Did they introduce a new engine oil for the BS6 diesels? Ford used to recommend a mineral oil to promote a low cost of service.

If the oil isn't updated to a low SAPS one, DPF is going to get clogged permanently in no time at all. This clogging with sulfur / ash is NOT going to get regenerated, because it can't be burnt off like soot.

Another website claims the following to be the correct oil grade for Ford DPF diesels:

Ford WSS-M2C934-A
(Extended drain engine oil for vehicles equipped with diesel particulate filter (DPF))

Didn't the first gen Ford Figo have a DPF? My 2010 model had one. Why is this mature technology causing problems now?

I think you are confusing the catalytic converter with the DPF. There is no DPF in older Ford cars. It's only BS6.

Also the reason Ecosport has this issue is because it uses a DPF alone and no SCR. I am not sure there is an LNT like Kia Seltos and Creta which use a DPF + LNT. The Endeavour has a DPF + SCR.

Ford has been having issues with DPF from a long time here in the UK. Here is an article and a forum discussion on them. The main contributing factors for these issues are short distance trips, frequent starting and stopping, high acceleration and deceleration, idling for a long time etc.

https://www.kugaownersclub.co.uk/thr...-issues.15589/

This is what they suggest to follow for the DPF fitted vehicles -

Drive your vehicle, preferably on a main road or motorway, for up to 20 minutes avoiding prolonged idling, but always observing speed limits and road conditions.

Do not switch off the ignition.

Use a lower gear than normal to maintain a higher engine speed during this journey, where appropriate.

My opinion is that either presence or the absence of LNT/SCR will not have any bearing on DPF's performance.

That is because, the LNT/SCR stage is performed after DPF stage.
To elaborate, the SCR Sytem or LNT hardware are fitted downstream (after) the DPF filter.

So now Ford BS6/Euro VI diesels need a new sticker saying "Drive to (let the engine) Live".

FE do get affected during DPF passive regeneration or during aborted attempts owing to lack of consistently higher rpm(highways). Below is my experience with a BS6 diesel( Seltos with a DPF+LNT set up). Just cross posting from another thread.

There is just another observation. I don't have any technical details to provide. In the same stretch of roads in city limits at similar traffic and driving conditions, the car returns different FE at different times, that is at least 15-20% less. This I suspect happens when the system is trying for a passive regeneration and hence more fuel is fed into engine and owing to weak RPMs, it gets aborted. Would like to hear from fellow members on this. I can't think of any other reasons for such inconsistencies in city FE for same road and driving conditions.

Below post was an year ago.

But i've only run 3k kms since using BS6 fuel and have not faced any DPF warnings since then. At the same time, my friend's Seltos had the warning once within 400 kms and his car had run only in city limits during that period and he was on BS6. Each time he had to pay a visit to service centre. He also had three more instances of DPF choking, all during BS 4 and 90% city commute. In fact it's not just the kms covered in city limits that should count, instead the number of hours one spends in city limits. To log 400 kms in city, one could take 35-40 hours or even more depending on the traffic, means more quantity of fuel is burned without passive regeneration.

From my conversations with many other diesel Seltos owners in whats app groups, it's safe to conclude the DPF warnings now are not as frequent as in BS4. And unless the car is running only in city limits, one should be able to run at least 10 k without any DPF warnings and by then car reaches the scheduled service interval and service centre can do a DPF regen then.
Another thread in which DPF issues were discussed
https://www.team-bhp.com/forum/techn...te-filter.html (FAQs about DPF (Diesel Particulate Filter))

Taking into account that Ford also user a similar set up, guess it all boils down to the software that controls the trigger for regeneration. Else it could be faulty/inconsistent sensors that's playing havoc with Ford vehicles. As a practice, I always get my oxygen sensor checked and cleaned whenever I take my car for service irrespective of any DPF warning. I always find the sensor reasonably clogged and could be few days/kms away from triggering a warning.

I have purchased a MY2020 Feb manufactured Aspire Diesel BS6, took delivery last month. Have done around 900 kms yet. I'm getting low FE of around 11-13 in mixed condition along and also feel lack of power in the lower rpms, is this the DPF issue?

