Free download the FIX enables the access to diagnosis of vehicle types W204 (C, GLK Class), W207, W212 (E Class) via DAS standalone menu, without XENTRY. Very convenient.
32bit Windows only, not 64bit
Note: it’s free, but not tested by professionals!!!!!!! unknown security and perhaps high risk sometimes!!!
