The "No Engine Restarts" means once the 45 mile limit is reached you can keep driving but it will not start again once it's shut off. I would get it to the dealer who can diagnose the cause, fix it and reset the warning.
The diesel exhaust filter catches unburned carbon and periodically needs to burn it off the filter by "regenerating". That can happen automatically with periodic 30 minute, higher RPM drives (I will put the trans in manual mode and hold between 2,500-3000 RPMs which allows it to heat up without driving at excessive MPH speeds) and can be facilitated by adding Lucas Oil, Diesel Deep Clean to the fuel tank which will burn cleaner and hotter. It can also be "forced" to happen by a technician with the proper diagnostic tool. It causes the system to inject additional fuel which isn't burned in the combustion chamber but passes into the exhaust system where it burns hot and clears the filter.
The diesel is a wonderful, efficient powerplant but due to required emissions systems they are more sensitive to short in-town trips, low RPM speeds and urea DEF quality. It just means there are a few additional things to stay on top of to keep them running properly.

Very helpful! I just bought a 2016 diesel and got this warning today. 240 miles until no restart.

 

Hi Mancerator, I like to begin by saying “thank you so much” for taking the time to reply to my inquiry.
I stopped drive the car a couple of months ago and it's still showing 45 miles as of now.
I bought this car in Florida even though I live in Richmond, VA but I took the car out of the country.
I brought my car with me overseas, and the dealer over here is not helpful at all they dont even recognize the US warranty.
Right now the car is setting in a mechanic's garage, with some tips and information I can direct the mechanic by telling them what needs to be done step by step and by the way the mechanic, does have the diagnostic tool in their shop.
Any tips and information I can get will save my life.
Thank you again.

The DEF does not stay fresh forever and can go bad. Given the low miles there's a good chance the DEF in your TD6 hasn't been used/refilled and needs to be flushed out and completely replaced. Land Rover uses and recommends AdBlue. The DEF injector nozzle has been known to get gunked up with crystalized urea. Usually just needs to be removed, cleaned and reinstalled. Not sure whether doing these things will clear the code or if that requires a code reader to reset.
Also try searching the European user groups where diesels are a much bigger percentage of Range Rovers.

 

Thank you Mancerator.
I will share these valuable tips with the mechanic.

my issue was solved with a software update from an aftermarket shop here in Scottsdale.

 

Hey DieselD, thanks for the heads up. I haven't gotten the incorrect DEF message but have gotten DPF not performing to spec. I'm also in Scottsdale and mine has been serviced by the dealer on a regular basis so maybe that software update was installed. I would however be interested in knowing who the independent shop is that has the tools and knows how to service Land Rover diesels.
Thanks

 

Where are you currently? The shop will probably need to do a DPF regeneration to start and clear out the DEF and refill.

 

Hi NoExpert,
Unfortunately, the car is in south of Spain. The dealers over here are very hard to deal with I guess; due to the car was purchased in the US..

 

i am in scottsdale. rover tech was the shop that did the work. $200 for the time spent

 

Great, thanks

 

Unfortunately there is no transcontinental warranty that I’m aware of. Electronics you can get away with if it’s a big company (Apple, Microsoft), but cars, I highly doubt it. The car was specifically made for the US market to US emissions for US safety standards and warranted as such.

Bummer you’re all way in Southern Spain, if you weren’t too far from our shop in Poland I’d say bring it by and we’ll get it up and running for you.

Unless you’re Spanish you’ll also get hit with the “foreigner tax” in Spain. I got raped for a cheap tire in Barcelona, but mi espanol es muy poco and I needed a tire on New Year’s Day thanks to the guy who failed at breaking into the car and stabbed the tire instead.

 

oh man! Poland, how nice. I wish I could drive it up there.

 

NoExpert, do you have a shop for LR?
I see that you go by "NoExpert" but I think you are ONE.

 

I’m a mechanic at an independent LR shop near Poznan.

I have gone by NoExpert since 2002 and as I’m continually learning I definitely do not consider myself an expert.

