Immobiliser

The model Octavia III features the immobiliser of the fifth gener‐
ation with on-line connection and Download. The main compo‐
nent of the fifth generation immobiliser is a central database, in
which all of the theft-relevant data from the participating control
units is stored. It is not possible to adapt the immobiliser control
units without online connection to this database.

temporary activation of the components is not possible.

line.

the factory for a specific vehicle and can only be initialised for
this vehicle.

cation number must be provided.
♦ In Škoda vehicles it is not possible to adapt the components
of other corporate brands.
