If you try to enable “Developer mode” on the VW Discover Pro navigation with VCDS you will get the following error: “Request out of range:”

VCDS | Discover Pro | Adaptation | Developer Mode | Request out of range

This happens because VCDS uses a type 0x02 (Programming) session but this adaptation needs type 0x4F (Developer) session.

Ross-Tech has just released a new Beta Version 16.5.0 that enables a switch to Developer session.
