I am sure this has been brought up before, but cant find it on the Forum.
I have a MY17 Autobiography, it needs filling with Ad Blue every 4k-4.5k. Is this normal?
I have a service contract, so its done FOC, but its just a right pain having to go to the dealers every 3 months and wait for it to be done.

I bought a DS with Adblue and it was using twice as much as advertised - according to owners on forums we are not alone  Wanted a Series 2 LR since childhood but previously owned MY16 Disco Sport HSE TD4 Auto, MY13 RR Sport Black Edition TDV6 Auto, MY10 RR Sport HSE TDV6 Auto, 2007 Freelander 1 Freestyle TD4 Soft Top, 2009 Freelander 2 GS TD4 Auto, 2007 Freelander 2 GS TD4, 2004 Disco 2 Metropolis Auto, 2002 Disco 2 GS, 2000 Freelander 1 SE TD4 SW

Still hoping for a S2 one day!

My MY16 has just returned from its second service. Never needed adblue top-up between services and just before going into service it has shown a good few thousand miles until adblue top-up required on both occasions. Car has covered 17.5k miles and is driven in London in slow traffic regularly. Current: Volvo XC90 T8 Inscription Pro PHEV with some optionals on top

I have just filled it up last weekend, have only done slightly more than 5k miles. Mine is MY17 as well...
I remember seeing people saying one full tank can do 12k miles+, so was really surprised when I received the message..

Sumting wrong if you are using a full Adblue tank every 5k miles. MY2016 HSE D SDV6 - gone due to fuel dilution problems.

It can depend a lot on driving style as it is a selective catalyst reduction system. Meaning it only uses add blue when it sees excess in Emissions
. I find the harder i drive the more you use, why some one who plods arround won't use as much but if you like to give it beans you will use more

Mine did 11 months and 9500miles before the warning came on. Mixed driving..... 6 bottles.... Gone:

SCR is very temperature dependent. The rate of adblue dosing will depend on the level of NOx sensed at the front of the catalyst (which will depend on the load on the engine and engine exhaust temp), coupled with the temperature of the SCR catalyst bed. If the catalyst is cool (slow city driving may never see it warm up) it will not dose much at all, to avoid ammonia slip from the tailpipe (which is not a good thing!). Under nice hot motorway driving, you will see the optimal level of dosing and excellent NOx reduction. When working properly it is astonishingly good at NOx reduction. 90% reduction is quite achievable, bringing NOx emissions down to the level of a petrol equipped with 3-way catalytic convertor.

So, all of this pre-amble means that adblue consumption is directly linked to your driving patterns.

For last 2 years I managed to do around 10,000 miles for each full tank of Ad blue.

Well, getting 3500-4000 miles. Dealer has now said that is what is expected from a MY2017 !!!
So that is going to be 4 visits at least a year, waiting around for 40 mins. I could do it myself in 10 mins, but why should I. I have paid the extra for service plan which includes Ad Blue

I can't decide whether to call your dealer stupid or crooked. The Adblue tank was always sized to last between services. MY2016 HSE D SDV6 - gone due to fuel dilution problems.

Weren't there some engine setting changes for MY17 which might have an effect?

The adblue consumption rate is simply a function of the number of times that the car meets the conditions for NOx reduction ( based upon exhaust temperature and NOx production rate) versus the size of the storage tank.

If there have been changes to the dosing strategy (in all probability there might be to meet the requirements of the new WLTC (world harmonized test cycle) and the RDE on-road verification of emissions (Real Driving Emissions) both of which began in 2017), Then that would account for an increased consumption rate.

This is the state of the art for diesel emissions control for the foreseeable future (until we all buy petrol-electric hybrids) so you may as well get used to topping up the adblue, like when you refill the washer bottle. I wouldn`t bother driving all the way to the dealer and waiting around for a thoroughly routine task.

Mine has been filled twice in 2years both during routine service ( done today). The warning came on on Friday but it was already booked in for the service. Total mileage 23700 so 12000 between fill ups. Notice on the invoice it took 17 litres to fill up  MY16 AUTOBIOGRAPHY Indus silver with some toys