[TDCi4Life]

I have mixed feelings on seeing this issue take centre stage. Glad that is being highlighted on an influential platform like Team BHP. Not glad cause it seems to be more widesdpread that I thought.

I acquired the BS6 Ford Aspire 1.5 TDCi in March 2020. The car ran without any issues in the first few months (even with its almost hibernation-like existence during the first lockdown period that followed right after I got the car). After the first 1K inspection, the engine would occassionally start knocking - specifically when on an incline with 4 or 5 people on board, shifting from 3 to 4th gear, post speed of 50kp/h. Any input from the accelerator pedal at that point and I could see the rpm needle stuggle to rise and fall slightly, as the engine would simply fail to respond.

When I took my Aspire to FASS, I explained all above mentioned specific conditions when the isuue would crop up, helping them to replicate the issue. On first attempt, the test driver just took me along with him for the test drive (I had mentioned the pick up issue only cropped up when it was on full load), yet he drove as if we were participating in a drag race. Nothing happened...and he was quick to point out "Sir, where is the issue huh?" I assumed that issue must have rectified itself (wishful thinking) and went back home.

Unfortunately, the issue kept cropping up under the exact circumstances mentioned above. Reported the same with a 2nd complaint to FASS. This time around, they got 5 people to sit in the car (including myself) and the test drive was conducted, only after I lost my cool and senior Service executive had to step in. And voila! the car just wouldn't respond to any throttle input post 2100 rpm/3~4 gear shift the moment we were on a incline.

The car was kept at the service centre and after their investigation, I was informed that it was a software bug that would require a patch. They also performed a manual DPF REGEN. I took the car home as they stated they would have to co-ordinate with Ford's Chennai IT team for the patch. After following up with FASS/dealer for few weeks, I was informed that the Chennai team was unable to find any resolution for the software bug and the issue has been forwarded to Ford Detroit.

Fast forward to present day, although the issue hasn't cropped up in the last few months, inspite of regular follow ups with my dealer/FASS Service head, there is no patch available yet. Silver lining - I managed to get my warranty extended for an additional 2 years, complimentary. This was possible only after the intervention of a very senior executive from another manufacturer, who happens to be an acquiantence of a member of my family.

My Aspire BS6 1.5 Titanium+ (March/2020) had a slightly better FE of 16~18 kmpl in mixed conditions during the initial few months. But it gradually increased over time. Yet, the current FE is around 22kmpl (tankful>100kms top up to full tank). Ideally, your FE should start showing an improvement after the 1st service. If it doesn't, take it seriously, report it to your FASS/dealer and be prepared to log all relevant details and follow-up for the long haul.

Ford must find a way to do away with the DPF by deleting it in the service.
There is no harm in deleting an imminent headache.

I have been watching a lot of videos on 'deleting' being done on US trucks. It would be interesting to find a way to use that here.

DPF isn't an extra feature on the Ford vehicles, it is a requirement to comply with the BS6 norms. Removing them would be illegal.

[Nikhil Paradkar]

It might be a dumb suggestion, if the issue is of DPF, can we try to switch to BS4 exhaust system and eliminate the DPF altogether?

One hindrance I see is for BS6 vehicles the emission norms are strict, so this might make the emissions reading go up in PUC testing.

Are there any other technicalities that I'm missing? Please guide.

The DPF + LNT/SCR system is the major change which was brought in to meet BS6 regulations. These are the systems which make BS6 diesel emissions comparable to those of gasoline.
Hence, deletion of these systems will be unlawful and a punishable offence in my opinion.

First and most important, it will be illegal to tamper with the exhaust system. Presence of soot in the exhaust will easily give away that DPF is not working/removed.

Second, this will not be simple switch of removing few pipes and refitting new ones. Given the host of sensors and their connection with the ECU, you will need to swap a lot of parts. Warranty goes for a toss too.
Expensive and doable. But you need a real skilled mind who knows the system in and out.

How can you switch to BS4 exhaust system on a BS6 car? A car company (or an individual) can never do that legally.

There's no excuse. Ford should fix the system and provide the solution for free of cost. Most of the BS6 cars throwing up the errors are already in warranty period.
