Excellent explanation of dpf issues, which have dogged my Subaru Legacy turbo diesel. Purchased the iCarPro with Carscanneras suggested, but the dpf sensor information is not available, even with the pro version. Presumably this is because it's not supplied by the Subaru ECU. It doesn't seem to be possible to check this type of thing in advance.
Aw that’s disappointing I’ve found it works with anything I have tried. I’m guessing you’ve probably seen this video but just in case you haven’t it may help. It seems to show quite a bit of DPF info on a legacy. th-cam.com/video/jMOgEhUG8ig/w-d-xo.html
Thanks, looking at both videos again I noticed that I hadn't changed the connection profile during setup so the 2010 iso standards were not being used. All good now, thanks for your help.
Hi, its pretty simple. Click on the Dashboard Icon in the menu. Click the Cog Icon Click Add Page Select the Page layout you want Select the Sensor and the format of how you want to display it in each of the Dashboard Sections
Hi, you shouldn’t. As far as I am aware there is no difference in the App I just upgraded to Pro as I felt the developer deserved it. You don’t say where you are from, are you sure your car has a DPF. I believe Euro 5 only became mandatory in UK in 2009. Also is it possible the DPF has been removed and mapped out? It also may be that BMW have buried the info in their native PIDs rather than using the standard OBD2 ones. Though given this guy has done it on a later model I would be surprised if that were the case. th-cam.com/video/rKDogGqxdqU/w-d-xo.htmlsi=kYYyVtYhVUfR9Oau Asking on a BMW forum may get you more specific answers.
You might want to add that every regen leaves behind a little bit of ash which cannot be burnt off. Eventually (North of 100,000k) the DPF becomes clogged with ash which cannot be unblocked with a regen. This is the cause of why regens becoming more frequent as a cars mileage increases. Most buy a new DPF at this point, however, you can actually remove the ash mechanically by removing the DPF and blasting from the rear with a high power jet of water, there are a few companies that provide this service in the UK. Many lorry DPFs are actually designed with this in mind and can be disassembled and cleaned easily with a regular jet wash. All the best.
Hi- thanks for sharing, the minimum ours goes down to currently is 13% of the Trigger value (6% actual soot content) having done 45,000 miles so I hope it will be some time before it needs anything more than the normal Active Regens to get it back to to a reasonable level, as long as we continue to keep an eye on that they are completing successfully.
Hi! - Yes I went for the Pro version too as I thought it was so good and felt the developer deserved the income. I've not explored what the Pro-version gives you extra as I was able to do everything I needed with the free version, so thanks for sharing.
Hello thanks for the vid. I tried to monitor my dpf pairing car scanner with elm327, but the dpf sensors do not give any data. Should I upgrade to car scanner pro?
Thank you for the vid. Very useful! I have a 2013 Toyota Yaris with a DPF and the engine has 130.000km (80.000 miles). I have a problem with the oil level due to very frequent regens (I counted that regens occur every 250-300 km. So the oil level increases at every 2.000 or 3.000 km and a spanner turns on on the dashboard. I visited a TOYOTA dealer last year and they said that the DPF is in a good condition. Three months ago I visited another mechanic because the spanner was on again. He made a forced regen (after that the DPF was at 15%). Also he changed the oil. Now the spanner is on again and the mechanic says that I have to change the oil... This is very confusing and I am kind of desperate. It is simply unaffordable to have an oil change every 3 or 4 months. So my question is: If the DPF is in a good condition, then why does my Yaris regen so often? Could it be a problem on the electronics or the engine management system you refer to in the video? Could we simply adjust somehow the way or frequency that regens occur?
Hi, I can only go on theory here as I don't know the exact set up of the Toyota DPF. The distance between Regens is impacted by journey length, fuel type, weather/temp, driving style etc, I wouldn't say that 250-300 km between regenerations is unusual. You can see in the video that the average distance between regens on the Land Rover Discovery Sport tested is 180 miles (about 290KM) However in my experience, Oil Dilution would only occur if an Active regen isn't allowed to fully complete. This is because the left over diesel, used to carry out the regen, is dumped into the oil sump if the regen is interrupted - for example if you turn off the ignition while a regen is in progress. If the regen completes successfully it shouldn't impact the Oil level / dilution. Your rate of oil dilution would suggest to me that your regens are regularly being interrupted. This is often the case on vehicles that only do short journeys as the Regen doesn;t have the time to complete. This won't necessarily damage the DPF if at some point it is able to complete a full Regen or a Forced Regen to empty it. Are you using an OBD2 reader to know the average distance between Regens already? if not how do you know when a Regen is in progress? My only recommendation is to use a ODB2 reader (as in the video) to keep a constant watch on the DPF trigger level and when you see a regen is going to be triggered / triggered make sure you continue to drive the car (usually 20-525 minutes) until the Regen has fully completed as shown on the ODB2, so making sure the oil is not diluted. Hope that helps.
