Adblue / Additive Issues

[GiveMeABreak]

I can't comment on other suppliers, as I've only bought my kits form Easydiags as I know Jim has good quality kits and there is UK support supplied by his team which is a big plus to be honest. There's no way on earth we can determine what you are actually getting from aftermarket clones via a Forum. You would have to have some guaranteed assurance and make sure there is an easy returns system in place for any supplier you choose.

Easy Diags sells out quite fast because of the demand, but I'd give him a call and see when stock is due in, plus there's a member discount too - link here:

The figures here for adblue levels seem contradictory. Also does the eolys seem low considering a litre was topped up less than 10k miles ago

[Paul-R]

Have you been back to the garage that topped up the Eolys as I suggested? These are the same figures I found and are inconsistent with them saying that they've informed the system.

[Mexico14]

Not yet Paul. Wanted to double check figures first. But doesn't look like they reset it - I wonder how that would impact the DPF??

There was some other fault codes too. A couple were flagged up as important.

[GiveMeABreak]

The above doesn't show any faults.

How come the urea tank level shows 2 different figures? Should the eolys tank not show more than 44ml - would it use 956ml in less than 10k miles?

[GiveMeABreak]

These are separate systems, are you getting things mixed up?

Eolys Additive Tank: No this is not unusual, vehicles can be fitted with 1 or 3 litre tanks and your diagnostic screen clearly shows capacity of the additive when new as 1.10 Litres, so this indicates to me you have a 1 Litre tank fitted.

The estimated amount of fluid remaining is 44 ml so about 5%, but this is only estimated as I have mentioned several times - it is not physically measured. If the previous top up was not reset correctly then of course it is going to report an incorrect volume. The only way to check is to physically drain the tank and measure it.

I suggest the next time it is topped up that you take the before & after screens in Diagbox so you can compare the values once reset for peace of mind that it has been done correctly.

UREA (Adblue) Tank: I don't know what you are referring to. The third picture from a few post back shows that the UREA solution in the tank is more than 10 litres. What other value are you referring to?

But the point is that the tank was recently (10k miles ago) topped up and the garage says they informed the system of this. My readings, and the one above, show only 44ml estimated to be present so I have suggested that he goes back to the garage in question and ask them to put their code reader on (at no charge as this is a query on a previous job) and confirm that they have informed the system. I don't think they did this properly but I didn't want to reset it myself as they could then claim someone else had interfered.

[GiveMeABreak]

I can't confirm that, I'm just stating the reasons why it may not be.

[Paul-R]

Confirm what? I don't understand?

[GiveMeABreak]

I'm saying Paul, that I personally cannot confirm that the garage has done the job properly! - and after dealing with enough posts on this I'm not surprised as it can be difficult to do on some systems where it won't reset and needs dealer intervention with proper equipment to do.

Yes I understand the 2 systems run independently from each other.

On 1 screen it said the urea had more than 10 litres (bizarrely on Paul's machine it indicated 6.1) on another it sys 0.0. That's the confusing part.

Also confusing is that the car thinks the eolys is very low but no warnings or fault codes to be relating to that.

It looks like the wiring repair has got rid of the nox fault codes as well as the previous adblue issue. 3 problems sorted for the price of 1?

[GiveMeABreak]

Re the Eolys additive, it depends on what your maintenance indicator says - specifically how many miles until your next service is due. If the engine ECU determines the additive quantity is insufficient to cover the distance until your next service, it will flag a warning up - unless the system is faulty of course.

As for the Adblue, some settings will change depending when the vehicle is running or a few minutes after ignition is switched off. Things like the temperature and the pressure determine whether the pump runs or not. I don't have all the detail on this system.

Cheers Marc that would make sense.
Now I've found another screen that suggests there is 1029 ml of additive in the additive tank out of 1100ml reservoir volume. So 71ml used or 7% used.
I wonder if it needed to be reset in 2 separate Ecus hence the 2 different figures.

[Mexico14]

Are these 2 screens reading from the eolys pump? Note the one with the lower figure states "quantity of product remaining in the flexible additive reservoir in ml" - what exactly is the "flexible additive reservoir" - is that referring to the Eolys bags? I thought my car had rigid tank?
