(25)To prevent anti-tampering measures from unduly hampering competition, this Regulation should maintain the possibility of allowing independent operators to develop, distribute, install and activate aftermarket replacement parts. Therefore, manufacturers should not deny independent operators access to the information, tools and processes that are strictly necessary for the development and installation of such replacement parts. Approval and authorisation of independent operators to access vehicle security features should be granted in accordance with Regulation (EU) 2018/858.
