Not aware of any bullitin of a recall on the version 5 disc's (for E etc) and the part number remains unchanged from what I have seen. So not sure what all this is about will have to have a look into this on Monday as this sounds weird.
I do know that the Version 8.0 disc for the Audio 30aps has been delayed due to software integration issues as has the V5.0 disc for the C class, ML, A, B and Smart(the part number originally allocated has been removed as well), but nothing about the comand disc for the E class.
