I have just received my KKL VAG-COM for 409.1 in the post. I have downloaded a trial version of Nissan Datascan II v2.53. For some reason I cannot get v2.53 to find the adaptor.
I can confirm Device manager says the "USB-SERIAL CH340 (COM8) is working properly. In the communication section of v2.53 I set the com port to 08. Nothing!!!!!!

I have methodically used Generic adaptor with DTR (checked or unchecked) while changing the Ini Timer offset from -5 to 5.
I have also done this with the Blaztll adaptor setting (just in case).
I have done this with the adaptor connected to the vehicle and NOT connected to the vehicle.
What gives?????


If this helps the vehicle is a 2010 Nissan Navara 4.0L V6 petrol.
Please help!
Kind regards