Thank you so much. I appreciate this information. I purchased this Yaris 2 and a half years ago (Back then it had 90.000km) Since then I have been carefully watching the regenerations just by observance. Two signs that indicate a regeneration has started are (1) instant consumption increases a lot and (2) the rpm increases also, and that is evident when the car is not moving. (The rpm is normally at 800, but when a regen is in progress it goes up to 1.000) Whenever I understand that a regen is in progress, I try not to turn the engine off and if possible to keep driving some kms. It is true that sometimes it is not always possible to do that. But in most cases I continue driving, and once the rpm and consumption are back to normal, then I turn the engine off. Please let me know if something does not sound right to you until know about how I deal with it. It is true that most of my journeys are short and inside the city, but what impresses me is that the frequency of regens seems to be the same when on long trips also. For example in a trip of 1.000 kms, I have noticed at least 3 or 4 regens. I do not know if that is normal. I suppose that it should not regenerate so often when on long trips. I am trying my best following tips I have learned from yt and my mechanics, but still it seems that it is not enough... I have not tried to use additives. If I use them, could I expect that the frequency of the regens will be reduced? If you recommend some specific ones, please give me your suggestions. THANKS A LOT
It really irks me that car manufacturers treat customers like idiots and don't put a simple indication that a regeneration is in progress and it's better not to stop the engine. In my car I more or less know when it's happening (due to the increase in rpm at idle and the smell of a dead cat) but I still don't know when my ducato (which I care about a lot more) is doing it.
I totally agree! I can't think of any reason not to make it clear when an Active Regen is in progress or even when it is due to complete one, so you can plan accordingly. Having filled that gap with the Car Scanner App and VGate OBD2 permanently on the Discovery Sport for nearly 6 months, gives me loads more confidence and reassurance the car is doing what it should and I can adapt to allow it to. That has to be good for the Manufacturer's reputation long term and warranty claims. Though it would give a hit to their income from post-warranty repairs.
Don't know every car does, but Peugeots (presumably same platform DS, Citroen, Vauxhall, Jeep too) turn the rear defrost and side mirror heaters on. You can add an LED and be aware. Saved me a couple times turning off while it's doing its thing.
Found your vid really useful and just picked up the Vgate featured and downloaded the Car Scanner app. Been able to connect to my 2017 transporter fine and able to monitor almost all the parameters apart from DPF soot% and DPF regen type. I noticed your using Car Scanner Pro, do you have to upgrade to be able to use these parameters or am I missing something? Cheers Ben.
Hi, you may have found it already but just in case this thread seems to answer your question allowing you to add custom PID codes to add. www.t6forum.com/threads/vw-t6-custom-pid-codes-for-dpf.33964/

I've got the pro version of the car scanner, I think you can have more graphs open. It was only £5-10!

Car scanner Elm does not seem to support the Nissan Titan XD 5.0 Diesel
Greetings
Is possible to stat a regen with this ?
Or just passively look at the pfone while is regenerates when it needs to?
:))
Thank you
Depending on the make and model of your vehicle the Autel can force a regen. The cheaper one can’t.
Hello thanks for the vid. I tried to monitor my dpf pairing car scanner with elm327, but the dpf sensors do not give any data. Should I upgrade to car scanner pro?
Upgrading to Pro probably wont make a difference.
What vehicle is it? It could be down to the manufacturer.
Toyota Yaris 2013. I also noticed that other sensors do not give data as well. Is there some other obd device or software that could work?

So we can watch the soot level with Icar Bluetooth 3 without paying to car scanner app?
Yes you can use the free version of car scanner app.
I chose to upgrade to pro as I felt the developer deserved the money.
I want to buy Bluetooth 3 instead of 4, since it is cheaper. Is there any difference between the two except for the iOS support?
