to be honest im quite a competent diy mechanic. Ive done a lot more complicated things than refilling a gearbox. For the price of the vag tool and the oil it would of been just as cheap to send it into the dealers at £180, but now finding out the box can be refilled from the top its just like any other gearbox oil service.
your mad
its nothing like just refilling a gearbox, that oil is What makes that box function....not just a lubricating fluid.
you need vcds too check the oil level in the box and thats before and after its been filled up with s special tool and in a way someone knows. I used to work for vw so I know how vital it is that its done right.
I can change clutches, cam belts, wheel bearings...all sorts but I wouldn't touch that box. if it goes wrong your 3k down for the sake of 150!
just get vw to do it...least then you have sone form of warranty.
even a specialist who has the kit and knowledge...im not saying you don't but you wouldn't post this if you were fully sure.
im not digging...simply trying too help a fellow member out
ps sorry for grammar im on my phone!
