Hello, We are getting same issue, Driver Packages are not getting downloaded from Peer cache source devices. When OSDContentDownload.exe inside WinPE client is making request to MP for available download locations, its replying DP locations only in contentreply response, it doesn't contain Peer Cache Source machine, Package is downloaded from SCCM DP location, even though peer cache information is present in SCCM DP for driver package. If we directly reference the same package in Run command line, then its able to identify the Peer cache location.
I'm having the same problem here, I've just realized it, i'm trying to figure out what could be done for that, everything else works with peercache except that part and its a pain. :(
