Do you guys not clean DPF's in the USA? In Europe they cost so much money, there are specialized businesses that chemically clean DPF's, and most workshops also know how to do it. Back when I was still working at a shop, we had a mercedes vito van, guy was doing multi-drop delivery so loads of stop and go and idling, he was in the shop once a year for dpf cleaning. The dpf he had on that already had around 50k miles on it actually lasted 3 more years and another 30k before it needed to be replaced, and the cleaning costs about 25-40% of the price of a new dpf depending on what year and model. So doing it once a year you actually save a pretty penny instead of getting a new one everytime it clogs
Diesel powered vehicles are not as common in the US….Some shops have the equipment to do it, but mostly it is done on medium and heavy duty trucks. We would have to send out the DPF to a medium duty shop that has the equipment and then if the check engine light came back on the shop gets to eat all the parts and labor to replace it anyway. In the US the mindset is that you’ll get sued if your attempted cleaning doesn’t fix it forever so everything gets replaced as a unit because the unit comes with a corporate backed warranty. Thanks for sharing and commenting.
@@DadsGarageDiagnosticSpecialist oh... That makes sense. Well, after seeing your video about that GM V8 you programmed a control unit for and then got blamed, I kinda get it 🤦♂️ its so frustrating seeing parts thrown out that you know still have usable lifespan left in them.
I have a ‘19 Silverado 2500 6.6. Has 74k on it, I bought it with 65k, haven’t had it a year yet. Been having a DPF related issue. At first it gave me several different codes, P147B, P0106, P0641, P0406, P2495. It gave me the “Service Emission System”, “Engine Power Resuced”, “Oil Presure Low Turn Truck Off” I was freaking out. I checked oil level, it was good, I changed oil in it two was ago. I checked MAP sensor, it was clogged so cleaned it then reinstalled. I disconnected the batteries and then cleared the codes. Lasted bout a wk and now it has a P2002 code “DPF Low Efficiency”. Is there a way I can do a manual regen and not have to take it into dealership for a service regen? Truck isn’t under warranty and don’t need to waste $400 if I can just park it and Hold gas down and hold to 2500-3k RPMs and do same thing he’ll Do at dealership… My next step is to check air filter and see status of that. Is there a way to pull the actual DPF and clean it and reinstall without having to spend thousands in replacing?
If P2002 is the only code that comes back then I would check for any air leaks under the hood and also check for exhaust leaks. P2002 will usually set if the particulate matter sensor detects excessive soot leaving the DPF….. usually this code means the DPF is internally faulty and cracked. A quick easy test is to hold a white towel over the tail pipe and aggressively rev the engine multiple times…. If the towel turns black the DPF has failed and needs to be replaced. The DPF can be removed and cleaned with special equipment… this is mostly done on medium duty and heavy duty trucks… we never try it on the pickup trucks because of the chance that it won’t fix it and the check engine light will come back on. You will definitely need a scan tool to run a service regeneration and also to check the status of the last regeneration, etc. If regen is needed the truck will self-regen during extended highway driving, but only if the computer determines everything else is ok. Thanks for commenting. Edit: check out some related TSBs… #16-NA-380 and #PIP5468F
You could expect to pay multiple thousands of dollars yes. I don’t have any numbers in front of me at the moment. The majority of the repair cost is the DPF itself, the labor to replace it is fairly low. Thank you.
@@watchmanexpert Yes use high quality fuel and avoid long periods of idle time or lightly putt-ing around too much. Diesel engines with EGR and DPF systems like to be worked hard and kept hot 🔥. It keeps everything nice and clean by burning soot away. The DPF is designed to last about 100k-200k until it becomes clogged with ash that can no longer be burned away. I don’t see them get clogged too often unless it’s a truck that spends a lot of time idling at a job site and then not getting up to highway speeds often enough to keep the DPF hot and clean. Thank you.
It’s kind of a general approximation of the miles the engine may have driven if we were to assume the wheels were turning every moment the engine had ran, which is not true due to people idling at stops, warming up their cars, etc… If we assumed the vehicle averaged 33mph for all the hours the engine has ran, we can make an educated low guess on equivalent miles. This is most useful when calculating run-time and wear on equipment engines that do not use an odometer to monitor distance travelled. In this video I’ve used it to compare engine run time versus actual vehicle miles travelled to estimate the driving habits of the vehicle. Thank you for commenting.
5000 hours multiplied by 33 gives you approximately 165,000 equivalent miles. Not too bad, it means that most of the time your engine has been running the wheels have been turning rather than sitting at a stop idling, which is hard on the engine mechanical parts and emissions systems. Thank you.
Another service regeneration. Duramax P2463 P2459 DPF clogged

78,992 miles / 4,840 hours = about 16 miles per hour.
That thing idles way too much.
It sure does… Truck owned by loggers

Soot can be cleaned…..but embedded ash cannot.
It’s not an “if” rather, a “when” will you be buying a DPF.
Correct. Thank you for commenting.

I coded again today, throwing all of the other codes again now and giving me those msgs on dash again
@@lucasbethune8430 needs to be diagnosed… You will need a scan tool and all that.
I have the same truck, the dealer changed the dpf filter, when I got it back I drove 1 week and then the same problem
Did they re-use the differential pressure sensor? Possible misdiagnosis it would seem.
What codes you do have? Thank you for the comment.
@@DadsGarageDiagnosticSpecialist how much is approx for new def filter ? 5 thousand ?

@@IntegrityBuilders you are welcome
Has anyone tried using the Rislone DPF cleaner
I wouldn’t bother.
Thanks.

145,000 miles / 5,000 hours = 29 miles per hour average.
You're idling too much too.
