The
guide is correct,
Just had exactly the same
problem last week, fetched about 3 litres of water out the carpet and wadding of the rear drivers side of my 2004 LCR, re patched the door seal with VW cord and all is now good (Fingers Crossed). No water on my sill anymore either.
One tip is get the rear seats out and pull the carpet forward as much as possible, the water gets everywhere, took a good hour the get rid of the main bulk of it all.
