MSV70 must run by anyway, did you check fault codes in DME?
For flashing, it is not the issue here.
But if you insist to flash it, we can let you pass this restriction,
But it will under your risk...
The DME may will be flashed correctly, but if HW is different from what is supposed to be, you may get fault codes that will never be erased.
Contact support if you want to go forward.
