No Adblue / No ADAS

[Karearea]

My Adblue warning came on yesterday and it says I have 1600 km range left.
It flashes up every couple of minutes so I don't think anyone can blame the vehicle if they run out, as you say.
I have a 10 litre container in the shed so I will top it up shortly.

Ok, happy to admit I’m a dumbarse here (well after all it took me ages to update my screen to include outside temp!) Anyway….
I drove for over 159km the other day looking for the “remaining range” for adblue and failed to find it!
This question is similar but more advanced than admitting I need to read the instructions but…
Please tell me how to find this information

I just took some pictures from my car.
There are two ways you can get the information.
One is to cycle through the menu below fuel temp & gear using the "Trip" button on the end of the light stalk.
You may have to set this up in the settings menu first, I can't remember what factory default is.
The other is to go through the vehicle functions menu as below.

Bloody awesome thanks Dave I’m in Shitake now

No problem.
Happy to help where possible.

I don't understand what the problem is with the adblue.
Unless you are planning on driving 10,000 kms away from anywhere that might have some, or live on a continent where it doesn't exist then it is not a problem.

I can tell you first hand it’s not the additive, it’s the system which is the problem.

One minute I had an amber warning stating
adblue no restart 5500km
Minutes later that changes to 35km
Then after having it checked by the service folk.. a few days later warning “No restart in - - km”

Levels stated on the info screen were 80% add 4 litres

Then… a few weeks before the next service, No restart actually occurred in a car park after having driven for 2 hours. Was flatbedded to the service centre after two weeks I was advised that the adblue control module was buggered… I got the car back yesterday and this morning a new amber warning stating
”Adblue error” Adblue malfunction seek service..

I'm not against it in principle, the only issue I have is that the vehicle is essentially bricked when it runs out. For remote travel I think this is dangerous, a cracked hose, split tank or even a faulty sensor could leave you stranded in a perfectly good vehicle.

But doesn't that argument apply to an oil pipe, fuel pipe, fuel tank as well. Yes it adds one more " at risk " item but is no more risky than any other strategic system fitted to the vehicle. And it is only crippling if you stop the vehicle, it won't restart, whereas fuel and oil system failures are self stopping.

Since this is an active thread on ADAS discussion, I'm curious to ask two questions now that I have my Grenadier out of winter storage:

1) I have searched, but have found no reference to removing the hardware responsible for the ADAS warnings altogether... figured I'd ask, since I recall being similarly annoyed with 80s VWs (curiously, not my Vanagons). The doorbell chime in those cars could be removed in about 7 seconds by reaching down under the steering wheel and pulling out the relay responsible for it. Might the beep/bong come from a relay? Or is the consensus that it's through the audio system?

2) My rear door open alert went off soon after my low fuel warning. I jumped out of my seat for the first one and experienced similar terror the second time... except the rear door wasn't ajar. Is that sensor adjustable? Or just super sensitive?

ADAS warnings come through the infotainment - it is part of the software load and integrated with the front camera and the wheel sensors. You will not get rid of it without a serious fight.

The door sensors can be a bit sensitive; you can move them around to make them more consistent, but I'd make that a warranty job if at all possible, some of them are just plain broken!

All of those are risks for sure, but why add more? The add blue system is up there with things like the interior lights, heated seats etc, it's nice to have but you wouldn't want to link every system in the vehicle to a lockdown situation. The Aussies will freak out when this comes to Australia. imagine being in the middle of the desert when it refuses to start.. and also imagine having to leave it running for 3 days while you try and get to safety...

I got stuck in a hired Landrover when it ran out of adblue. In the city.
So I understand the problem.

But the hired LR was neglected in that the add blue had actually run out because people failed to fill it at some point in the last 5000km.
The Gren mentioned above failed because the system failed when it actually had plenty of add blue
Dissing the defender as some sort of defensive default is not a solution to a potentially dangerous problem.
Hopefully it’s a one off and not a inherent issue that rears its head in any significant percentage of vehicles

Long distance lorry drivers have been using ad blue for years. If it was problematic I can’t see how an entire industry based company n reliable long distance driving would tolerate that. It’s obviously a fault, let them find out why and fix it. The ad blue itself isnt the issue. It’s simply what component failed and why.

I wasn't dissing the defender.
Vehicle brand was merely a coincidence.
I was merely pointing out that I had the same experience of an otherwise completely serviceable vehicle being undriveable due to an unnecessary issue.
In my case it turned out the hire car company had no procedure at all to service the adblue during normal running of the vehicle.
They admitted that they didn't even know it needed the adblue to run and not long after this they dropped them from their fleet as being too maintenance intensive for this and other reasons.

