Problem:
It’s a 2018 VW Polo MQB48 model with processor R7F701401.
I have the PCJ7991WT chip on the PCB, which finally confirms that it is the mqb49 5c.
Xhorse VVDI2 cannot decode data (read by multi prog) or change the mileage.
Solution:
It’s MQB49 cluster. Requires new MQB49 5C adapter set.
Only use the new MQB49 adapter, vvdi2 will decode data to change 5C/5D cluster mileage.
Use new MQB49 adapter and use this option to read cluster, than decode data with vvdi2.
