ordered service kit which included pictorial instructions. I know that they have to be accessible for all languages but some of the pictures were not fully self explanatory. For example, service kit included sand paper with no explanation of what it was for. Had to ring Helpdesk for assistance as I couldn\'t get the solar powered sunroof to work after I had serviced it. ( this was entirely user error on my part and nothing to do with the service kit) and the response was quick and very helpful. Not the first time I have had to ring the Helpdesk but with the same helpful knowledgeable and successful outcome.Thank you!
