Xhorse VVDI MB W212 Renew ISM Timeout Error Solution

 Problem:

I am trying to virgin a Mercedes Benz w212 2014 ISM with Xhorse VVDI MB Tool but when i try to read it i get “Start transfer/receive data……. time out” and it doesn’t read gets stuck at 5%. This is the second ISM with the same error.

This is my setup and cable i am using.

I am supplying the unit with 12 volt supply.

Solution:

Some W212 can be FBS4 system. Last FBS 3 are 1852

DSM may be the FBS4 system. vvdi mb/any tool won’t recognize FBS4.

The only solution is to disassemble and copy the Motorola.

It will be able to renew d file if you can read the Motorola with xhorse vvdi prog after disassembly.
Give it a try.

Continental (DSM)

Siemens (ISM)
