Xhorse VVDI MLB Tool Data Calculation Failed Solution

 Problem:

One of our customers tried to add a spare key to Audi Q7 2020 with the Xhorse VVDI MLB Tool. However the tool failed to collect key data.

Error “Key data calculation failed”.

Common Issues with Collection Failures

• VCC1 and VCC2 are reversed.
• The capacitors were removed incorrectly or not removed.
• Short circuit in soldering.
• Data collection requires wireless reading of the key simultaneously; if the key is not positioned correctly, it will not be detected.

Check the above and collect key data again.
