VXDIAG or Mongoose for Volvo VDASH?

As titled, VXDIAG and Mongoose which is a better diagnostic interface for Volvo VDASH software?

Here is the clue.

Mongoose:

VDASH has added support for Mongoose, but it must be an original device.

mongoose clone doesn’t work with VDash.  But he works fine with vida.

There’re plenty of various devices on the market, best one are J2534-devices compatible with Super J2534 or Mongoose JLR.

Another option is VXDIAG (VCM II – Rotunda Diagnostics or compatible). The basic diagnostics seem to work, the DIM languages have been tested too. The overall functionality is briefly the same.

Some are reporting that VXDIAG doesn’t work with the VDASH program. Others have tested it and it turns out the program recognizes the adapter and connects to the car without any problems.

Which is better for VDASH?

VXDIAG is slower in P3 CEM pin decoding than DiCE or Mongoose interface, but it works.

We don’t recommend using VXDIAG Volvo for ECU programming (language change, configuration change, engine optimizations).
Using VXDIAG for ECU programing is at your own risk.
