Remedy
Important note:
In light of this, we would like to point out that third-party electrical installations/electrical retrofitting operations in the
vehicle can significantly contribute to faults.
The vehicle must always be checked in its standard condition.
The current global shortage of semiconductors has resulted in a delay in the production of the new hardware.
Remedy of new hardware for radio/radio - navigation (RD) control unit (N87/15) is expected to be available in
Q4/2022.
