Hi,
Trying to adapt a used DDE (hereafter donor-DDE) to a BMW 320d E90 buildmonth/year; 09/2007.
original-DDE: 0 281 014 238 // DDE 7 809 000 // 08-01-10
donor-DDE: 0 281 014 238 // DDE 7 809 000 // 07-09-16
Tried to write the ISN of the original-DDE to the donor-DDE. This didn't work. After that I changed the ISN of the CAS to that of the donor-DDE and aligned the DDE and CAS whereafter I could start the car.
Unfortunately since installing the donor-DDE I have the following faults:
[HEATING AND A/C CONTROL (IHK) (ihka87) 1 fault]
E72E Message (status of Automatic Start/Stop function, 0x308) faulty, receiver IHKA, transmitter DME-DDE
[INSTRUMENT CLUSTER (INSTR) (komb87) 2 Faults]
A3AF Message (nominal road speed value, 0x200) faulty, receiver KOMBI, transmitter DME-DDE
A562 Message (status of Automatic Start/Stop function, 0x308) faulty, receiver KOMBI, transmitter DME-DDE
[DIGITAL MOTOR/DIESEL ELECTRONICS (DME/DDE) (d71n47a0) 2 Faults]
4BD7 Engine mount, activation
4B4D Message (torque request, active steering, 0xB1) faulty, receiver DDE, transmitter Active Steering
I compared the "coding" of the original-DDE and the donor-DDE. These are the same, however there is one difference, in the donor-DDE the option "Increase engine idle speed to prevent clutch judder" is not available.
Unfortunately AutoHex II is not able to update the software of the DDE. For both the orignal and the donor-DDE it says:
BMW Nr: 7809000
Assem Nr: 7809202
Action: Replace 8512712
When I click continue AutoHex II says that it is not possible to program the DDE.
Has anyone experience with a comparable case? In my opinion it seems that the software on the donor-DDE differs from the software in the original-DDE but I am not sure if that could be the case. Next to that does anyone know why it is not possible to update the software in the DDE via "Indiv Programming"?
Best regards,
Asim
