Do you need TÜV registration ? To comply with Section 19 Para. 3 StVZO, your vehicle must undergo evaluation by an officially recognized expert, technical testing center, or testing engineer.

A valid Quality Management (QM) system and E-approval for optimization modules, are prerequisites for obtaining a TÜV parts report or part type approval / ABE. H.&N. Electronics GmbH holds a QM system recognized by the German Federal Motor Transport Authority (KBA-ZM-A 00011-15), and all Diesel Power® and MultiMotion® optimization modules offered, have E1 approval
(E110R06/029979* 00), recognized in all United Nations countries.

With an E-approval, optimization modules can be installed in motor vehicles, as an "electronic subassembly".

The TÜV parts report or part type approval / ABE, provides information on exhaust behavior, performance, noise emissions, and top speed.

H.&N. Electronics GmbH possesses over 600 TÜV parts certificates, for more than 3000 vehicle types. However, providing TÜV parts reports for all vehicles, compatible with our optimization modules, may not be feasible.

As of January 1st, 2022, the TÜV parts report has been replaced by a part type approval / ABE requirement. The testing scope and documentation requirements for engines compliant, with Euro 6d ISC-FCM (Euro 6d Full) and Euro 7 "Ready" emissions standards, have expanded significantly, making obtaining a part type approval / ABE, economically feasible only in specific cases
(refer to traffic bulletin issue 8 – 2021, pages 409 – 415).  

In the future, these measurements will be carried out according to the new WLTP measuring procedure (Worldwide Harmonized Light-Duty Vehicles Test Procedure) with the associated WLTC cycle (Worldwide Harmonized Light-Duty Vehicles Test Cycle).

In addition, the vehicles' exhaust gas purification systems are tested under real environmental conditions during additional road trips, so-called RDE tests (Real Drive Emission Tests).
The RDE legal regulation does not replace the WLTP, but supplements and reviews it. This makes the measurement of pollutant emissions even more precise and manipulation is almost impossible.
