You can access it by removing the Vanos and the exhaust hub.
Mine was totally frazzed at about 120k miles.

Yes - mine was on the tipping point of failure when "Kaiv" helped me worked on the Vanos a couple of years ago (when the car only had ~46K miles on it)! So that looks to be a 50K-mile wear item as well.
Looks like Beisan have an improve upper chain guide now =>
