I have copies of the following :
Q Konkret - general requirements - Sept 1998
Q Konkret - new parts integral - April 2003
Q Konkret - capability assessment of suppliers - Feb 2005
I don't know if that are the latest versions. I have no access to the VW portal.
I cannot send them because they are copyrighted manuals.
If you have access, you must find them on :

Best regards,
