Maybe sound a silly question- but do you have identical tyres/wheels on all four corners? 2014 SE Loire Blue SD4 Auto (MY15)

I have just nipped out to check and they are

Front Axle Michelin Diamaris 4 x 4 235/60 R18

Rear Axle Continental Cross Country 235/60 R18

What I find strange is that the car gives the fault after about 2 mins

Ignition on and terrain command module lights up (Normal car illuminated) and if I rotate the knob it shows the other programmes but it gives the error after 2 mins, lights go out on the module and I get the small window error message.
