think you may have the 1.3 cdti in your van,unclip collant reservoir,swing to front,remove two 13mm nuts holding fuel filter to bulkhead and swing over onto engine,disconnect battery,look down on top of bellhousing for an oval grommet and remove,in there is the top bolt for the starter,torx 50,dont drop this bolt or a socket in there or it is a g/box out job,jack up and support with stands and remove the lower torx 50 bolt and wiring connections on starter and remove,refit in reverse,usually have one person up top for the top bolt and one down below for the starter,good luck
