If you have received a factory update from your manufacturer's workshop (intentionally or unintentionally), then for SKN it is a reprogramming of the vehicle when the SKN tuning software is reinstalled. Unfortunately, this reprogramming cannot be carried out free of charge, since the workload corresponds to NEW programming of a completely NEW vehicle.
