I have a problem with the DSC ecu of an 2004 BMW E87.
I bought an used 2005 E90 DSC ecu and tried to program it to the car.
ISTA P is asking for replacement.
Is there a way to reprogram the ecu or I have to find one with exactly the same part number?
Thanks!

did you exchanged vin number before using ISTA-P
if not then change to either 0000000 or your vin number and then to coding/programing

I flashed it with winkfp, so the VIN is in it, but NCSEXPERT refuses to code it and ISTA P wants it replaced.
Is there any method to force flash another ZUSB number?
Current number is 6778164 and I need 6769845.
Is it safe to do so?

try coding it to "default"

That's what I did when I got the error in the picture number 4.

***lagunasec*** · 06-05-2017, 18:43 PM,

Any new ideas? What are my options?

Yes, WinKFP expert mode can be used to flash arbitrary ZB numbers.

Most likely ZB number 6769845 will not work.

Why did u flashed 6778164 05/05/17 if you need 6769845?? I don't understand you

Yes, WinKFP expert mode can be used to flash arbitrary ZB numbers.

Most likely ZB number 6769845 will not work.

So, my only solution is to find a DSC with the same ZB number as the broken DSC.

Make Sure u got The right vin in Module. Check with tool32 an rewrite vin Then try again to code The DSC with ncs
