The test in the Crossfire showed that the gelonte Skreem module doesn't work like the original. You can open and close the car with the key, but the immobiliser doesn't work.
The PCM has saved the following error:




This is what the original Skreem reports:




And so the clone:



Identical.

And also the other parameters were identical:








The only difference I could find was the VIN stored on the modules.
Original:



Clone:



This must also be stored somewhere on the processor. When repairing Uwe's Skreems, I simply soldered the processor from the Crossfire to a module from the SLK, so all relevant information must be on the processor.

Since I have no idea how to change the VIN in the processor I declare the project Skreem Cloning to failed.
