Motor vehicle notification technical change


Certain technical changes must be assessed immediately by the Technical Inspection Centre or an officially recognised inspection organisation (DEKRA, GTÜ, KÜS, TÜV):

  • Change of vehicle type
  • Change of displacement or power
  • Increase of the maximum speed determined by the design
  • Reduction of the maximum speed determined by the design if it is relevant to the licence or if tyres of lower speed classes are to be used
  • Modification of permissible axle loads, maximum weight, payload, fifth wheel, resting or trailer load
  • Increase in vehicle dimensions, except for cars and motorcycles
  • Change in the number of seats, berths or standing places for buses and coaches
  • Changes in exhaust or noise values if they affect vehicle tax or traffic bans

These technical modifications must be entered in the vehicle documents by the competent authority.

Process flow

The vehicle was presented to a technically competent person (e.g. TÜV, DEKRA, GTÜ, KÜS, SAVAG) and the modification was examined. If the change does not have to be entered in the papers, this is noted on the TÜV report.

The application shall be submitted to the competent body in person or by a person authorised in writing.

Who should I contact?

The responsibility lies with the district, with the district-free city and with the municipality, joint municipality and city entrusted with this task.

The main residence according to the identity card is decisive. In the case of legal persons, this is the registered office of the main establishment or the registered office of the branch.

Requirements

  • Vehicle is already registered
  • technical changes have been made
    • e.g. by attaching a towbar, reducing the performance of the motorcycle or similar
