trailer hitch
easy and simple activation on your own
You have retrofitted your trailer coupling and are failing to activate it on the vehicle? Even your authorised workshop or independent workshop you trust cannot technically manage the integration or simply does not offer it?

This is where we come in! Get your personal OBDAPP interface today with which you can easily implement the model-specific activation of the retrofitted towbar yourself.

How does it work? It's simple! Through our diagnostic partner status with VW AG, we ensure that the installed trailer coupling is correctly connected to the vehicle and that the retrofitted trailer control unit is fully integrated into the vehicle electronics.

Our OBDAPP carries out all the necessary steps fully automatically. All you have to do is plug the OBDAPP interface into the OBD port of your vehicle and activate the trailer coupling. Afterwards, nothing more stands in the way of the full use of your trailer coupling! All dependent control units (such as assistance systems, engine, chassis control or parking aid) are configured correctly and correspond to the factory settings.

Any error messages after installation of the trailer coupling without correct activation are therefore a thing of the past and you can move your vehicle safely again!

Procedure for retrofitting trailer hitch summarised:

  1. Install trailer coupling including control unit
  2. Order OBDAPP Interface for your car model
  3. Plug OBDAPP Interface into the OBD port of the vehicle
  4. Connect OBDAPP with OBDAPP Interface
  5. Activate the trailer coupling
  6. DONE!
