Just quickly I can say, challenging moments so far,It would be nice if you could list any problem areas after you have finished this job. I have a 2014 Multijet and this is next on my list after I have done the propshaft. I have all the parts so am ready to go but any gnarly areas you encounter it would be great to know about.
Exhaust section under the sump, removal is difficult, I ended up pulling the centre section rearwards on the rubbers with a small ratchet strap, If rusted into downpipe and centre section I would consider cutting in half and removing then weld together to replace or just buy a new one.
Block to gearbox bracket, one fixing is directly above the 4 wheel drive unit, I tried about 10 small 13mm sockets before I found a wera 1/4 drive on Amazon that would fit. I tried an open end crows foot but it started to round the head. The flare nut crows foot might also have worked but bolt was out by the time it arrived.

Then the bracket will not come out before the sump, but they will come out together, heaven alone knows how they go back in place, I was going to practice before applying the silicon to the sump.
Draining coolant, remove intercooler pipe from intercooler and remove bottom hose . Nice video from Haynes helped.
Engine mount bracket is very tight to chassis leg, came out to the rear and down
Good luck, I will add as I think of things.
