Ducato Ad Blue usage

[royandsharont]

I’ve had a look at the App, it doesn’t show 2 garages close to me that I know have pumps but does show others I know that do have it. Perhaps it depends on the supplier to the station?

That could well be the case. I used one in Wales that isn’t shown on the app but it is a newly opened services so I wasn’t sure of the reason for it not being on there.

Shows one at a garage near me that I wouldn't of expected to have it ill have check. Looks promising as it doesn't show the ones that don't have pumps that appear on other sites.

I can see an Adblue pump on street scene at the Manor Road Esso if this is the one you are thinking of.

Yep that's the one, last place I would expect to find one none of the bigger garages have them.

I had one fill up at a motorway service in UK but the pump didn't cut off and so over filled. The Adblue was at the truck fuel part of the station. I thought oh no I'm not supposed to over fill. Motorhome started ok so don't know if any damage done. Gauge hasn't moved since so far.

We have a 2022 2.2 140 bhp Ducato PVC with Manual gearbox which we run at about 3.3 tons. It our first vehicle requiring Adblue and I've recorded every top up since new. We too have averaged 283 miles per litre over 15k miles.

As a contrast we have a 2020 Ducato 2.3 140bhp coach built. Up plated to 4T and we run at about 3.8T. Done 28,000 miles and average around 180 miles per litre.

 

[Greygappers]

We get on average 1200 miles per 5 litres. 2020 ducato camper van ( auto). This is the average over 4 years and about 30,000 miles. We just put 5 litres in every time the warning comes on on the dash. Hope this helps

Ok since new Jan 2020 (yes a bit anal) 202.893 litres for 32168 miles or 802.62 MPG

Does anyone have details of their Ad Blue usage for a year old Ducato? eg what mileage might I expect for 10 litres?

I know it depends on many things, including driving style, but any details would be useful.

And does anyone know the tank size? The manual is less than useless.

Hi I’ve recently have been putting in 5 litres every 1K miles as warning light comes on! I’m not too sure if this is excessive maybe some on this site can advise? I now carry a spare 5 litres can for every trip, as buying from fore courts can be very expensive. You can buy 20 litres on line for £20 so I stock up and refill can, the ad blue tank is 19.5 litres I read somewhere. Best of luck

Don’t know what mine uses, 2020 Rapido 2.3….. but the first time it throws a fault will be the last, I’ll get it mapped out.

I understand that the warning light comes on around half full - I know it's a bit worrying, but there's plenty of mileage still to go. I think your 200 miles per litre is a little on the low side, but according to the above comments there is a very wide variation! I don't know where you tour, if it's in the UK then it's probably wise to carry the stuff with you.

The only sure way to know how much the tank can take when refilling is to use a pump - that will fill it but not overflow it - and they are widely available in some EU countries (but not in the wonderful UK, of course).

In the past I haven't bothered too much, but from now on I intend to keep a record so I know where I stand - and recording mileage since the last refill and using a pump would seem to be the only way?

There seems to be a marked difference between HP variants.
I have a 4.5t last of the 2.3 engines at 160 bhp 9 speed auto..6d temp engine , 2021 reg.
Light used to come on 600-700 miles took about 8 to 8.5L.
Over 3 years it has gradually crept up now doing 900 odd miles to the light.
The 140 bhp engine seems to use a lot less, as expected less fuel less Adblue usage .
The later 2.2 L appear to use less Adblue in 140 and 180 variants .
I was surprised at the amount of usage on my 160 , but appears to be inline with others with this engine, trans and weight combo..

Having been alarmed at the consumption of a new Knaus Ti Vansation back in 2021 I asked what Fiat official figures were suggested in order to investigate attention under warranty. To my surprise the consumption criteria is quite heigh and so no action was considered necessary and I was even more disappointed when Ad Blu doubled in price very quickly after a year or so.

The main dealer provided me with the figures Fiat use when considering action after a complaint. Another concern do me is that it appears that Ad Blu has a shelf life when exposed to the atmosphere so my initial plan to buy a larger 10 or even 2ltr container of the stuff from a commercial parts supplier was quite the wrong thing for me and possibly many other relatively low mileage M/H owners. Just a thought.

DUCATO (290/295) – UREA DOSING CONTROL UNIT (DCU)
Urea consumption – Network Information
APPLICABILITY
2.3 Mjet Euro 6D Temp
Cancels and replaces SN 10,009.20 of 12/06/2020
CLAIMED FAULT
The customer complains of excessive urea consumption.
The customer complains of the appearance of an inducement message without an indication of the kilometers on the instrument panel after adding urea.
GENERAL INFORMATION
The Ducato has a 19 liter urea reservoir.
The indicative urea consumption for each type of route in ordinary driving conditions is:
Indicative urea consumption (litres/1000km)
Version
Urban
Extra- urban
Motorway
Mixed route (average)
Van / Panorama
Up to 2.0
Up to 2.0
Up to 6.0
3.0
Camper / Motorhome
Up to 2.5
Up to 2.5
Up to 7.0
4.0
Insulated with refrigerator box
Up to 3.5
Up to 3.5
Up to 9.0
5.5
Evidently, these values may be strongly influenced by the type of route (urban/extra urban/highway/mountain roads), but also driving style, load and environmental conditions. At high speed (e.g. 150km/h, speed allowed on some motorways in
1

