For those who are intrigued.....

AdBlue: Selective Catalytic Reduction (SCR) Advanced emissions control for diesel engines.

 

And a short VW  video http://youtu.be/pfKo-S2PMY0 to explain

Some places will charge a fortune for a litre of AdBlue. The filler for it is right next to the fuel filler that is behind the fuel filler flap.

Which Superb 3s have to use this, if any?

All diesels I believe.

The 190 and above diesel's require adblue

The 150 and below just have dpf

Thanks for that, I'm looking at the 150 diesel and the ACT petrol but leaning towards 4x4 only available with the diesel at that power point but if it needed AdBlue I'd go 2x2 petrol (which, in view of the very low mileage I achieve is actually the most sensible choice!).

If when you look at engine specs it says scr it requires adblue

I do low mileage and was thinking act petrol but diesel has much more torque, which is what I missed going from a 140 diesel to a 160 tsi superb.

 

So ordered 150 diesel, holds better value on trade in as well.  

And diesel is now cheaper than petrol [emoji106]

So if it uses adblue are DPF regen cycles no longer required?

The AdBlue is to clean up the increased NOx from DPF regenerations.

 

The DPF cleans up particulates (soot). Which is increased by the EGR.

Some places will charge a fortune for a litre of AdBlue.

 

The local BP in Dover has been selling it (via the pump) for 59p per litre for a while now, but you do need to shop around as I have also seen it 3 x this price!

By a fortune I had heard of £'s per litre!

I was sceptical of that being as my new Yeti tdi 110PS has Adblue but you are absolutely right.

 

Took some searching as Skoda web-site and brochure are very quiet on the matter but found a report on Honest Johns which says:

 

The diesel engines achieve EU6 by virtue of their integrated exhaust manifold (manifold in head). Only the 2.0 litre190PS SCR version needs AdBlue. The economy champ is the 1.6TDI 110 DSG that manages 70.6mpg in the ECDC drive cycle and 105g/km CO2.

 

We've been fobbed off with the "old tech" in our Yetis! The bodge that is Adblue.

No diesel for me. DPF + AdBlue = Buy A Petrol!

AdBlue is a Urea compound. Urea is a natural product in urine. Pee in the tank, it will be cheaper.  :no:

Do you think you could apply for a reduction in the sewage rates!

I wonder why it isn't called AdYellow

The 150 4x4 also uses Adblue.

I thought as of September all diesel cars had to have Adblue as part of Euro 6?

 

Presumably some models must have achieved Euro 6 without it

 

Must admit from now on I'm sticking to petrol

I don't get the reluctance for using AdBlue. Seems like it's a good thing for the environment and reducing air pollution (the air we all breath). The Superb AdBlue tank is 13 litres. Using approx 1 litre of AdBlue per 1000km gives a range of around 8000 miles per tank. If you top it up when the low level warning light comes on, then you can still get around 6500 miles. That's quite a big range between fill ups so I can't see it being hugely inconvenient.

I think it's great news, especially for city-dwellers.

 

People are naturally cautious about change though, and there is clearly a potential for this system to add to the longish list of 'things that can go expensively wrong'.  One would hope that the prior experience of its use in commercial vehicles will have ironed out some of the teething troubles.

 

A few years back I used to work for a company that was paid to try to develop a sensor that could tell whether what was in an Adblue tank was really Adblue, and whether it was at the right level of concentration. Presumably to prevent people peeing into their tanks, or adding straight water.   We never got anywhere near to producing a working sensor. I wonder what they've ended up with, if anything.

Presumably to prevent people peeing into their tanks, or adding straight water.

Do people really do that, pee in the tank? I was, of course, joking when I said it. I would think with all the other harmful materials in urine it would quickly destroy the system.

I also read that AdBlue starts to break down at 30ºC so I'd hope some kind of temperature protection is built into the system.

 

I suspect much of the adversity to AdBlue is the additional motoring cost (in some places the price of AdBlue can best be described as extortionate) and it gives the sense of harking back to two-stroke when you had to add oil to your tank (for those that remember two-stroke, the king of polluters).

 

I'm switching from diesel to petrol but it has nothing to do with AdBlue (I wasn't even aware of AdBlue being used by the new Škoda/VAG diesels when I ordered the new car).

Dunno. The fact that they were desperate enough for a sensor to ask us suggests that there was an expected or proven need for it.

I really don't understand anyone who is adverse to AdBlue due to the cost. The range you get between fill ups is massive (you even get 2400km range when the low warning light comes on), so only those who are really really badly organised would be subjected to an extortionate price. A reasonable price seems to be around 50p to £1 per litre which is pretty insignificant in the grand scheme of cost of motoring. I suspect anyone complaining about the cost has some hidden other issue with AdBlue.