Hi NoExpert,
Is there a reliable manual I can purchase that shows or guide my mechanic, a kind of step by step to fix these two problems?
Thank you

 

JLR Topix subscription would be your best bet for what you want to do.

happened again. Got the non-start message for incorrect DEF. Independent shop that did it says all they can do is drain the DEF that is in it, fill it, reset the warning and try a software update again. Anyone else have the reoccurence after getting the message deleted?

 

yeah, the patch to clear that doesn't last all that long .. the dealer said the catalytic converter needed to be replaced, i flipped out, but, it was covered under warranty ...

 

update, just got the vehicle from the shop. they drained the DEF tank, refilled and cleared the codes. They did say the fluid smelled worse than it should. I think it has been in for 5k miles or so. Interesting that my start/stop function was not working just before the DEF message and now that fault for the DEF is cleared, that function is back. Wonder where that connection is. Will go by the dealer to query them on updates, etc

 

Mine does the same thing- after I clear the engine fault codes, the auto stop-start functions again for a while. It’s an annoying “feature.” Now that I think about it, there are several conditions that need to be met for stop-start to work (battery charged, engine up to temperature, steering not at extreme angle, etc). I think there must be something related to the emissions system that after some time is throwing a code at the computer, preventing the feature from working.

 

The DEF fluid needs to be drained and DEF injector removed and cleaned. Then the SCR Replenishment process needs to be initiated.
This can be done by any mechanic who has a decent scanner.

Here is a technical bulletin on trying to resolve this issue.

If the DEF tank is overfilled you will get this issue also.
When overfilled the system loses the ability to vent the tank so the pump cannot function.

 

Hi Bgh13rr and thank you,
the information provided is highly appreciated.

 

Update:

the car was just parked in the garage for several months, I started the engine yesterday and a different message on the dashboard instead of the previous “No Engine Restarts in XXmiles. Incorrect Diesel Exhaust Fluid Quality Detected ” it is now “No Engine Restarts in 55miles. Diesel Exhaust Fluid DOSING MALFUNCTION”.

The mechanic suggested to clear all messages and see if it will fix the problem. Can this be possible?

 

I would clear the code and change the DEF fluid.

 

Thank you

 

OK, I just took my RR sport to the dealer to have the same DEF quality warning error fixed. Second time this has happened. $760 each time to drain the DEF refill it with adBlue and run the regen procedure (basically drive the car on the highway for a bit) and clear the error code. The pdf above looks easy enough to follow. What diagnostic tool do you recommend I buy. Is there anyway to disable the DEF quality sensor?

 

Check on Autel. This is a great scanner that I've been using for a long time. I'm a long time Land Rover owner and the scanner payed for itself after a couple of years.
There are subscriptions needed if you get a newer model that not on the scanner but if you keep it up to date until it expires you basically have thru the last update with
the cars for the model years. I'm currently using a MS906BT. This model uses a blue tooth dongle to communicate with the scanner. New they are around $1200.
I've seen used ones for around $800. But since this is my own scanner for long time investment I bought it new.

Good luck. Scanner also helps if you are doing your own services also.

 

Countdown is back again. Tonight I am draining my DEF tank, cleaning the white crud out of the DEF injector, saving a sample of DEF to be tested, even though visually it is perfectly clear. Then I’m going to purge the DEF line and run the inducement test procedure. I looked inside the DEF injector port and the baffles look clean inside the exhaust. I wish my borescope fit inside the port to see the “brick” for inspection.
I am trying something drastic with the SDD software to reinstall the vehicle as-built and calibration software. I think this is like a factory reset of the ECU. Then I am prepared to try the procedures from some of the exhaust related TOPIX TSBs I found here: 2016 Land Rover Range Rover Engine Technical Service Bulletins

 

Hey Greasy. My DEF injector was cruded up like yours too. I cleaned it but also got an aftermarket injector for $79. Looks and feels heavy like the original Bosch. I'm determined to run the tank dry before having to drain it...Then figure out how to extend the tube for future draining...or hack the sensors. Which DEF tester are you going try? I see cheapish refractometers out there and wonder how effective they really are.

