You might not all be aware but the oil feed line for the chargers has recently gone obsolete! :|
They're a set length and diameter to keep the flow and pressure at the charger right, if these are changed it effects both these factors and damages the bearings or reduces their life quite easily! This has been found when people have tried to make their own feed line.
Luckily I've managed to secure a source of the genuine lines from the company that supplied direct to VW
Here's a link to them on my site, they come with new banjos and washer as standard