Germany) or transients at full load, consumption may increase even more than that shown in the table. An urban driving mission characterized by sudden accelerations, for example, would require more work by the system to abate pollutants with consequent increase in urea consumption with respect to the values given above.
Additional considerations:
● Some customers who already had E6b vehicles with a urea injection system could complain of excessive consumption in comparison with the previous emissions standard. Refer to the values provided previously and explain how the tightening of the standard has required greater urea use.
● The appearance of the message on the panel (“inducement”) is initially only a warning and does not indicate the residual range of urea. When the customer has only the message, the range is between 600 and 1500km (depending on when the message appeared the first time). As the range decreases, the residual kilometers appear that, once driven, prevent the vehicle from being started.
The message is not related to the effective quantity of urea in the reservoir, but the estimate of the residual kilometer range.
High urea consumption due to the combination of high speed/particular versions can lead to the message ("inducement" without the indication of kilometers) appearing on the panel also after filling up the reservoir completely.
● The system is able to diagnose abnormal urea consumption related to a possible malfunction, displaying the suitable error code. If there is no error code, the message on the panel is related to the estimate of the residual kilometer range and not to malfunctions; therefore no components require replacement.
The average urea consumption from the beginning of life car can be calculated using the diagnostic tool as described below.
• Using the diagnostics tool updated to the most recent software release, access vehicle view, select the urea system control module (DCU – Dosing Control Unit) and open the Data tab.
• On the Data tab, select the "Total consumed urea" item to display a value that indicates how many grams of urea have been consumed since the beginning of the car's life
• To determine the value in litres, divide the value in grams by 1.087 (specific weight of urea) and divide the result by 1000.
• To determine the average urea consumption expressed in liters/1000km, divide the previously obtained value in liters by the total kilometers driven by the vehicle
Example
For a vehicle with total of 11200 km and value of 30436 grams detected with the diagnostic tool, the result is:
• Total of 28 litres of urea consumed since the beginning life car (30436 divided by 1.087, and the result divided again by 1000).
• Average consumption of 2.5 litres of urea times 1000 km (28 times 1000 divided by 11200).

Filled (at a service station) last week after about 6000km since last fill. I was expecting it would take full tank but overflowed with a little more than 4 ltr. Needless to say this concerned me since I read all the warnings not to fill to overflow, so next morning I set about sucking (with pump, not mouth!) some of the AdBlue out of the tank. I discovered that the tube I was inserting into the filler pipe was showing no sign of getting wet with AB even after pushing it in to a depth of over 15 inches. There must have been a temporary air bubble in the filler pipe when I was filling it the day before so I've drawn this conclusion - the flow rate from the pump was too great and caused a sudden gush back or air bubble and caused an overflow. Has anyone else had this experience?

And does anyone know the tank size? The manual is less than useless.

My manual says it’s 14 litres, I filled it and set off to Spain, after 1412 miles the adblue light came on and I put 10.3 litres in the tank. After another 1100 miles up hill and dale, I put 8.7 litres in then after driving 232 miles I put 1.2 litres in. So motorway first check, motorway and nationals second trip, UK pain in butt driving final recording.
To be honest I can’t be bothered checking any more.

 

[Apacheman]

As stated in a previous post we generally get about 180 miles per litre. I take a picture of the mileage when I top up and about 18-1900 miles later put another 10 litres in. Max it’s ever taken is about 12L after the warning lights came on. Occasionally I have overfilled, even using a garage pump it’s poured out before cut off. Only problem I’ve had is residue if not cleaned off properly at the time. How many others have done the same and how many resulted in a mechanical or electrical problem? Just interested to know if overfilling is such a no no!

Yep, I can’t fill mine just by squeezing the pump handle, it’s got to be a lesser squeeze to keep the flow going if you know what I mean.

In terms of consumption I’m at 888 mpg or 200 miles per ltr

 

[gus-lopez]

I have not been closely checking the consumption of AdBlue, however, I have added 3 times to the tank since new. First time was 8 euros, second time was 9 and last time was 9 again I seem to remember so a total of 26 euros. A litre of the stuff is around 90 cents so that makes 28,88 litres in 6,444 km. The tank is at almost full right now so the math doesn't make too much sense as that would be 223 km/litre, I imagine I'll be getting around 320km a litre more or less. Does that make sense?

But was it full when new?

 

[Barriesimpson]

I'm not sure to be honest, I don't remember but I think it wasn't and that was the first fill after picking up the van.

Aldi sell it in the Middle Isle. Cheaper than anywhere else too.
