I live in the UK, not sure how many filling stations have adblue pumps for cars? Anyone in the UK care to comment

Master_PiT

in shops at stations they have 1-20liters ADblue

Isn't it better to fill up from pump as adblue has to be used in one go, so you get ripped off for buying small container or waste it if you use a big container, using a pump would you can pay for just what you use

Master_PiT

maybe. But I see this only in big city, and you dont know what quality it is.

you need only few liters

MB UK have a FAQ page here:

Be aware, the AdBlue tanks come in different sizes. The new models have a much bigger SCR-tank that should manage between two maintenance visits. The older cars only managed 7000 km.

What's AdBlue??

hummerhealey

AdBlue is a Ureum solution that's injected to reduce NOx. It's only used for diesels.

Perhaps the dealer should have filled the AdBlue tank when the car was delivered to the customer? I understand they do not fill it up at the factory because the car may stay at the shop for a long time which is not good for AdBlue.

Seems my V222 was filled up at the factory (as well as the fuel tank, it was picked up from Sindelfingen). Just recently filled the AdBlue tank before the first service at 10200 km. 5.5 litres was enough to make it full. Could have managed four years without refilling.

I have a 200 l canister at home (for bigger vehicles that also need AdBlue). Easy to fill up if reading the AdBlue level with the Star diagnosis tool, there is no level indicator at the instrument cluster menus and I don't have the filler pipe that should come with the small canisters.

The AdBlue tank in the car is about 26 litres, would have been better not to fill it up at all but I was afraid MB techs would have filled it at the first service and would have charged a fortune.

and only to the bluetec models. The previous nomenclature for MB diesels was CDI which is considered too pollutant does not have this new technology of using AdBlue

It's not that the CDIs were not as polluting it's the new stricter emission laws in Europe (Euro6) that require the ad Blue system so that they reduce NOx to similar levels as petrol. Those with Ad Blue are therefore much less polluting (although I think the system is truly only affective when the engine is fully warmed). Trucks in Europe have been using Ad Blue for a number of years.

^^ sorry i edited my comment. I meant to say that the CDI was too polluting.
