I know this post is old but I had the same problem.
The solution is to reset the electronics / upload new software to the computer module (the one under the passenger seat behind the driver) or replace it with a used / new module with installed amendments.
You can do the reset yourself at home:
1. with the engine off, find and remove fuse no. 20 in the electrical box under the hood (the one described as FDCM EDIFF);
2. start the car and drive about 5 m forward and then 5 m back, turn the car off;
3. put the fuse back in its place.
after this procedure, the error in my car disappeared and it was possible to restart the Quadradrive II.
Maybe it will help someone.
Kisses,