AdBlue and emission systems breakdowns are common and a bigger cost to the industry then most would know. Most transport companies would ditch AdBlue if it was legal to do so, and there were not the large fines associated with its removal.

Critical failure of the adblue system (leak, loss of injector pressure etc) initiates a 300km countdown before no further restarts.

Honestly more troubled by EGR/operation at high altitude than adblue but that could yet prove to be a non issue.

AA report 2023 said they attended 23,000 adblue related breakdowns and the majority were related to driver /owner error. That plus adblue freezing (-11 degrees or less and it crystallises) or contamination appear to be almost all the reported problems. There appear to be very few true ad blue system failures although like any car part there are always some like pump failures, sensor failures etc. It can clearly fail but it’s not something I will lose sleep over. Same as I don’t lose sleep over a battery losing a cell unexpectedly. It can happen sure but is it on my list of worries - no, not even a little bit.

From an industry trucking forum;

AdBlue and emission systems breakdowns are common and a bigger cost to the industry then most would know. Most transport companies would ditch AdBlue if it was legal to do so, and there were not the large fines associated with its removal.

AdBlue systems, a key part of modern trucks' emission control, can often be a source of frustration for drivers and operators when they malfunction. Below, we explore a real-world case involving persistent AdBlue system issues, based on shared experiences and advice from seasoned truckers and mechanics.

The problem
The truck in question has undergone extensive repairs at a Scania service centre, including replacing the AdBlue pump, sensors, DPF filter, and a pressure sensor. Despite these efforts, the fault persists, leading to escalating costs and no resolution.

Insights from the community
Through shared experiences, several possible causes and solutions emerged. Here's a breakdown:

Wiring issues
Truck wiring, especially around the AdBlue system, tends to degrade around 700,000 km. Damaged or dodgy wiring can cause recurring issues despite component replacements. Inspect the loom connecting to the AdBlue pump and ensure it isn’t worn or damaged by nearby brackets.

NOx sensors
NOx sensors are critical for monitoring emissions. Even after replacing both sensors, some users reported issues with poor-quality replacements. It's essential to confirm the sensors are calibrated correctly and functioning as intended.

Blocked hoses or injectors
AdBlue system hoses and injectors can block up over time, especially following pump failures. Blockages can lead to excessive AdBlue consumption or trigger fault codes. Cleaning or replacing these components often resolves the problem.

Catalyst issues
A rock or buildup inside the catalyst caused by AdBlue residue can lead to overheating and trigger system faults. Cleaning or replacing the catalyst may be necessary in such cases.

AdBlue quality
Low-quality or old AdBlue can trigger faults. If the same supply has been used across multiple refills, consider switching to a new batch.

Turbo or exhaust contamination
If a turbo has blown and introduced oil into the exhaust, it could disrupt the AdBlue system's function. While not an issue in this case, it remains a common cause worth considering.

In summary (my interpretation);
I don’t think contamination, mechanical damage, wiring damage, or 700,000+ miles of wear are big concerns for most Ineos grenadier drivers. Freezing of ad-blue when stored prior to filling is an issue however that I think has potential for harm if doing a big drive and carrying it with you in cold climate conditions. That and poor quality /contaminated fluid would be my only concerns.

I recently topped up my adblue with 10 litres
I normally buy when on special and have 1-2 x 10 litre containers in my shed.
I have a 2 litre bottle in the vehicle for any emergencies, but honestly would just fill it up with bulk if going away for a week or more.
I claim them on tax as a maintenance item.
As you say any part can fail so runniong out can hardly be blamed on the manufacturer.

Owners can take steps to keep the system reliable. One of the biggest concerns for any 4x4 owners who do a lot of off road, dirt road dusty environment work, is keeping the fill spout and lid clean and limiting debris from falling in the tank. Removing tanks and cleaning is not fun as most don't have a drain plug. The fill neck may have a fine screen, but nearly all AdBlue systems don't have a filter like a fuel filter to stop fine silt going through the system. Other issue is AdBlue in storage is very susceptible heat and UV damage, its shelf life is considerably shortened over 40°C and it smells terrible when it has gone off.

One of my error symbols was the amber NOx with the fuel bowser,
So thanks for the info! I’ll tell the Geelong service team tomorrow when I drop it back in for the second round of adblue* (Whatever else) diagnostics…
My other favourite is the No restart in - - km’s

Today it began not turning over first turn of the key which was a symptom of when it failed to start the other week.
