A simple repair brings the device back to its original state, but hardware modifications make it much more reliable.

If you're experiencing issues with your VCDS 22.3.1 HEX V2 clone, there are several repair options available:

Connect the cable to your PC (do not connect to the car yet).

Sometimes, your cable needs physical repair. Here’s what to look for.
