The Hidden Costs of DPF Systems: What Manufacturers Don’t Tell You?

[@ruivieira9329]

My A4 2.0 TDI year 2011 has 300.000 km whith zero problems on DPF. People need to have in mind that diesel car is not suitable for everyone.

[@BestCarMods]

well said.

[@dafkatan5459]

But what's your daily driving like? Long? Stop and go city? Makes a difference.

[@BestCarMods]

@@dafkatan5459 as a coincidence, I had a 2009 a4 B8 2.0tdi (you can see videos on the channel). that car when I sold it had 250.000 km and no problems. and for the last 3 years of her life my commute to work was 10 minutes :)

[@ruivieira9329]

@dafkatan5459 both, city and higway. Other points people need to be atention are: respect maintenance service intervals, manufaturer recommended oil, diesel premium and thermostats always working perfectly.

[@christianvik3400]

It is the usage of a car that decides if you can have a diesel car with a dpf. If you only drive a couple of miles/kms a day you should NOT have a diesel powered car. Petrol is much better. I only buy petrol cars.

[@davidvanderklauw]

I know that the DPF is underneath the car. I wonder if a DPF can be designed with a pop-out cartridge that can be put into a DPF regen machine overnight and then put back in.

[@BestCarMods]

Where there is a will, there will be a way. Now technically in a passenger vehicle, engineers have more space limitation than on bigger vehicles. On truck, the dpf is like a cartridge that you remove send to a specialised cleaning company and refit.

[@jimb12312]

It can be modified with a straight pipe through the DPF. Passes visual inspection.

There is a reason why volkswagon used deafeat software.

Running a VW 2.0 TDI. Now at 245.000 km. Oil and filter change every 15.000 km. using Castrol quality oil. Adding a squirt of BellAd. Doing 2 1.400 km nonstop drives each half year a 120 km/h. Exhaust pipe exit is always squeaky clean.

[@damiantuttle1348]

Diesels are yesterday's game, not because of manufacturers but because of ever more stringent emission regulations and soon they're to be phased out all together for private vehicles in europe by 2030 under the M.E.V ruling ... I give up with it all 😢

[@BestCarMods]

that is true. we can say that we are discussing some history.

[@jasperaj1]

I live in a part of the world where no such emissions rule BS exists. Here you can still buy new Diesel vehicles without all the engine breaking crap like EGR, DPF, Ad Blue etc.

[@BestCarMods]

@@jasperaj1 where is this diesel heaven ?

[@jasperaj1]

@BestCarMods South America, Uruguay.

[@BestCarMods]

@@jasperaj1 I was planning of doing a video regarding places where there might be a way to have dpf off legally.

[@pravardhanus]

This is the reason why Maruti Suzuki stopped Diesel engines when BS6 (equivalent to Euro6) was introduced.

[@BestCarMods]

what do you drive ? diesel, petrol or electric ?

[@pravardhanus]

@BestCarMods I drive petrol. I have Maruti Suzuki Alto (2009) and Maruti Suzuki Fronx (2023).

[@BestCarMods]

@@pravardhanus you have escaped the DFP problems. Did Suzuki fit PPF on the 2023 car? petrol particulate filter ?

[@pravardhanus]

@@BestCarMods On the Fronx 1.0L turbo engine with mild hybrid there is a mention of PPF or GPF (Gasoline Particulate Filter) in the user manual. So I bought the 1.2L NA engine.

[@BestCarMods]

@@pravardhanus someone has done his homework :)

[@lavrentievv]

EGR off lowers amount of soot to a minimum. Both for intake and DPF health: switch it off.

[@BestCarMods]

Many remap specialist are saying that you can't have EGR off and DPF on.

[@lavrentievv]

@BestCarMods I've had one tell me I can't have both off. But as an engineer, I'm 95% sure you can. ERG off will naturally have cleaner/less sooty combustion, with more oxygen and heat. So regens are probably not even needed if once in a while you put your foot to the floor.

[@BestCarMods]

@@lavrentievv I have done some research into it, as a fellow engineer, and during active regen the egr is closed to allow clean air + fuel resulting in highest exhaust temp. Now where I think is the disconnect is in the ECU software checks, aka regen inhibitors, where maybe the EGR needs to be showing as operational. For the average tuner, it is easy to just remove all the emission systems with something like a "software hammer", than to be sophisticated enough to do a surgical egr off while DPF is ON. Also they don't have access to the developer software.

[@SuperDirk1965]

So sad to know you hate your children. Only those who hate their children are willing to poison the atmosphere for them. Why do you hate your children so much?

[@lavrentievv]

@@SuperDirk1965 Switching EGR off literally cleans up any fumes apart from harmless amounts of NOx

[@thetruth7633]

People have the wrong driving / ownership habit, all that is actually destroying the add on components on diesels. Short trips, low rpm pulling, eco driving style, cheapest fuel, save on maintenance add that to extended oil intervals. Not just diesels..

[@novicetheaf]

I have a Suzuki swift DDIS 1.3 with DPF and its a very easy car to force regen. Ive no issues with it, just floor it every few weeks and it goes into regeneration mode.

[@CaneBTC]

ofc they do. the only thing that doesnt is 90 degree straight pipes out of hte hood.

[@BestCarMods]

What have I missed?

[@pravardhanus]

Urea or AdBlue ?

[@BestCarMods]

@@pravardhanus that is another can of worms ... sounds like a good topic for a video 😏

[@KarelSmout]

Extra weight being compensated by ever more plastic parts that are heat-cycled with the engine (like belt-tensioners, water-pumps, sensor-housings). Such parts have inherent limited life-span.

[@simplemechanics246]

Yo missed completely the core point. I do not tell it to you, it is bit secret on that industry. Digg way deeper and you will discover it. Soon as you discover it, entire that video basically you can send to dumpster.... I do not say because I wanna bad, just without core you have basically nothing

[@MrEverLeal]

O caminho são os carros eletricos, pq esses carros a combustão novos, são problemáticos, principalmente pra os Brasileiros.

[@BestCarMods]

what is the average temperature in brazil ?

[@MrEverLeal]

@@BestCarMods Depends on the region, North and Northeast between 27º - 42º Celsius and South and South-East between 5º-34º

[@BestCarMods]

@@MrEverLeal the story regarding EV limitations is that the battery does not like high temps or low temps, and in many cases if the outside temps are high you use power to cool it down, and if it is cold it uses power just to stay warm. You reach a point where an EV is good only if you actually do the miles not just keep it parked.

[@MrEverLeal]

@@BestCarMods I understand, but here the BYD Brand is selling a lot, it is in 6th place in sales in just 1 year.
