    Hi
    A few questions re: AdBlue for those of you with the latest A6 Avant 40 TDI or 40 TDI Quattro:

    1) Is the AdBlue filler cap located next to the regular fuel cap?

    2) Can the AdBlue cap be opened by hand or does it need a special tool?

    3) Whats the capacity of the standard AdBlue tank?

    4) What sort of mileage do you get before the AdBlue warning light comes on? I believe it comes on when you have 1500 miles left.

    5) Finally, i believe the dealers charge a small fortune if you ask them to do an AdBlue fill up, supposed to be far cheaper buying the AdBlue yourself & topping up as & when required. Would something like this do the job?

    amazon.co.uk/CleanAirBlue-Adblue-Cans-Spout-total/dp/B01KOEMJIW

    Alternatively, can you fill up from the AdBlue dispensing pumps at Shell/BP/other fuel stations or perhaps the nozzles don't fit?

    Many thanks! :)

    Yes, its a small blue cap next to the diesel one under the flap.

    2) Can the AdBlue cap be opened by hand or does it need a special tool?
    It just unscrews like the diesel one, you get a inch wide tube with the AdBlue stuff and you pour it in.

    3) Whats the capacity of the standard AdBlue tank?
    I am not sure, but I got about 3/4 of a 5 L in there just after purchase.

    4) What sort of mileage do you get before the AdBlue warning light comes on? I believe it comes on when you have 1500 miles left.
    We have done around 10,000 and havent needed to put more yet and its still showing as >2,400 km.

    Lastly, regardless of what they say, its not made of pig wee!

    Thanks mate, much appreciated. Never owned a diesel with AdBlue before so its all a bit new for me. A6 diesel is currently on factory order so want to be fully prepared for it. Thanks again :icon thumright:

    24l for the standard Adblue tank, the fluid though is made up of a mix of high grade urea, higher than found in cosmetics, glue or fertilisers. and deionized water...
