Replace x1 timing chain

I think I'll be attempting this fairly soon for a friend, its a 2017 X1 118d manual with the N57 engine I think, front wheel drive, coming up to 200k now.

Having never done this before is it easiest if the whole unit (engine and gearbox) are removed from the car to work on it or is it just as easy to remove just the box and do it that way, obviously this is the transverse engine. I reckon it needs a new dual mass as well judging by the strange sounds it it making at the moment.

Due to not having a ramp to work under the car I think I'd prefer to take things out from the top as opposed to drop the subframe down from underneath whilst lying under it if it does need to come out, I do have an engine crane though.

That's a transverse setup, so realistically the whole lot comes out the top. Subframe stays in. Pull engine and box together with your crane, much easier than fighting the box in the car. And that 118d is an N47 not N57, just so you know. Do the DMF and clutch while it's out, no point going back in twice.

That's the way I'd like to do it, as for the engine code, I think I actually meant to type B47 instead of N57. I think the original engines were the N47 and then they upgraded them around 2014 or so to the B47, does that sound right for the 118d? not sure if the chain and what not are different in the two variants.
