This would ordinarily be true for obvious security reasons.

First off check what version EWS you have to see if you have rolling code ISN but I think you probably do.
There is indeed a way to hack the DME and change one of the EPROM values to think the EWS is accessible thus accepting the EWS and associated ISN within your immobilizer. This value effectively allows for the DME to be "Open" to input. A closely guarded secret, but known to people who possess certain tools & applications.

I have purchased a Siemens DME which comes with the new tune and the above mentioned open value which will accept my existing EWS information.
