Typical repairs and vulnerabilities in Phaeton life?

In my previous year’s review of my dream ship, which is now 6 years old, my mechanic had announced the necessary exchange of the bearings of the front crossbars. Had the opportunity to take a look at it for a short time today and I could not see anything from porous. Also no noises from the wheel suspension or suspension. Is this a typical weak point which is repaired during this running time of VW in general? I would therefore like to ask the question in the round, what happened to you over the years with typical repairs at the regular services or also otherwise.
