I have done it and there is certainly a section in the service manual that details the sequence. Problem is Indont know where it is exactly. There is a full set of Service Manuals in PDF form for the 2009 model. It's in the files section of a facebook group "Grand Voyager Mk5/Tech Help Group". I think it might be in a section with the name "Body" in it. If you join, answer both questions and the ask there. I will use that as a memory trigger to look at my version of the TechAuthority version - the PDF's are extracted from a version of this.
