I have been driving a Fiat 500 multijet (a turbo diesel engine) 95 for 10 years (100.000 km) and had no problems with DPF. But I had many problems with clogged intake system, EGR and obviousely some pipes managing tubo etc.At allready 60.000 km the car started to lose power. Before it has made up to 190 + km/h on the highway and it reduced down to hardly achieved 180. On the other hand the preformances overall become poorer and the economy has worsened for a liter/100 km. I was dealing and banging my hed with this problem for more than 3 years surching for causes and sollutions about what is going on at all. First advice was the DPF. So I went to the dealer service and told them about the poor performances and what I think causes them (DPF). They made all the diagnostics and had found nothing and the DPF was passable OK. They adviced me, it may be the time to change the car?! So, I was having investigated the web and ytube for years and had discovered the problems with clogged intake manifolds, egrs etc. I started to search for a shop where they'd clean it up for me, but had only find it after another year. It was a diesel specialist Burja near Kamnik (Slovenia - there I live). So we agreed there is like 8 hours of labor and material involved - to espect arround 800 EUR bill. But the car was never finished. It was allways something else in addition, some lights went on and some problems occured. The car had been taken from this shop to turbo specialist and back and there again... After a month and a half I finaly reciaved the call the car is fixed. Apparently they had cleaned a lot more stuff, replaced the turbo and god knows what. The bill was 1.800 EUR. What ever it was - it had nothing to do with DPF. The car was running great and fast since, but due to my long wish for a sportier car, I have got myself a Suzuki Swift sport, because they had just abbandoned the production from 2024 on due to emmision regulations and later I would have problems with getting one in good condition and low mileage. But the fact is that Suzuki sport 23 is an GDI turbo engine with EGR and particular filter which is going to cause me headache in the future too, because considering of all I have lerned till now, there isn't a simple and cheap way to clean that stuff out, espechially if your itake manifold is located ad the back of the engine. From everything I learned, spraying is useless. Since I haven't sold my 500 yet, I realy consider of selling Swift and keeping the 500. Fact is they both are great cars - but due to technology prone to cause headache. What do you think?
Is this different from the catalytic converter on a petrol engine? Catalytic converters are quite reliable on petrols. I refuse to buy a diesel just because of all the associated problems with DPF's.
Yes, it is an additional filter on the exhaust, but it should be less problematic than the diesel particulate filter. So, there shouldn't be any problem in regular driving conditions 👍
Ive got one in my vauxhall astra 2021. It's an absolute nightmare. If theyre installing them to reduce emmisions, but the car is constantly trying to clean the filter, im burning through petrol like nothing ive seen before so it DOESNT help emmisions, it makes it worse. It's ridiculous. I wish i'd have known what i was buying
GPF's are a big problem on MY2019 Porsche Cayman and Boxsters, they are incorporated into the cat and not covered under the extended warranty and are costing owners £7500 - £9000 to replace.
GPFs are no bother at all. They are passive, so they don't use fuel to work, in fact they work on lift off of the throttle. If you want to clean one, and usually there's no need, accelerate a car that's already warmed up to normal operating temp, and lift off the throttle and let the car travel on no throttle. But really there's no problem with them. DPFs are a different story. 😄
Tell that to the newest kia sportage 1.6 petrol owners , total nightmare to try and regenerate these filters , and the way you described is not Kia's recommended procedure to clear a gpf/ppf filter requiring a regeneration , that's how far behind the times they are .
Can you just remove it and trick the computer to make it believe it's still there?? If you live somewhere where they put a sensor in your tailpipe during emissions test, you could install the dumb filter the day of test and then remove it immediately.
Much a do about nothing. All petrols across the UK & Europe have had GPFs since 2018. No problems with their function and cleaner air. All is fine. DPFs are more troublesome as diesel creates a loss more and larger particulate matter so the system has to run hot to work and short, slow urban driving does not support this.
I have not heard anything negative so far about them, hopefully they have learned their lessons from DPFs and by not using diesel there are less particles to filter anyway. DPF's problems began to surface about 4 years after they were first introduced.
@@torquecars Well I am having a nightmare with my 19 plate Ford. I do a low milege, but am following all the guidelines in the manual have read them many times over and this warning light comes all almost every trip now, more often once the warranty had expired. The light goes out well before the end of my journey, absolute pile of crap. I paid a lot of money for the car, which is very low mileage, for peice of mind, but it is a constant worry the car will go in to limp mode
My 1.6 TDI Škoda Karoq is designed with the DPF extremely close to the engine which means it gets up to operational temperatures a lot quicker making it a lot more reliable than older designs, personally I’ve not had any issues with DPF’s, those that do are using them to drive 5 minutes into town every day.
More emissions regs to strangle the engine and more to go wrong

lol I have a diesel and have BOTH an cat and a DPF.
Had to replace the cat recently
@@newtonmetereu196 "shouldn´t" :)) very comforting... especially when the new cars cost 30k+ now.
Very informative thank you
Will there be any chance of a "Sports or Free Flow" PPF being developed ?

I don't think the problem you have is with the GPF.

You are talking about a dpf/gpf delete, it can be done. But depending on where the filter is located, it might require alot of work to get to it.
Yay more government in our daily lives
Much a do about nothing. All petrols across the UK & Europe have had GPFs since 2018. No problems with their function and cleaner air. All is fine.
DPFs are more troublesome as diesel creates a loss more and larger particulate matter so the system has to run hot to work and short, slow urban driving does not support this.
so diesel dpf,s are a bad design then ,on purpose or not ........especially considering the costs involved
I have not heard anything negative so far about them, hopefully they have learned their lessons from DPFs and by not using diesel there are less particles to filter anyway. DPF's problems began to surface about 4 years after they were first introduced.

Abolish the EPA. Don't know the EU version, but they should probably be abolished too, lol.
Thank God America hasnt adopted this... yet
