They use it to get the emissions down and it affects tax bracket. Therefore it is compulsory in a car that uses it. Therefore there is a 1500 mile warning (might vary) which ticks down and when it reaches zero the car won't start.

Can that be defeated by filling the adblue tank with distilled water so it thinks it has adblue in it?

Perhaps there is some detector in the exhaust system to prevent such a cheat.

Probably, but you wouldn't get far after it gets mixed with the fuel.

But AdBlue isn't mixed with the fuel.  

AdBlue is added to your exhaust and mixes with the fumes your car produces. It reacts with nitrogen oxide gas (NOx gas) created by your engine and breaks it down into harmless nitrogen and water vapour

Didn't know that! I think it might just work!

I know nothing about adblue, but won't this mean the car trailing a plume of steam behind all the time?

Does the adblue concentration get checked at the MOT?

Looks like the shortage has been resolved:

Not much more than at present. Adblue is already mostly water.

Adblue is 32.5% urea and 67.5% deionised water and is injected into the exhaust stream. The water boils off leaving the Urea to form ammonia that helps reduce harmful emissions.

What impact would using distilled water have, given that the water in AdBlue is deionised? (The latter meaning minerals are removed, whereas they may still be present in distilled water)

Distillation and deionisation (by ion exchange) are two processes for achieving essentially the same water quality.

Most "distilled" water purchased from the local motor mart will have been produced through deionisation.

EDIT:  For clarity on this, "deionisation" would refer to any process by which the ions (salts) are removed from water.  The main ways that "deionised water" are produced are:
1. Distillation - boil the water so the salts are left behind and then condense the steam
2. Deionisation by Ion Exchange - pass the water through beds of resin, first to remove the cations (positively charged ions) and exchange for Hydrogen (H+), then the second resin to remove the anions (negatively charged ions) and exchange for Hydroxyl (OH-), then the H+ joins with the OH- to make water (H2O).
3. Reverse Osmosis (RO) - pass the water under high pressure through a membrane which allows the water to pass through but the ions (salts) stay behind as they are too big to go through the membrane.

So the shortage is limited to hardware chains that stock a small amount of motoring stuff?

Just checked some motor factors and the only issues seems to be getting a 50 gallon drum delivered before xmas...

1ltr to 20 litres available for next day delivery or collection.  Seems any scarcity will be people panic buying
whether they think they need it or not.

It may for a while but chances are you'll block the injectors and knacker the SCR's catalyst. Replacing the SCR will be very expensive.

Shortage sorted perhaps, but like I wrote, there's some price gouging going on.
Not suprising really, high demand and one national supplier.

There is an easy fix according to 

Auto Expert John Cadogan

Just update the software in the cars and trucks to not need the adblue.
Turn off the system, all fixed.
They use the worst diesel and petrol in the world, and tax ev cars more than ice cars.
Australia does not care about the environment it seems.

Pallet full of Adblue at Aldi last night so there is some around
