit, however I haven’t been able to find out any more detailed info.

Two questions:

- has anyone has experience with the Yanhua ACDP machine and it’s functionality? I have the option of buying one with the DME/BSM, ISN and Key coding modules, however I’m not sure if I can use it for my objective without the CAS module?

- does anyone know where I can send my units to have programmed in Melbourne? And any idea how much I should expect to pay?

Sorry for the overloaded response;
I’ve been researching for couple weeks now and my brain is literally spewing BMW programming jargon lol

Need this sorted so I can move on with my life haha

Cloning the MSV70, which I'm guessing is the one you have, is relatively easy.

The above link describes doing it with inexpensive Chinese clones of BDM tools like Alientech's KTAG. These Chinese generally (although not always) work. I've had great success with such tools.

Of course, if your DME is really fried, you might not be able to access the processor using BDM, in which case you are shit out of luck.

Finally, to echo the comments of EvaBMW and sd*********, you are not going to be able to do anything useful in this regard with BMW standard tools and a KDCAN cable.


The Yanhua ACDS systems is nice but beware, it is modular and you have to make sure you purchase enough of the required modules to accomplish what you need to do. It adds up and gets expensive. I'd be delighted to sell you my ACDP mini. Except it would cost more to ship it than it is probably worth.

To directly address a question you raised that I did not answer:

Yes, you could extract the ISN from the new DME and write it to the old CAS. Yanhua ACDP could probably do this for you but I do not have the required module and have not attempted it. Don't expect Yanhua to give you a straightforward answer in English to this question. Or rather, expect them to just say yes to every question you ask. Alternatively, you could extract the ISN from the old CAS and then use a BDM device to write it to your 'new' DME.

There are other ways to write the ISN to the CAS but they are somewhat involved and require a programming device (like R270) as well as the knowledge of how to use it. I don't know of a write-up for that as complete as Hassmaschine's is for BDM cloning the MSV70.

Keep in mind, it is possible that you can still extract the processor's internal flash with BDM even if OBDII communication no longer works. Possible but certainly not guaranteed.

There are two other ways not mentioned.

Bimmerlabs, Hass can do an EWS delete to skip all of this nonsense.

You can also "Virgin ize"the replacement DME and when you install and update the software with Winfkp, the ISN will copy over from the CAS.

Hey guys, thank you for all your response- it’s a great help )

Ok to narrow it down - it is a MSV80, not the 79, which makes things that little more difficult.

‘Virginizing’ the DME sounds like the way to go. Anyone know what is needed, or where in Melbourne I could have it done?

Somebody was selling a YANHUA ADCP with the BSM/DME, ISN, and Key Programmer modules; I was concerned that without the CAS module, I’d be only halfway to my goal.

Can anyone confirm this?

Yes: I too am worried that their customer support will slowly drive me insane ://

Thank you so much everyone

Hey guys,

Just quick update - managed to get the DME coded at a local indy repairs shop and they did a stellar job! Car started first go, was rough as guts, but after slowly working through all the error codes, she's purrring beautifully now.

Only issue is I think the DME software is for an N52 with a 3-stage intake, whereas this car has only the single stage intake. Symptoms are half engine light and rev's being limited to 3k with heavy misfiring. Plugs were changed recently, so I'm guessing it's the software.

Anyone got any ideas?

Can you post the fault codes. If the half engine light is on there must be codes.

you'll need to flash your DME to the proper calibration using WinKFP. Since the VIN is updated, comfort mode should work, but expert mode should work as well.
