Hi, I have a 2016 XF 180bhp and every 2000 miles it throws up the “incorrect diesel exhaust exhaust fluid quality detected” message yet Jag are the only people to have ever put ad blue in to the car. When it first happened I took it to Jag and they charged my 2 hours plus VAT and all they did was to empty the Ad blue tank and refill it. 3000 miles later back it came. It’s a constant pain in the backside and no one seems to be able to fix it. Taken it to indie Jag garage, another indie garage and they all just scratch their heads, empty and refill the tank, charge me and back the message comes 2000 miles later. It’s awful and I’m at my wits end. Does anyone know if the countdown is for real? Mine says I have 450 miles before the engine won’t start again, is this actually true, because if it is it’s a liberty. How can I turn all that stuff off so I never get the threat again? I’ve wasted do much time and money on this issue I’m thinking of chopping the car in and never touching JLR again. Anyone who knows a garage that knows what they’re doing with a Jag in Worcestershire I’d be interested in knowing about. Nick

I do believe the countdown is real and, although it is a bit much, I understand that it is a legal requirement that was put in place by the EU. This is intended to stop diesel car drivers continuing to drive when their AdBlu system isn't working and thus (in the EU's eyes) polluting the atmosphere with their tailpipe emissions.
The "incorrect diesel exhaust fluid quality detected" message is misleading - it normally means that there is crystallization around the AdBlue injector or some other malfunction of the system and is nothing to do with the AdBlue quality. There are plenty of threads on this forum regarding this issue which can readily be searched for. More needs to be done than simply draining and refilling the AdBlue tank and there do seem to be some dealerships and Indies in the country who understand what needs doing. I guess you need to find one of them, and perhaps someone on this forum can suggest someone.

Just read post #1 on this thread

Hi, thank you for your replies. I have read post #1 but I’m not a very practical sort of person. I wouldn’t understand one end of meter thing from another and don’t want to do a DIY fix as I’m not competent to do so. I just need a professional who’s experienced and trustworthy to take it to.

Hello All;
Resently purchased a Jaguar XE 2.0D R-Sport 163 bhp 2016 Reg with 98 K miles.It had full service history with Jaguar.I was given Engine & gear box 3 month warranty,this was purchased from an independent car dealer.After driving abt 100 miles I had the Amber EML light come up.I topped up Adblue (Redex)[I was in a hurry and the Jaguar dealer was closed].It only took a little(im guessing 200 ml).I presume the tank was full.After about 50 miles of topping up Adblue i got the warning-"Incorrect Diesel Exhaust quality detected",after it changed to "No engine restarts in 515 miles,Incorrect Diesel Exhaust Fluid Quality Detected".
Having driven more miles.I jacked up the car and checked the Adblue injector-This was not spraying at all when the engine is running.There was black deposits on the injector & where it connects(i cleaned both) ,then started the car again,still no spray from the adblue injector.The warning changed to-"No engine restarts in 251miles.Diesel Exhaust Fluid Dosing Malfunction"(im guessing because i started the engine with the adblue injector disconnected) after this I took the car on a 25 mile Motorway drive,mostly with the engine RPM @ abt 3000RPM+/-
N.B- there was the following codes before i attempted anything-P20ee,P049b

I have drained the adblue tank & refilled it.Took the adblue injector out,cleaned it & checked the 2 pins for continuity ,it has continuity,so im inclined to believe that the adblue injector is OK.
started the car without the adblue injector just to check no adblue comming out of pipe,so as the connectors are ok it still didnt spray adblue,i tried to check the connector in the car itself(not the one in the adblue injector),cant fit the multimetre probe,may be lateron will stick a cable & try!!
Im trying to figure out what options are left

I am suspecting the following;
-Adblue injector is at fault(unlikely now after checking it)
-If Else Adblue pump(IDK about this)but it must have a pump someware!
-NOx sensor at fault
After clearing the codes currently I have the following code-P049B(EGR related)
Any ideas?much appreciated

 

[Fighterpilot]

Possible that the EGR needs cleaning as well.

 

[Bobby]

Possible that the EGR needs cleaning as well.

I think so but this i will have to attempt later.I cant think that adblue injector not spraying is directly related to EGR.My 1st priority is to get out of the xxx miles warning.

 

[Fighterpilot]

This problem of the Adblue fault is most likely caused because the ADblue is allowed to run down and effectively get stronger in the urea element as the water carrier evaporates.This is then detected as incorrect Adblue detected. I top mine up about once a month and always have done. I am now approaching 8 years of ownership with no Adblue faults as it never gets time to concentrate out. If you look at dried Adblue you will see how white the residue is. You will also notice how hard it becomes. As the tank if stuck up against the rear wing, on hot days it will evaporate so much of the water off. Under normal conditions that would be acceptable but as the tank gets to a lower level then it will concentrate. Problems then arise. I have even spoken to people who didn't even know about the Adblue tank. I have used 2x10 litres in 8 nearly years, carefully storing the supply containers at reasonably constant temps so as not to get too heated or cooled and always shake the bottle before use. As I have stated many times I decant approx 2 litres into a Redex Adblue bottle with a valve that avoids overfilling built in.

