Xhorse Vvdi Prog Mqb 3532 Cluster Frequency Error 3

Xhorse Vvdi Prog Mqb 3532 Cluster Frequency Error 4

Xhorse Vvdi Prog Mqb 3532 Cluster Frequency Error 1

Xhorse Vvdi Prog Mqb 3532 Cluster Frequency Error 2

Possible solution:

Don’t connect adapter to cluster, only connect MQB adapter with vvdi prog, with 12V in both VVDI Prog and MQB Adapter.

If only has frequency failed error, you have to measure FLMD0 voltage.

Go and read by TEST_OPTION_15,  measure the FLMD0 voltage, normally the FLMD0 should be 3.3V, otherwise, the vvdi prog is faulty. Need to send back for repair. Xhorse Vvdi Prog Mqb 3532 Cluster Frequency Error 5

Test Mqb Adapter Voltage 1 Test Mqb Adapter Voltage 2 Test Mqb Adapter Voltage 3

Here is the customer solution, supply 3.3v to FMLDO on adapter. He tested all good read and write No problem.

If don’t know to send back adapter or prog to repair, try supply 3.3 to FMLDO.
