Hi,

My VCDS is having a problem when doing the Auto Scan, it is for any car but I can sample for Q7, 2012, as attached. I have tested the device to the car successfully and also test different car, once I keep doing it for 5-10 times auto scan for the same vehicle then sometime it goes through and work. My USB connection is firm and no one touch it when Autoscan.

Manual scan is no problem.

Error 99 is suggesting the communication between the PC and interface is failing. You say you're keeping everything perfectly still when performing the scan; but it could be any of the following:

USB Drivers, are you using the latest packaged with VCDS?
USB Port time-out. What Windows version are you using; when installing VCDS, did you check the USB port powersave option?
Poor connection between PC USB port and USB plug.
Poor connection in the USB lead.
Poor connection of the USB lead in the VCDS interface.

If you have access to another PC, you may try that, but hopefully the above will help us get you a little further. :)
