VCDS - Windows Based VAG/VAS Emulator Running on Windows 10 圆4 PS The blown headlamp bulb has been replaced and the error code deleted so there are now no outstanding faults.

Please can anyone help me with accessing the missing control modules, A1-Navi / 37-Navigation in particular? Perhaps some LT3 models are different to others?

I understand from web searching that some user seem to have had success using VCDS to access the Navigation unit on an LT3 van but how this was achieved is never explained. When I did the first scan there were half a dozen ROD files not found but Andy kindly sorted this out for me and now there is only one, CRFT2_ESP 3 which is not found, but I am guessing that is nothing to do with A1-Navi. I cannot access Radio or Navigation under the Common tab either. The engine and gearbox are VW but I understand that all the other components are Mercedes and VCDS can access many of these but not the one I want to complete a rear camera install which is A1-Navi.Ī0-Radio is not accessible either although the radio sound does mute and produce various bleeps during the scan so VCDS does appear to be accessing the Radio/Nav unit but then not producing any scan information.

All the other accessible modules are under the LT3 tab. The engine cannot be accessed through the LT3 tab using 91-Engine but can be accessed through the Common tab as 01-Engine. I can select LT3 from the drop-down and perform an auto-scan as below and the modules which are scanned are 01-Engine, 93-LT3 Immo, 94-LT3 Airbag etc as shown in the scan.
