Point in time view as at 30/05/2018.
Regulation (EU) 2018/858 of the European Parliament and of the Council, ANNEX X is up to date with all changes known to be in force on or before 02 December 2024. There are changes that may be brought into force at a future date. Changes that have been made appear in the content and are referenced with annotations.
Changes and effects yet to be applied by the editorial team are only applicable when viewing the latest version or prospective version of legislation. They are therefore not accessible when viewing legislation as at a specific point in time. To view the ‘Changes to Legislation’ information for this provision return to the latest version view using the options provided in the ‘What Version’ box above.

A manufacturer, including a final manufacturer, shall not charge fees for providing information relating to the website address or contact details of any other manufacturer.
For the servicing and reprogramming of the electronic control units relating to the customer adaptation, the manufacturer shall make the respective proprietary specialist diagnostic tool or test equipment available to independent operators as provided to authorised repairers.
The customer adaptations shall be listed on the manufacturer's repair and maintenance information website and mentioned in the certificate on access to vehicle OBD information and vehicle repair and maintenance information at the time of type-approval.
Those customer adaptations and any electronic control unit related to them shall also be listed on the manufacturer's repair and maintenance information website.

Information on all parts of the vehicle, with which the vehicle, as identified by the VIN and any additional criteria such as wheelbase, engine output, trim level or options, is equipped by the vehicle manufacturer and that can be replaced by spare parts offered by the vehicle manufacturer to its authorised repairers or dealers or third parties by means of reference to original equipment (OE) parts number, shall be made available, in the form of machine readable and electronically processable datasets, in a database that is easily accessible to independent operators.
This database shall comprise the VIN, OE parts numbers, OE naming of the parts, validity attributes (valid-from and valid-to dates), fitting attributes and, where applicable, structuring characteristics.
The information on the database shall be updated regularly. If this information is available to authorised dealers, the updates shall include in particular all modifications to individual vehicles after their production.
data shall be exchanged ensuring confidentiality, integrity and protection against replay;
