How to download Launch M-Diag Lite software

Finally, i received the Launch M-Diag Lite OBD2 diagnostic scanner adapter ($49 i spent).

Scan the QR code on the M-Diag manual (the box, the tool also with it)

A tip here: better use the browser app to scan the code; Chinese wechat cannot appear the download link after scanning






Download then install the Launch M-Diag App

Open M-diag


First, sign up  for M-diag

ok to login with the user name and pass

Then, activate the M-Diag with the S/N and A/C

My tip: find them in the password envelope


This is what i did for the binding (the Launch M-Diag Lite code reader and user)

Easy, i think.

Last tip!! Most important one!

It’s about software download:

The car software and sw for special functions first!!!!!!!!

And then demo & eobd…

I don’t know why it is the order

But it’s a must. My vendor told me.

Edit: have a quick test on my BMW 520Li 2014

Pleased to see that all OK.
