So my observations are
There were no M6 washers in the pack like Nicks one (kindly added by Nick)
The Manual needs some work - at one point it tells you to put a M6 bolt into a M5 nut - however as guide its fine and the mistakes are easy to spot.
I have 4 plastic nut caps that are not on the parts list left that I have no idea what they are for.
Fitting to the van needed to be thought about as the manual was no help.
The rack is of very high quality and looks like it will stand the test of time.
The fit is very good and the rack is going nowhere.
Overall I am pleased with my purchase and it represents much better value than the VW oem one which is over twice the price.
If you are in the market for a rack give Nick + comfortz a ring.
