The latest GTD (WLTP) uses adblue does it not?
I assume that the Mk8 will too...
I've never had an oil burner that uses it.
How much does it cost? How many miles do you get from a tank of adblue? Is it a pain in the butt?
-
How many miles you get depends on how many miles you drive. My Tiguan r line had ad blue and it was only a pain to refill because the filler was in the boot. Newer cars have the ad blue next to diesel filler cap. In theory you can go between services without filling up in reality you won't. Plenty of service stations now have ad blue for sale at the pump or you can buy it in bottles. I bought my stuff from tps but seeing as they are trade only now eBay might be worth a try. Oh and it's not pigs wee either before anyone tells you it is :grin:
-
So its thousands of miles, not hundreds to a adblue refill?
-
Definitely thousands Fred not hundreds 👍
-
I've gone through 10L in 11k miles, so I think 1L/1000 miles currently. I do 40-45k a year, so I'll let you know if it changes!
-
How many litres in the tank? Do you get any indication of level or just a warning light when its empty?
-
I have no experience with the stuff in VW’s but have around 40 vehicles parked in the yard at work that drink the stuff.
The lorries get through a fair bit but in the smaller vans a tankful lasts quite a while.
Although not pig pee anymore it can and does still leave a white crystal type residue if you spill it.
The exhaust needs to be properly hot for it to work and there’s minimal visible exhaust fumes when it’s woeking properly. Good for shiny tailpipes is think!

if those are motorway miles then it'll use less ad blue. It's all down to driving conditions and no two amounts of ad blue will give you the same miles. Don't spill any on your paintwork either 👍

it only adds a few drops per full tank of fuel ..so should last a while , (well it does in the cars we build not to sure about vw)

it depends on what driving conditions the car is under!

I was a bit peeved when I found out our Tig used it. It uses about as much as the others have said, so doesn't need filling that often. However, seeing as our Tig was first designed lots of years ago, filling is via a hole in the boot floor which is a proper pain.
New cars with it engineered in have more accessible filling. I've just bought a new Caravelle, and its filler is behind the fuel filler flap.
Both vehicles give an indication of when they needs filling. The Tig gives a warning and countdown from 1500 miles, the 'Velle gives a range in whole 100's of miles in the MFD. It is advised not to let the range drop below 500 miles and that you should put at least 5 litres in when topping up.
Apart from the Tigs filler location, it's no more of a chore than topping up the screenwash.

Thanks guys, some useful comments here.
Seems like I don't have much to fear if I get another GTD.
-
Does the gtd definitely use ad blue?
-
yes, the GTD does, I have a 19 plate just over a month old now, and this has the adblue cap next to the diesel fill cap

Nope. Bout 50/50 motorway/minor roads. So I think its a fair idea of how much someone will use :wink:
I've spilt some on the floor and it does leave a white stain, but it does wash away, so i think its safe to say its pretty water soluble.
-
Someone on the Tiguan forum spilt some on the boot floor when filling and it took the paint off so I'd say it's not pretty water soluble. I'm sure it says on the side of the bottle to not get it on your skin or paint work.

They weren't using some home made stuff were they? The proper stuff has a pH of 9.5, making it as caustic/corrosive as unmoisturused hand soap. It's just Urea:Water in a 1:2 ratio. Easy to make, but purity of the Urea and water (purified/deionised) is paramount to avoid contamination or poisoning of the SCR catalyst or clogging the delivery system through crystallization of the Urea.
Urea and water is basically what's in your piss, with a few other additives your body throws into the mix to get out of your system. Urea is pretty water soluble.
I'd be surprised if adblue munches through paintwork.
-
Was genuine adblue and it stripped the top coat off. It does say on the tub to not spill any on paint work.

Meant to post these the other week, it’s adblue residue around the base of the tank and pump at my workplace

That'll be crystalline Urea. Someone spills, the water evaporates, and there's a deposit of the Urea that's dropped out of solution as the water has evaporated.
