We answer in English and German, normally within two working days.

There is no telephone support. Everything about an installation is handled in writing, because it usually needs the app to send us what it saw.

What this site is

A description of Casto Flasher, an application for owners of BMW cars. Nothing is sold on this site. Purchases happen inside the app, on the car they are for.

Online dispute resolution

The European Commission provides a platform for online dispute resolution at ec.europa.eu/consumers/odr. We are not obliged to take part in dispute resolution proceedings before a consumer arbitration board, and we do not do so.
