I have not said to ignore the manufacturers advice. All I’m saying is that contrary to some views the car will not stop when running out of adblue. It goes into a lower power mode but if switched off it will not restart until a minimum quantity of adblue is added. Clearly with the dashboard warning acdriver would have to be a Richard Head to get to a run out situation.
But Clive you have contradicted and questioned the manufacturers advice. I for one would not listen to the AA or RAC instead of VW in my case.
Now now, you Boys, a message like that from the AA or RAC, is inappropriate as different manufactures will have there own systems.
Shut down systems so that when AdBlue is not injected into the fuel system as to prevent the engine running other wise the "No" levels are not as advertised and would risk prosocution ( no spell check )by athorities
To unilaterally dismiss RAC, AA etc isn't logical, even though I agree that the car makers advice is paramount. But this link from VW UK clearly states the position. It will continue to run without adblue but it will not restart once switched off. There's a similar one from MB UK Syntner.

IEarly Adblue systems were more difficult to refill or top up needing dealer inputs, but most modern ones are driver refillable. Also if the tank were to empty it may need purging/bleeding. But it wouldn't be beyond the designers capability to ensure that when the system showed empty a minimum quantity was left in the tank to obviate the need for bleeding etc. My 2010 Volvo D5 had such system to show engine oil at the correct level, when in fact to protect the cars engine during failed DPF regeneration Volvo decided a reduced sump oil quantity was required.This allowed at least 0.5 litre of fuel to sit it the sump without sounding a high oil level alarm. That is the beauty of electronic systems they can be configured relatively easily.
Adblue does not go into the fuel system. Its part of the Selective Catalytic Reduction system and used downstream of the fuel system.
Here is an interesting artical, if you can believe Wiki.
I always thought UREA was used in ships exhaust sytems first. OC over to you.

Sorry Clive that’s lost on me. If my engine gets switched off in that scenario I’ve had it. The VW Dealer in Birmingham was very specific about the warnings for the Adblue and the repercussions. That’s good enough for me. I could be in the middle of no where in Sutherland. What then?? I’m not sure what this discussion is really bringing to the table 🤔🤔To unilaterally dismiss RAC, AA etc isn't logical, even though I agree that the car makers advice is paramount.

The answer to your question is, you should have bought a 2014 SantaFe instead of your Towrag. 😂 No need for AdBlue.
Yes it was initially used in ships diesel engine system under rules introduced by the International Maritime Organisation MARPOL regulations.

To be sure, the Adblue mention I made in post #16 was specifically related to an Ablue feed fault. Nothing to do with running out or getting low. So not sure how it sparked this debate.
At 2013 my car does not use Adblue, but a previous Puegeot 4007 2009 had a strange system. I don’t know if it was Adblue or something else. But this was in a shallow tank which held a bladder full of the stuff which lasted 80,000 miles. In my case the bladder split at 40,000. It was a dealer replacement job.

As all threads move around, we will be onto when the Crayon Factory in Bedford stopped production of the ADBlue colour.
It was probably a tank for the DPF regeneration fluid. This was a system used instead of injecting extra fuel into the engine, or injecting fuel downstream of the exhaust manifold. It was for regenerating the DPF.
It's 1500 miles for solo use but mine seems to count down at quadruple the rate when towing !
The engine won't cut-out, even when the Adblue is empty - what happens is that the engine won't start when it's empty - doesn't need a dealer reset, just add 6 litres of Adblue, or more, then switch on engine for 30 seconds without trying to start the engine, then switch off and use normally from then.
Thanks Roger. That is a very useful piece of information. Makes you wonder why the VW Dealer didn’t know this
As per the link from Volkswagen UK in my post at #30.plus a bit more info from Roger L if it doesrun out.
Our car is a diesel Jeep and does not use Adblue whatever that is so doubt if it is causing the Engine Management light to come on.
Thanks Clive. Just goes to show you can’t believe everything a Dealer tells you🤬🤬
Hi Dusty my Adblue warning came on my Tiguan when we was away at present we are on 1200 miles rang them it book in for a MOT end of this month we will sort it for you at the VW dealer
