Note: I don't have a Volkswagen but I can offer some suggestions
have you read the readme on the node's GitHub page?
Did you look at the simple example flow the node provides? (in the editor top fight, click the hamburger menu and select 'Import'
then click on the 'example' and scroll down till you see the new. Click the arrowto find the sample flow.
Hope that helps and that is the extent of the help I can offer.
