Any advise please?,It worked fine for the first 2-3 times.

A: Reprogram it, you need Reflash the china vag com

When vag com have any question, you must program Atmega162 with an external programmer
After that you need to program FTDI over USB with Mprog
For RL cable you must program GAL/ATF - I assume that you have a RL cable because you asked loader
and for RL cable you need to do some modifications to the PCB

then install VCDS 11.11.0 and copy loader to installation folder

Make a shortcut to your desktop (loader)

every time you want to use VCDS -- click the shortcut on the desktop
