528 Vanos seals DIY?
So in the next month or so I will be tackling replacement of the vanos seals. Has anyone done this themselves? I'm pretty mechanically inclined and have access so any of the tools i need, I was just wondering if this was a smart move or should I just take it into a shop? Any other advice on the matter is greatly appreciated (things to look for, other parts to replace etc.) If anyone with experience is willing to help out I'd greatly appreciate it, obviously beer and dinner is on me.
