Another week, and another fault with the DS. :rolleyes:

On my way into work this morning I'm greeted with:

"No Engine Restarts in 540 miles. Diesel Exhaust Fluid Dosing Malfunction."

Pressed the LRA button in the roof console and the operator was very helpful, to be fair. She was originally going to send the AA out to me but then decided she needed to send a LR Technician out to me. Should be with me by 5pm today.

Worst. Car. Ever.

Hi, we were in the South of France last week (Alps) when I got the Engine warning light come ..... 5 Mins later the following:

'No Engine Restart in 540 miles. Diesel Exhaust Fluid Dosing Malfunction'. :shock:

No problem except I was 600 or so miles from the Euro-tunnel so no way could I get home. :cry:

having phoned the LR assist they sent an AA man out the next morning (to the Lodge we were staying) and after 4 hours of LR software resets and updates he had it cracked and all has been week for the journey home.

What came out of it hough was that Jaguar/LR send 10 dedicated specialists to France for Jul and Aug in the guise of AA, they have Jag/LR laptops with dedicated software for our cars that they take back to England when the summer is over. Sadly the number of breakdowns over the summer make it more cost effective to have them live in France for 2 months than use the dealer network that would not have looked at my car in time for me to get home. While the guy that fixed mine (usually works in London) was great it was worrying that they have sufficient breakdowns to warrant the expense, or worse the network is so bad they wont respond to breakdowns.
Apparently 80% of the breakdowns are as a result, or because of, AdBlue issues/customer ignorance. Most are fixed by software or re-filling. Mine took 15 software resets and a 3 full software uploads to clear the warnings.
Disappointingly the software appears to be very flaky (Ford primarily) and does not load cleanly but..... he did do two software upgrades the car needed that had not been done the week before when it had its first service in the UK... yes it failed 1 week after the dealer service!! Since then it has given about an 8 - 10 MPG improvement!! :cool:
While I am now nervous to keep the car beyond its warranty it just goes to highlight the issues of modern cars and software, the cost of ownership after the warranty runs out will be exponential.

Has anyone else had a breakdown in France this Summer or had the same warning mine had?

As I type this, the LRA Tech is under my car soldering some new wires onto the adblue injector. They had snapped, apparently. :roll:

Mine had been 'played with' (routed wrongly past the heat deflector) which must have been during its only service the week before, but had not been damaged. Interestingly my Tech said you can not solder the cables because it will affect the resistance and the data flow will record an error, it has to be 'clamp' type connected!!

Just shows you cant get a straight answer from anyone!!

Thanks, Barnsh. Was going to suggest you merge the topics.

My Adblue injector cables were soldered today; I saw the gas-powered soldering iron in use. It behaved OK on the way home today but we will see how it fares over the next few weeks.

Interestingly, the LRA Tech said that he also attempted to update the Powertrain Control Module (PCM) but was unable to do so due to a "glitch with the software in the Heating and Ventilation Control Module". Which makes me wonder just how the dealership managed to update the PCM last time it was in the dealers.

So there's another thing for them to attempt to fix when it eventually goes in to the dealership on 18th September, by which time, the car will be approximately 2,000 miles overdue for the oil change service it needs all because my LR dealer can't fit me in before then.

Out for a drive today and "No Engine Restarts in 540 miles. Diesel Exhaust Fluid Dosing Malfunction." pops up out of nowhere. Oh great! - considering its less than a week to Christmas and I'm booked to be the 'taxi' for my 94 year old mother-in-law over the holidays. With luck I should have enough 'miles' to get through the xmas and new year period before my engine locks me out! I immediately head for home, to 'save' miles. I stop for lunch at a local country pub. On re-starting the fault message has cleared!! I'm shown that I have 4225 mls worth of DEF still in the tank.

Now do I trust it? Is LR Assist cover available over Xmas / New Year?

I believe LR Assist work 24 x 7.

In my case, the fault was caused by a snapped wiring loom to the Diesel Exhaust Fluid (DEF) injector. Not massively reassuring for a vehicle designed to spend time off road.

Suggest you press the button in the roof and have a chat with LR Assist to see what they say. They may send somebody out to look at it; they may not. At least you've reported the fault to them.

My 2017 DS HSE LUX just got this message. 7000 miles, had a service at 6000 before being sold.

Diesel exhaust fluid dosing malfunction, no engine restarts in 540 miles. LR engineer came out today and below is his report.

CONCERN RAISED FOR EML/MIL DISPLAYING ON IPC - COMPLETED RELEVANT CHECKS: P2047-13 STORED IN PCM - COMPLETED RELEVANT CHECKS/EXPOSED DEF INJECTOR HARNESS - CONFIRMED VISIBLE SECTION OF HARNESS INTACT - REQUIRES RETAILER ATTENTION FOR FURTHER CHECKS/CORRECT LEVEL OF REPAIR, EITHER WIRING OR DEF INJECTOR FAULT SUSPECTED

I am yet to book it with the dealer as unsure how long they'll take..

