Tiptronic service
 

Not a re-post of the how-too as there are already goods ones on the site. After reviewing a couple of them I decided for this 80k Tip service I would try the drain/fill run, drain/fill run, drain/filter/fill final - flush method. Seeing how the first two cycles will burn about 8-10L of fluid I was looking to get the best price I could find on a Pentosin 20L jug. Just thought this might be helpful if anyone else is looking for a deal, this stuff commonly runs in the $15-20L price range. One stipulation, this is an Amazon Prime member price, $203.74 shipped to the door.
