4motion diff lock ?

[Power ut]

I've seen a t5.1 with rear diff lock ( had a type off plastic actuator mounted on the rear diff )
But on the 2018 rear diff chap said it had diff lock .I'm confused. Anyone know . Only details I have is.
4motion set up is from a 2018 204 2.0 diesal lwb
Rear diff module is 0ay 907 554 L

4Mo: with or without Diff Lock?

Any progress yet? What's involved in retro fitting the diff lock? Is is software or is it an addition to the rear diff unit. You need to change the Rear Diff to the Version with Diff-Lock. Than 2 Air Lines need to be installed and some Valves and a relais and the switch in dashboard. of course...
