Solution:

You can restore it with ACDP itself.

If does not work error "Restoring Coding data failed, please use BMW ESYS to restore the Coding data”, follow the suggestion and restore data withE-sys.

 

User report:

1). Restored (remotely) with esys and added key on bench.

2).

I had the same issue with a BDC in two different occasions.
I ended up restoring data with Vvdi bim tool.