 

[Fighterpilot]

Regarding your EGR valve, I think that the magic box of electronics throws up the fault after the Adblue fault then the NOx sensor plays up, from other people's reports.

 

[Indianajons]

When you say you refilled the ad blue tank, Bobby, how much did you put in? If it's overfilled at all it'll throw up the errors.

 

[Bobby]

Think I filled till it wouldnt take anymore,but now I have refilled with abt 4L less.What concerns me most at the moment is that the Adblue(DEF)injector is not spraying.

 

[Indianajons]

Not sure whether you'd see the injector spraying when removed as the pump is controlled by the engine management system so may well detect a fault and prevent it operating.

I see your point,thought abt it as well but saw different cars on internet spraying adblue when engine running idle however not an XE.Im running out of options now.My next option is to check the NOx sensor,have seen some posts that the XE has a secondary sensor as well,so not sure if there is 2 NOx sensors!

If you have a meter that can clear the fault and then drive/clear faults as per post #1 you should be ok.

I have attached some pics of my NOx sensor.

In the first picture, I can see that the connecting cable covering is torn or abraded. Could it be that one of the wires inside has also been damaged so the NOX sensor is not working?

 

[exhee]

Thank you for the information provided. I had a lot of issues with this when my car was under warranty and thought it was finally solved a couple of years ago when Jaguar did a thorough check and changed the DEF injector and catalytic converter (at least that is what they say they did)

The incorrect DEF quality message appeared again last week (so two years on).
I took it to my local mechanic who took off the DEF injector and cleaned out the crystals that were filling it up.
He reinstalled it and reset the error messages, but was left with the dosing error message and 500 odd miles to go before no restarts.
He was unsure how to proceed so I took the car home.
After reading this post, I decided to buy a cheap OBD2 meter which I ordered click and collect.
On my way home from picking it up, the error code cleared and has stayed clear.
I had driven about 15-20 miles.
I haven't yet tested if the cheap OBD2 meter would have worked with clearing any messages.

My conclusion (with no Jaguar or other formal information) is that the DEF injector clogs up over time and the engine management system has to increase the dosing to try and keep NOX readings in specification.
Eventually enough DEF can't get through and the DEF quality error is posted.
The DEF injector is cleaned, after which the dosing is not immediately correct, but over the course of those 15-20 miles of driving, the management system adjusts itself and the fault clears.

So just posting to confirm that sometimes this error can be relatively cheap to fix as per the original post scenarios.

Not quite - The error appears on the screen as a fluid QUALITY issue - Once the job has been completed error codes are cleared down using a cheap code reader (even if it shows no codes, use the clear codes function. Once that has been done the error message looks almost identical, except the word Quality changes to DOSING malfunction. From that point onwards the car needs to be driven a few, to 20 miles, and then it will disappear off the screen. So sounds like the mechanic had cleared the codes, just not done the driving bit - which you went on to do..

See this - it will def fix it - Easy job

Remain calm people.

I'll keep this brief (as I can) feel free to ask any questions.

First of all, your Jaguar or Land Rover hasn't got a DEF quality detector. What this message really means is, there is a problem somewhere between your DEF tank, exhaust and ad blue injector.

1. Potential problem No 1.
Have you recently just filled your AdBlue tank?
Your tank has a capacity (XE capacity is 9 litres) if you over fill your tank you could potentially get this error message.
FIX. Remove your rear left wheel and wheel lining to gain access to the bottom of your AdBlue tank. Find the drain hose and drain some out. After this you will need an OBD II meter to reset the message. This won't fix the problem but should change the message to "Diese Exhaust Fluid Dosing Malfunction". After this take the car for a short country road drive, get the engine nice and warm and plug in your OBD II meter again and clear any messages. A short drive later and a few cycles through engine on/off and ignition on/off and you problem should be solved. &#x1f44d-1f3fb;.

2. Potential problem No 2
Your AdBlue might just be old, if its been in the tank for a while it may have just gone bad. If this is the case I won't burn away those nasties in your exhaust, which would cause the NOx sensor in your exhaust to detect high carbon emissions and display this message.
FIX. Remove your rear left wheel and wheel lining to gain access to the bottom of your AdBlue tank. Find the drain hose and drain the AdBlue out. Pour a litre of new AdBlue in to the take and drain that out too, just to give it a nice wash. After this you will need an OBD II meter to reset the message. This won't fix the problem but should change the message to "Diese Exhaust Fluid Dosing Malfunction". After this take the car for a short country road drive, get the engine nice and warm and plug in your OBD II meter again and clean any messages. A short drive later and a few cycles through engine on/off and ignition on/off and you problem should be solved. &#x1f44d-1f3fb;.

