Audi SQ5 FL 2022 add spare key successfully with Xhorse VVDI Key Tool Plus and VVDI MLB Tool.
Tool used:
Xhorse key tool plus
VVDI MLB Tool
Xhorse XSMA41EN MLB Smart Remote Key was used as a new empty spare key.
Xhorse Dolphin II XP-005L was used for cutting the emergency blade.
Removed 2 caps (using YIHUA 938D SMD Soldering Tweezers), soldered 3 MLB Tool wires (no solder-free adapter), acquired data and soldered the 2 caps back (under the microscope).
Learned both keys OK.
