Fixed it

Firstly thanks to everyone who has contributed to this thread, without you I would not have dared to do this.

1) Bought £9.99 a "Torque Pro" OBD reader - Torque Pro Android OBD Bluetooth Fault Scanner/Diagnostic Code Reader : Amazon.co.uk: Automotive
2) Installed the free version of "Car Scanner ELM OBD2" from google play. Currently 5 Million downloads
3) Several faults showed so cleared them all. As others said, then got "Diesel Exhaust Fluid Dosing Malfunction". After a 15 mile drive this cleared.


For info I think the app is more important than the scanner. Initially I used "Torque Lite" by Ian Hawkins as this has 10 Million downloads and is mentioned on many sites. For me it didnt show any errors.
Also note that after clearing, I drove for several days about 5 miles each time, say a total of 30 miles and the Dosing error did not clear. It seems like it has to be a single 15 miles journey.
Had my XE for a year and this has happened 3 times. Each time it was when it had rained heavily so perhaps water spary from the road is getting into the sensor. Once the warning comes on, don't believe it will never go off by itself, no matter if you add more add blue.

Good luck everyone in clearing this annoying problem.

Hi, just bought an XE 180 R Sport and got this dreaded message on the way home from the dealers. I’ve plugged in OBD reader, brought up about 5 fault codes, cleared them all and dosing malfunction warning popped up. Thought I was quids in and just needed do a drive, so unplugged OBD locked all the car up popped inside and then went back started the car and did the drive, then incorrect DEF message then reappeared after about 7 miles.
Was wondering does the drive need to be straight after clearing codes so ignition isn’t turned off between the clearing and the drive if that makes sense?

First, you need to sort out this issue somehow, if mileage count down to zero than apparently car won't start. Unless you want to wait and prove anyone who sustain this theory that is wrong and actually car will start.
Secondly, if you just bought the car I suggest that you take back to dealer to sort it out.
Third point, just cleaning the codes don't sort the problem, can be a cloged adblue injector what need to be removed, cleaned and after you can delete the codes and drive for a while. I think car need a driving cycle what is at least 15min of driving.

 

[Wolfie1]

It doesnt start, have had many recovered in to work with this

In 7 years of driving and keeping the Adblue tank topped up I have never had any issues ( BOOOOOOM that will cobble it all having said that.)

This is what is commonly known as "The kiss of death" in trade! 😂🤣

 

[Fighterpilot]

It's interesting that today I topped up my carefully stored and opened bulk bottle to top up my smaller "tool bottle" It is 2 years old now and I was considering dumping it. On the side was a table of months that it can be stored ant at what temperature. 36 months being the longest at 7c but around 24 months if just kept in a cool place around 15c. As I keep mine under the stairs away from sunlight and much heat may explain why it remains OK.(💀 kiss of death)

 

[Screwy1]

My 2015 xe has been back to Jag dealership 7 times over the last 18 months with the DEF quality error message. The message came up again the other day 5 months since the car was last in and supposedly fixed. I have to admit after paying for the first repair my dealership have covered the cost of all work since until this time where they now want to charge just under a grand to replace the NOx sensor. My question is can anyone recommend where to purchase a new sensor from so I can change myself? Thanks

 

[Cp001]

I've been into a specialist for a clean of the adblu system, 7 months trouble free until same DEF alarm, then 515 miles until no engine start. Topped up and then fine for 1k,same message so topped up again until brimmed. Went to jlr where the alarm maracasly cleared, checked over for free as no fault but reappearance within 100 miles. NOX sensor cleaned at an expense but reappearance again within 92 miles! Have bitten the bullet and had the NOX sensor replaced, hopefully cured but will see as I have only done 50 miles since. 2015 xe r sport tdi

 

[JiggyJag]

Possibly clean adblue injector if message comes back

 

[Sagekajq]

hello I have a Jaguar Xe. Before 2 weeks i had problem with incorrect Exhaus fluid quality detected. After changed new adblue in a garage. Then came new message dosing malfunktion. After that garge said must DEF pump change it. That cost ca 1300 Fr in emil Frey Switzerland. Already changed it with 1350 Fr.
But now that error message come again. Incorrect diesel exhaust fluid quality detected.
What is the problem now? What can i do? Today i must drive to holiday 7-8 hours. But i cancelled now. Tomorrow i will go to the garage again.

anyone help me plz

Sagekajq - this is mostly likely a sensor malfunction. You can buy a cheap obdii reader and reset it yourself (details in this thread) or most garages should be able to do it. Try that first before doing any expensive repairs.

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". 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;.

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.

Tried all of these with help of a friendly mechanic but nothing works. A yin know of anyone in Glasgow area that could do full diagnostic without bankrupting me?

 

[Fighterpilot]

Try a full tank drain and refill. You may also need to look at the Nox sensor. I am repeating here but I top mine up about every 4 weeks (have done since I got it) and so far no problems.

 

[foxy66]

Not all OBD readers will read every car make and if they do some will not do all codes. That was my dilema in looking to buy one last week. I have seen one that states it is suitable for Jaguar, a Vident iAuto 702 Pro on Ebay. The sellers are in my opinion all the same outfit based in China (returns to China only) sold from Leicester or Dunstable @ £135 ish . The fact that returns only to China put me of completely. Machine Mart do some at inflated prices, but I am not aware if they clear Jaguar fault codes.

Hi Fighterpilot
Under Ebay rules any item has to be returned to the location that it is listed in the sellers description, i.e. if they say location Leicester then it has to be returned there. Otherwise complain to Ebay and you will find they will authorise the item to be returned to the Uk location, I had a similar problem and Ebay instructed the seller to have the item to be returned to the UK Location listed on the sellers listing, Hope this helps.

Thanks for that Foxy66 I didn't know that.

 

[Micksa]

So I got this problem (again) this week. Went to my usual mechanic, he did the same as last year, cleaned the injector and tried to reset the error without success (worked last year). I booked it to go into jaguar on Wednesday but had to drive to my best mates wedding in Gretna green today. Roughly 75 miles each way. 30 minutes into my journey home there’s a big puff of smoke from the exhaust and the error disappears. I think the short journeys I’ve been doing with the car running eco mode is just clogging the injector and the exhaust. Get the injector cleaned and get the car a good long run on the motorway before you start forking out money you don’t need 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
what I am thinking of doing next-
-Drain few Literes of Adblue(maybe 4-5L) [my model Adblue tank is 9 L capacity]by removing the left rear wheel+guard,then by finding the drain pipe(have seen a video about this on youtube).As i may have mistakenly overfilled the tank as not knowing what the previous owner filled.Mind you its my 1st Jaguar & its been a pain at the moment.

I am suspecting the following;
-Adblue injector is at fault
-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

 

[Indianajons]

I think overfilling the tank may prevent injector from operating, so drain tank, check injector and its aperture are clear of crystals, clear codes and drive 20 miles at speed
