changed mine
I changed my oil a few weeks back,
Somewhat of a pain, took me 2 hrs as I was "feeling" my way through.
The one pain is the protective pan that has to be removed, many screws and bolts.
The oil cartridge can be drained w/o the "special tool" but I was a bit concerned as there is a plastic device (spring loaded) that has to be delt with.
Beyond those two items the process is standard fare.
It cost 14.00 for the filter and 5 qts cost $6.50 each. So at ~46.00 for the materials. ~60 to 80 is not so bad.
Still enjoy the process and will no doubt do it again.
Search on VW Vortex and you will find a pretty good DIY, on a passat I believe, but close enough!
just a couple of pennies worth from me!
