Problem:
Xhorse Multi prog and MQB rh850 cable.
Tried to read R7F701407 dashboard, but can’t connect the dashboard. Removed 4 capacitors according to the diagram correctly.
Multi-prog reported error “Chip configuration failed. Error code: 08030001. check the connection.” Any advice?
The problem is usually caused by wrong correction.
Wrong wiring. directly solder wire to the board point.
Do not extend the length of adapter, otherwise will fail to crack data.
Remove the extension components and directly weld the wire to the point and try again.
