Hi Rob - sorry I didnt realise it was your 1st post (i didnt look).
Liqui-Moly is a very good quality oil manufacturer - and I would not have any problems using this brand in my own cars. If the Liqui-Moly DSG specific oil is cheaper than the VW OEM fluid then I would not hesitate in buying it. Note that there are other brands that make a DSG specific oil (Pentosin, Swag, and I believe Penrite also make one....im sure there are also others).
Note that with Penrite being Australian made and owned, it is a cheaper alternative than the European brands while still being a very good quality oil that's synthetic. Note that the Penrite bottle is 4L instead of the more common 5L which also add's to the cheaper price:
