I know it sucks. VW didn't even put an inspection interval for this into the service booklet. This is why they switched to the TSI with a roller cam follower mid-year of '08 here in the states...not sure when the TSI came along there. The US gave a warranty extension for this here in the US for 120k miles or 10yrs.
Looks like you need a new cam chain adjuster as well. I would do it all...the new intake cam only, the exhaust cam should be fine...new hpfp and cam follower...and cam adjuster cover only if it looks worn in the cam follower cylinder there where the hpfp mounts to it. You didn't have a pic of the CF cylinder. The inside damage to the adjuster cover, you did show a pic of, shouldn't cause further issues. That is likely done from broken CF bits romping about in there. You'll be sorted for up to another 100k miles, but I would start checking it, or just replace the cam follower, every 80k miles thereafter.
