Well one thing is that if you're driving flat out it will consume a lot of fuel :-k

But also, provided it's still plumbed up as it was when new, any blockage in the air inlet would result in a loss of boost and without boost there would be no extra fuel.  If it's not smoking I'd suspect it's not fuelling is if on boost when it's not on boost, if you follow.

Having driven a TDi with a split hose, your description sounds about right.  Flat as a pancake and difficult to rev, revving it hard without boost might be the reason it's using high fuel, low gears could be the other.

Another, more horrible thought is that the timing has gone out, but I'm told that leads to coloured smoke too, especially on boost.

When i first bought my disco I was struggling to do 60 on the motorway and thought it was just a disco but doing a long motorway journey highlighted the problem.

the next day it chucked out clouds and clouds of white smoke and wouldnt move until the engine was hot and fogged over the town!

I would check the bottom pulley on the crank shaft to make sure the nut hasn't become loose as that is what happened to me and the crank shaft wore away and timing went out and the key way in the pulley was more like a quadroople key way!

Hope you dont have this problem but worth checking.
