Driving home tonight and the car went into limp mode. Phoned LR Assist - they dispatched the AA, AA turn up and run a diagnostic check which shows a DPF fault. Fault cleared, car working again, will chase LR for a replacement tomorrow.
In the interests of objectivity, I'd say that over-simplifies the issue somewhat. Mercedes' "current generation" of engines include eleven that were tested by Emissions Analytics and 8 of these clearly got though their NOx emissions approval process using "questionable" means. None of these cars should produce any more than 80 mg / km of NO and NO2 but more than half of them exceed the limit by 400%. If these Mercedes cars are using moderate amounts of urea solution, giving good mpg and don't suffer from diesel dilution caused by post injection, it's not necessarily because Mercedes know what they are doing. It's more likely to be because their nitrogen oxides reduction system isn't getting in the way of the various carbon oxidation processes.Henning said:Incorrect. Mercedes have zero problems even with their "current generation" engines. It's simple - they know what they are doing and JLR don't.
I got your point, Henning, I just don't think it covered enough of the terrain. Judging by the extraordinarily high NOx output exposed by the Equa RDE tests, it is not inconceivable that Mercedes used the acoustic function on board the Bosch EDC17 in some or all of those Mercedes-Benz cars to obtain much lower NOx figures than the cars can achieve on the road. That puts owners at risk of the effects of a recall if their car is included wthin the 3,000,000 vehicles that MB are proposing to modify. (NY Times)Henning said:as, in fact, responding to the following statement that was made:
"With the exception of some "next generation" diesels now being manufactured by Mercedes, none of the 2017-2108 diesels are suitable for you."
and was not implying that Mercedes or, for that matter, any others have zero problems with their emissions.
My point was, and this is confirmed by PhilMabbots17 there are absolutely no problems with the DPF. There are, to the best of my knowledge (and I am very directly involved), no cases of people like Rachael running into problems and no cases of owners rejecting the Mercedes vehicles for this reason as has been the case with DS owners.
The engine's compact dimensions allow even more flexibility in adapting to different vehicle models. The interfaces between drive unit and vehicle have been standardised across all model series. More especially, all the elements of the exhaust aftertreatment system are now configured directly on the engine itself and no longer on the vehicle.
Exhaust emissions: all set for the future
The new diesel engine is designed to meet future emissions legislation (RDE - Real Driving Emissions). In contrast to the current NEDC measurement cycle, the WLTP (Worldwide harmonized Light vehicles Test Procedure) cycle is aimed at ensuring that the figures for standard and real-world consumption are close together in future. In addition, it is planned in Europe to introduce a measuring procedure for Real Driving Emissions (RDE). This, too, is actively supported by Mercedes-Benz.
All components of relevance for efficient emissions reduction are installed directly on the engine. Supported by insulation measures and improved catalyst coatings, there is absolutely no need for engine temperature management during cold starting or at low load. In addition to the advantages in terms of emissions, this results in fuel savings, especially on short journeys. Thanks to the near-engine configuration, exhaust aftertreatment has a low heat loss and optimal operating conditions
Multiway exhaust gas recirculation
The new engine is equipped with multiway exhaust gas recirculation (EGR). This combines cooled high-pressure and low-pressure EGR. It makes it possible to significantly further reduce the untreated emissions from the engine across the entire engine map, with the centre of combustion being optimised for fuel economy.
