Danke Schon!!! Keep 'em coming!
I'm set with the 14mm allen-head socket, so no worries there. I'll pull on the fill-plug a bit a see if some penetrating oil might be in order...
Also Haasman, this 'plunger' you mention - is that to help with the refilling of fluid or actually removing the fill-plug?
Again - big thanks to all- love this forum!
