How in the b'jeezer do you get the washer jets out? I've got a MkII Sharan and the washer jets are block, I just need to get them out and back flush.. no problems there then?? I just cant fathom how you get to them as they are encased in the plastic scutle than seem s to lie behingf the wiper balde arms. Is the only way to get to the jets to take the wiper blades off and then remove the pastic scutle?