The exhaust gas from the turbocharger is sent first to a diesel oxidation catalyst. It next passes the downdraft mixer, in which AdBlue® is added by means of a water-cooled dosing module. Thanks to a specially developed mixing area, the AdBlue® evaporates over the shortest possible distance in the exhaust gas stream and is distributed very uniformly on the surface of the downstream sDPF (particulate filter with coating to reduce nitrogen oxides). Positioned behind the sDPF is an SCR catalyst for further catalytic reduction of the nitrogen oxides. Only then does the treated exhaust gas enter the exhaust system
You could try rejecting it ?sparky1 said:hi ,
can anyone help with any advise , my car is in JLR and they are telling me its my fault that the dpf is full and that its not under guarantee due to the type of journeys i do, they are asking for over £1700 to correct it I'm absolutely devastated and and can't believe it I've had the car 2 yrs and its done 13000 mls i have a maintenance policy with my lease company , but they are saying its between me and JLR,
i was never told prior to leasing that it had to be driven in such a particular way ,and don't fell I've done anything neglectful , i drive it the same way I've driven all my cars , sometimes short journeys sometimes long etc,
HiPinkdawn said:My DS is MY18 build and just a year old
Have had no issue with it till a few days ago, all of a sudden the car went into limp mode and the dash's said DPF is full! Then my diesel gauge dropped from 50% to 30%
Called roadside assist and they towed the car
The service team in Australia has been soo busy they haven't even looked at my car
Has this happen to anyone else
No pre warning to say the particulate is almost full and to drive for 20min at above 60km
I should add JLR contacted me a month ago for a 'software' update and I took my car in 3 weeks ago to have this done
Maybe there is a bug in the new software ?

I have merged your thread to the DPF thread if you read upwards , you may find some helpful background info.
It has been seen before where the light goes almost straight to red, it is known by JLR that sometimes the only warning you get is 2.1 seconds.
Yes that's exactly what they are doing m but it is incorrect , your handbook says you should get an orange light to warn you, you didn't , therefor the car is defective , you had no opportunity to clear the DPF.Pinkdawn said:Thanks BarnshBarnsh said:HiPinkdawn said:My DS is MY18 build and just a year old

I have had a read of thread and I'm not liking the fate of my car
So in short JLR knows and just blames the drivers driving style
Ahhh! Makes sense nowBarnsh said:Main thing to ask them was
1. Why you saw no warning , don't take any excuses the handbook says it will warn you.
2. Why all of a sudden has this defect arisen when you have had no issue for the previous xxxx miles and your driving style hasn't changed.
3. Have they checked the SSM 73697 above can they say you do not have a DPF with the FB marking on it.
4. Have they done a full l test including leak test on the exhaust / SCRF system ( if it leaks it doesn't work properly.
That should do for starters.
bjm said:As well as the dpf problem I have loads of other issues. My biggest issue right now is getting JLR to admit the car is a lemonjulzmd said:I am very interested in your case. I have the same exact problem. The dealer replacd my DPF twice. They said it is a common problem and they are waiting for JLR for the software update.bjm said:We"very tried to get a solicitor to look at the case for us but have been unable to find one in our town who will take them on. Most either claim conflict of interest as they obviously have Tues with the dealer or don't have anyone who are trained in consumer Law.
I guess that is the drawback of taking on one of the biggest dealers in a small town...
Yes the Financial Ombudsman is our last resort. I will be calling them today. We will also be putting in another call to the finance company today with the hope that we might get into someone a little more sympathetic to our cause.
Back to the solicitor and copy in the ACCCbjm said:Our solicitor served the dealer with a legal rejection letter. The dealer called us in for meeting and asked would we consider any other product they sell as a trade. Our response to this is that we have already been down that road and we are not interested in trading our faulty vehicle, we strongly believe that we should either receive a refund or replacement vehicle. Each time they have tried this in the past they have offered us a generous trade in but the minimum spend we have been offered is $10k changeover for a (newer) lower spec vehicle. They also suggested that there is no scope for negotiation with JLR if there are no open cases on the vehicle.
We booked the vehicle in and took it back to the workshop for the 13th time. At the same time we sent a letter to both the dealer and to JLR saying we don't want the car back. We have informed them that we are not satisfied with the quality for a premium luxury vehicle and would not have purchased it had we known it would have this many problems. We have also raised some concerns about the safety aspect of some of the faults.
Unfortunately JLR have responded by saying "We apologise that your vehicle has not lived up to your expectations and your experience being disappointing.
We are aware your vehicle is currently at XYZ Land Rover and will liaise with the service department is establishing a suitable outcome for yourself as well as repairing your vehicle under warranty.".
I am driving their loan car at present and was informed yesterday that they are waiting for parts to repair...
