Is it true that Jaguar and Land rover Pathfinder will be shut down in April?

Yes Topix cloud diagnostic only from April.

With Topix cloud you can do only diagnosis, no programming modules and so on. Just basic things.

The cracked version should still work.
You can’t update anymore, they have new software engineering mode and will replace the functions- “Pluto”
Only dealer can do now, they didn’t release for public, same as Mercedes’ policy.
All diagnostics are going this way. Volvo is already online, many others will follow.
JLR SDD is separate from Pathfinder so vehicles up to 2016/17 will still be OK.