I was having buyer's remorse after reading your initial reply about the Mongoose, and it's $. Not feeling so bad now after reading the fun you have with it tho. The IIDtool BT is super convenient for sure, especially with an iPad. Super happy with the support from those guys too. May endup getting a Mongoose setup anyways to see other JLR V16x functionality. Not needing to make this an additional hobby tho. My '95 LWB does that.

Here's the new added Menu items with the tool update.
(sorry about the refections...)

Weird how it says overfilled, but the console shows less than 100%, down in the 70's% now. Ignoring that...will recheck soon. Love the "Remove 3.0L Then Re-check!" Get right on that...

After the reset, this:

Those features in your tool look pretty good. I don’t think you have the DEF air purge or pattern test, do you? This helped me after draining and refilling the DEF, to confirm the injector is working fine. Here’s the spray pattern after cleaning.

And I ordered this Jegs DEF tester tool from the Walmart online store (sold from a 3rd party), shipped for $26:

 

I really messed up…
While running the update “Configure existing module - Powertrain control module” the SDD program had an error, and stopped updating the car’s computer files mid-way. I don’t know if this is something I did (I’m using a battery charger, not a “maintainer”) or just typical computer glitches.
Now, the car won’t start. It makes sounds that it never made like various solenoids and actuators operating, but otherwise unresponsive.
Taking drastic measures to download the entire “Combined as-built and calibration file update” through the SDD program, but their servers are so slow. It’s estimating 10 hours to download the files. This has been running overnight and only 20% complete. I’m hard-wired to my gigabit FIOS now, but it’s not much faster than the laptop’s ancient Wi-Fi. I’ll keep you posted.

 

Seriously, that is messed up! Good luck and let me know how that turns out. Note to self, "think twice about running 'Configure existing module - Powertrain control module'!".

My DEF tester looks similar. Need to go test a full carton to test the tester. So far the DEF doom warnings have not come back....300+ miles and counting.

I had a portable Jump Start attached to my car when I used the IIDtool.

 

You are seriously adventurous taking the car on camping trip and towing a trailer after it has misbehaved so oddly. Good for you. From you previous posts I didn't realize you were also a Master RR Tech and knew how to configure the firmware to get the engine started first time from a virgin state. My deepest respect for your knowledge in that field. You are an asset to the forum and need better status than just "Registered."

I too believe it is not an actual DEF quality issue, but a sensor issue, or a bug/feature in the firmware to cause so much strife and a revenue stream to the dealerships. Ridiculous also that so many extraneous DEF issues like 'OVERFILLING', 'DEF Level Low', 'Invalid DEF Quality Detected', etc. can disable an otherwise competent vehicle. I mentioned above somewhere that I replaced the DEF injector with a Non-Bosch one ( $79 on Amazon) and am not getting errors currently...but time will tell. I got other irons in the fire but will revisit this issue again soon. Ive not sat down with my IIDTool BT to see the NOx sensor levels, if even possible with it, hoping it is tho. I'll update with my findings too.

BTW, are you removing the shroud around the tank to drain fluid each time, or have you rigged it somehow to access that drain tube? I'm not going there if at all possible to check any fluid quality already added to the system. I never believed the fluid would/could be bad, just like I never believed the Jab would protect.

 

From you previous posts I didn't realize you were also a Master RR Tech and knew how to configure the firmware to get the engine started first time from a virgin state.

I certainly don’t want to overstate my level of expertise. I was a diesel tech only for about a year and a half after college, not specializing in any one brand, before getting a job in the engineering field. Those days are gone forever, when a mechanical fuel pump did all the engine control. My success in reprogramming the Range Rover PCM has come from A LOT of trial and error. This is all new ground for me, but I am glad to see this community of support and I’m happy to share what I learn.
It really is a shame such a good car can be immobilized from such finicky software settings, so I am trying to learn more about the computer remapping or chip tuning systems. This may be too deep a rabbit hole to venture into, but my inquisitive brain and stubborn, can’t-quit mindset are sending me there. Since the way technology is headed only means more computers running our world, it is a good investment to learn this stuff. It’s not like we can trust the stealership or the gov’t to take care of us.

