Important notice:
The installation of electronic addons for tuning leads in Germany to a loss of the general vehicle approval, if the installation will not be checked and approved immediately by an official authorized expert. Driving a vehicle on public roads without a general vehicle approval might void your vehicles liability insurance and you may loose the complete vehicle insurance protection (please check upfront with the vehicle insurance provider). Driving a vehicle without having a valid vehicle liability insurance is a criminal offence in Germany! Installation of tuning addons may also lead to loss of any warranty claims against the manufacturer or seller of the vehicle.
