Vehicle registration certificate: Change vehicle data (technical change) Unfortunately this specification of service has not yet been completely translated.

Your vehicle is already registered and has been technically modified, e..B by attaching a towbar, reducing the performance of the motorcycle or the like. A technical change also exists if the vehicle is to be re-described because it meets a higher emission standard since the date of the first registration following a manufacturer's certificate to be submitted than is recorded in the current registration documents. Certain technical changes must be examined immediately by the Technical Testing Centre: Change in vehicle type Change in displacement or power Increase in the maximum speed determined by the design Reduction of the maximum speed determined by the design if it is relevant for driving licences or if tyres of lower speed classes are to be used Changes in permissible axle loads, total weight, load, saddle, towing or towed load Increase in vehicle dimensions, except for passenger cars and motorcycles Change in the number of seats, seats or standing places for buses and coaches Changes in exhaust or noise levels, provided that they affect vehicle tax or traffic bans If the change does not have to be entered in the vehicle documents, this is indicated on the corresponding part approval. Technical amendments must be entered by the registration authority in the vehicle documents in a number of cases (such as .B. the reclassification of a vehicle). If the emission standard is improved, the improvement will only have an impact on the vehicle tax to be paid when the vehicle documents are entered. TIP: Before converting or rebuilding, ask an officially recognized expert for motor vehicle traffic or a test engineer of a monitoring organisation whether the operating licence is impaired or whether the modification is eligible for approval at all. Conditions: Where an entry in the vehicle documents is required, the vehicle shall be demonstrated by an officially recognised expert confirming the proper entry, assembly or disassembly by means of an expert opinion. Procedure: The application must be submitted to the licensing authority in person or by a representative authorised in writing.