 

I have a 2016 Range Rover Sport Diesel V6, with low 16,000 miles, about 6 months ago “Exhaust Filter Full Visit Dealer” warning message appeared on my dashboard, I was told that if I take it for a long drive the warning will go away unfortunately, I am staying in a very small town and only had the chance to drive it for a short distance trips. Now, I am getting two warnings the first one says: “No Engine Restarts in 45miles. Incorrect Diesel Exhaust Fluid Quality Detected” and the second one says “Exhaust Filter Full Visit Dealer” I only have 45 miles left and after that the car won't start, does anyone know what needs to be done.. Thank you View attachment 298759 View attachment 298760

Hello . I had the same issue with my Range Rover. Thanks to wonderful people who shared their experiences and tips to solve the issues. I drove on highway for 15 minutes, and the issue was solved. Warning just gone and till now no issues. I guess I didn't drive for long time in summer, ( driving my summer car ) that is why def was not heated properly causing problems. I just wanted to share my experience so that someone else could try the same. Thanks.

 

Hello guys. My 2016 RR just turned into a nightmare... Since Oct 18th, it has had "No engine restart in XXX miles. Incorrect DEF quality detected" 3 times. Basically the past month I have been driving my friend's car or just staying at home... I am not sure if the first problem is caused by a 'premium diesel' when I was on a road trip in north Michigan? But interestingly, just after that tank of premium diesel, the error started to show up. So I have to change my plan to head to fox valley. They replaced my injector. Then 2 days later, when I was driving past Chicago, the same error showed up again. At least I was near home at the time. So I waited 3 weeks to get an inspection and another week to get it done (mostly due to staff shortage etc and also a suspension silencer issue). And I picked it up last Monday. On Wed the same week, the same thing happened again when I was trying to pick up someone from O Hare. I tried a local European car shop and they could not reset the ''no engine restart' but filled some AdBlue for me. Then, when I was on the way to the dealer the third time before they close, the error magically disappear... I mean, at this stage, I am thinking of selling the car. Do you guys think this kind of error will keep showing up? And should I just sell it and get a German SUV instead? The used car market is back to normal now. Could not sell it much but also can get a decent one at a good price too. Any suggestions or thoughts will be greatly appreciated.

 

Sorry to hear that you are going through this too.
You said “Premium diesel,” but I want to clarify my issues began when adding premium diesel exhaust fluid “DEF”. I think that’s what you meant too.
I have decided to get out while I can. My problems seem to have gone away for a while, so I will be looking to sell/trade it in. I tend to fall into a false sense of security that the issue is solved, now that a couple months have passed trouble-free, but I was burned before, and don’t have the nerve to go through another round of it.
I honestly do feel that this issue has more to do with brand/type of DEF than we have been led to believe. And hearing that your issue has cleared up right after adding AdBlue might give credence to this. It should run on any certified DEF you would hope, but this seems to be an overly sensitive system design, and it’s not likely JLR engineering is going to put any time into releasing another update at this point. I will add here that my dealer drained my DEF tank, added their AdBlue, but the issue returned eventually.
I’m currently having good luck on the cheap brand DEF. The less fancy the package, the better. In my opinion, testing the DEF is not conclusive to diagnose whether your DEF is to blame; they all seem to pass the DEF quality testers. More trial and error testing needs to be done. I’m not ready to state that brands X, Y, and Z are compatible. IF the DEF was the only factor this could be manageable; the problem is you have to ensure the DEF injector is cleaned and operating properly, the car’s software is updated, and you would need to have the patience to repeat the issue using that suspect type of “premium DEF” to prove that is the only variable that makes the problem return again. And for that, like I said, I don’t have it in me.
