Hallo,
i have solved this problem.
The engine has self change the HDD to "faulty part isolation" with software-switch 18 bit 7 to 1.
After HDD-aktivation with SW-switch 2-0 to 1 and 18-7 to 0 appears error C-D0E1.
I replaced the HDD/K and i carry out "Replacement of the Hardisk" from service-manual and that was fine.
Lucky greetings
mr.propper
