Today I tried to update a S8 D2 with retrofit Euro RNS-E. The update CD I normally use produced a load error, CD unreadable. But the Euro map DVD I have works fine.
Checking the car with VAG-COM I saw that the BNS the car came with was still connected and answering on #37. I was able to connect with VAG-COM to the RNS-E via #56 but I'm not sure if having both connected would cause issues reading CDs. I read a couple of times that either CDs are readable and DVDs aren't or vice versa but I don't know if those issues are related or not.
We didn't troubleshoot much further but I was wondering if anybody here came across the same issue before.