Why would you be booking it in to a dealer may I ask?

Surely if LR Assist turned up as you say, they would have had it recovered to a dealer and a loan car supplied there and then. What exactly did LRA say that they were going to do for you, the customer? Are you actually in the UK as an aside?
 
#16 ·
The technician submitted the report to the nearest dealer to me and advised to have it booked in and that they would see his report. I wasn't aware he should've recovered the car and supplied a loan car. According to his report, he checked the message, inspected what he could and based on that wasn't able to fix it so it has to go in..

Was it actually landrover assist or the AA ( they try to use) that turned up?

It was LRA that came (Silver van with LR logo on the sides) but the emailed report came from @aa.com. When I asked about this I was told that AA is handling all communication and was assured that the technician was in fact from LRA.

Hi all,
Here is my experience with this, which may be helpful. I got this message on my MY2017 DS with 40,000km on the clock last Friday, with my son driving, halfway into a 500km trip from Sydney to Guyra on a backroad. See attached photo. It said "No engine restarts in 870km. Diesel exhaust fluid dosing malfunction".
I called the service department at my LR dealership in Sydney, and they advised that the 870km figure would reduce rapidly, and that once it fell to zero I would not be able to restart the engine. Their advice was to park, and they would tow me back to their workshop, the most probable causes being a broken wiring harness or a malfunction of the DEF injector. When I said I was 200km from Sydney, they advised me to call Roadside Assistance instead. However, roadside assistance were not interested as the vehicle had 'not been immobilised' yet.
We decided to press on (really we had not other option) to the next town, Walcha, about 120 km away. While passing through that town I got enough internet connectivity to read through the entries on this thread, and was encouraged to read the one from sodum, who had parked at a pub after getting the message, and returned to his vehicle to find it (the message) gone! I hoped that that would also apply in our case.
At the next town, Armidale, we decided to change drivers for the remainder of the trip without stopping the engine. As I got in though, I absent-mindedly pressed the engine start button, which of course stopped it. Worried that the vehicle might not start again, I quickly pressed it once more and the engine started. To my relief the message had gone. I checked for any warnings under 'Vehicle Information', but there were none. The message has not reappeared, 600km later. So it appears to have been a computer glitch.

Hi Carwhiz ....Sodum here.
Pleased to hear my post gave you a little comfort ...unfortunately, from my experience it will only be temporary. The warnings will keep popping up at regular intervals ...but on the upside, they do continue to reset after stopping and re-starting the engine. I continued driving this way for some 3 months - noticing that my Adblue usage had dropped to zero! The dealer had it in twice and failed to find a fault. I had to 'insist' they look a little harder ...and told them that this forum suggested it was a broken wire to the DEF injector. Sure enough broken wire eventually found!

Hi Sodum,
Thanks for letting me know that the message reappeared in your case. It sounds then as if I should have the issue looked at. There is another reason to take it in - the start/stop works very infrequently (a few times a month) despite being 'fixed' by the provision of a new battery (under warranty) at the last service. It worked for a week after the service and then stopped working.
By the way, when you say that your Adblue usage dropped to zero, I'm intrigued to know how one can gauge the Adblue usage. How do you do that?
Thanks

HI Carwhiz, Please be wary of this situation. DS has several cases where a report or warning will appear, then would appear to be fine BUT. Next thing you know the car won't start or on limp mode. Don't continue to use it, make sure LR dealer, LRA are aware that the original warning came out and what transpired. Take photo that it cleared. Put everything in writing.

It happened to me on a different warning, then next thing I know the car went limp and LR was saying that I drove the car whilst damaged. (Mine was DPF amber light which physically cleared and turned off, days after wth no warning- RED engine warning appeared. What I missed was taking a photo that there was no warning after the whole process of filter system cleared... how would I have known that I needed to do that back then. Anyway, LR doesn't want to honour warranty on our then 8 mos old DS, and wants me to pay service for ÂŁ1700 something, despite the fact that very same car is known to have historical DPF issues (in fact rejected and was in the process of replacement and under extended warranty).

Just keep those photos, they might become handy later on.

Hi Carwhiz ...to check your AdBlue usage (and miles to service) you just need to press the start button WITHOUT pressing the foot brake. Let the car go through it's initial checks then press the 'OK' button on the steering wheel - this will show you additional information not normally displayed. You will see service and DEF information as shown on attached photo. I take regular readings and plot them on a graph to show usage trending.

BTW ...I also have stop/start issues. Like you, it works for around a week after they 'fix' it ...then it stops working again! It's going back in the end of this month to be looked at for the 4th time. They're also going to be fixing a reverberation/vibration issue in the 1200-1500 rpm range (noted elsewhere in this forum) .