3. Possible problem No 3.
Your AdBlue gets injected into your exhaust via the AdBlue injector 😱. Have you ever noticed all the white crystallisation around your DEF cap? You could have the same white crap all over your AdBlue injector nozzle. To find out you'll need a jack and an 8mm socket.
Fix. Jack up your car at the front right wheel as high as you dare. Make sure to get an axle stand under there too, safety first. You'll find your AdBlue injector clamped to the exhaust with just one jubilee style clip. Remove the clip, the AdBlue line and the electrical clip and your injector will come away without a fight. Wash the nozzle (if required) with warm water. I've found that a Lucozade sport bottle works well for this. After this you will need an OBD II meter to reset the message. This won't fix the problem but should change the message to "Diese Exhaust Fluid Dosing Malfunction". After this take the car for a short country road drive, get the engine nice and warm and plug in your OBD II meter again and clean any messages. A short drive later and a few cycles through engine on/off and ignition on/off and you problem should be solved. &#x1f44d-1f3fb;.

4. Possible problem No 4.
NOx sensors. NOx sensors (Or lambada sensors) don't last forever unfortunately, they're about £100 or so and from research last around 7 years or 65,000 miles. Which isn't a lot!!! From research I've seen pictures of their electrical wires plastic sheathing eroded away from vibrating on your under tray. If this has happened and the wires are exposed, unfortunately you need a new one.
FIX. Buy yourself a replacement and swap them like for like. After this you will need an OBD II meter to reset the message. This won't fix the problem but should change the message to "Diese Exhaust Fluid Dosing Malfunction".

A short drive later and a few cycles through engine on/off and ignition on/off and you problem should be solved. &#x1f44d-1f3fb;.

5. Possible problem No 5.
EGR valve. If you have all the tell tail signs of an EGR valve fault (ruff running idle, white smoke out the back, so on.) don't worry you don't need a new one, not just yet. It might just be backed up with carbon.
FIX. You could pay a professional to do a deep carbon clean on your drive, and this would do your car the power of good. Or, if you're brave enough you could remove you EGR valve and give it a good de carbon clean with an aerosol spray. Or you could just spray the same aerosol spray direct in to the air intake of your engine, this will eventually get to your EGR valve and clean it out. After this you will need an OBD II meter to reset the message. This won't fix the problem but should change the message to "Diese Exhaust Fluid Dosing Malfunction". After this take the car for a short country road drive, get the engine nice and warm and plug in your OBD II meter again and clean any messages. A short drive later and a few cycles through engine on/off and ignition on/off and you problem should be solved. &#x1f44d-1f3fb;.

In all of these cases, you've probably noticed that you'll need an OBD II meter. In some cases you might even find that the problem on your car is non existent or no longer existent. But one the ECU gets a sniff of the issue, EU law says that these new Euro6 super eco engines have to remain eco friendly, FOREVER!!!! So the problem HAS to be fixed, weather it's a simple fix or not. Either way, the FIX is with a cheap OBD II meter to clear the baddy message, then take the car for a "drive cycle" this should do it. &#x1f44d-1f3fb;

If you've got any questions on any of these processes, drop me a message. I'll do my upmost to help. Potentially saving you £££££ 😘 Mike.

Will the engine actually stop? or will it go into link mode (I only have 100 miles left)... I drained the tank and refilled it with only 4 L of new addblue, I cleaned the injector and tried to delete the error with an OBD II (basic) but can't find any code? I have no more options, I'm a commuter, I have 100 miles left and tomorrow is bank holiday...

A short drive later and a few cycles through engine on/off and ignition on/off and you problem should be solved. &#x1f44d-1f3fb;.

In all of these cases, you've probably noticed that you'll need an OBD II meter. In some cases you might even find that the problem on your car is non existent or no longer existent. But one the ECU gets a sniff of the issue, EU law says that these new Euro6 super eco engines have to remain eco friendly, FOREVER!!!! So the problem HAS to be fixed, weather it's a simple fix or not. Either way, the FIX is with a cheap OBD II meter to clear the baddy message, then take the car for a "drive cycle" this should do it. &#x1f44d-1f3fb;

If you've got any questions on any of these processes, drop me a message. I'll do my upmost to help. Potentially saving you £££££ 😘 Mike.

Will the engine actually stop? or will it go into link mode (I only have 100 miles left)... I drained the tank and refilled it with only 4 L of new addblue, I cleaned the injector and tried to delete the error with an OBD II (basic) but can't find any code? I have no more options, I'm a commuter, I have 100 miles left and tomorrow is bank holiday...
