Diesel Particulate Filter Problems - Page 2

My Pajero has now done 85,000km since new. Not had one DPF light come on once. 99% of the time this vehicle is used on VERY short trips for school runs. Occasionally it will do 1000km in a week but thats once every 3 months.

I know when its trying to do a burn off, as the fuel consumption will go through the roof for a short period of time... EG. Driving @ 100kph, normal consumption would be 9.5 or thereabouts, when its doing a burn off, its about 12-13 litres per 100km... after 5 minutes, it just settles down and gets on with business.

NS Pajero's were/are notorious for having problems with DPF, so either people have worse driving conditions than what i have used mine, or I have just been lucky. Definitely has one fitted, as it has never blown one puff of black smoke, and the exhaust is pretty much completely clean, when it comes wash time.....

Magic stuff

The Subaru carbon cleaner wasn't designed to solve this problem on DI engines as Subaru have never had a DI engine until the BRZ was released a month or 2 ago.

But it does the same job on a non DI engine as it would on a DI version. Ford have there own version from Motorcraft called Carbon Clean.

80kmh?
Mazda say no more than 40-50kph @ 2000rpm from memory.

Our crap v8 landcruiser at work, (didnt toyota go backwards with that engine), 180000km needs injectors, $10000 to change, they are going to sell it as its an 2007 model, nearly worth half the car or more to fix, rediculious

Injectors for my Focus are $920 each, but I only have 4 of them.

Checked the manual for the Mazda 3 last night; 2000rpm, 40kph, 10-15 minutes to clean. I guess that would be the same for all small diesels out of the PSA alliance.

Thanks to everyone for their posts. I think a lot has to do with where in the exhaust system the DPF is located, the closer to the engine where its hotter, generally the better. My diesel had its DPF about three quarters of the way down its exhaust system. Another thing is that its quite likely manufacturers are now designing DPF's that are more user firendly, (easier to achieve effective regeneration across a broader spectrum of operating conditions), than they used to be.

I am considering buying a Capitva 2.2 4cyl Diesel.......but this makes me have second thoughts on diesel power?

Nic85 · 18-10-2012, 10:50 PM

A Captiva? I strongly suggest you look up all the quality issues with Captiva. Just about every other car in its class is superior in nearly every way.

IceValk85 · 18-10-2012, 11:32 PM

^^ a captiva?

seriously, id rather walk.

and i own a commodore lol. even the red team will disown them.

UtesRGR8 · 18-10-2012, 11:41 PM

Yeah, I've been reading heaps on them and it doesn't look good. The missus likes them but I will have to try to steer her away.

DJR David · 19-10-2012, 07:00 AM

The Captiva is just a jacked up Epica. As the driver of a work provided Epica for the last three years I suggest you purchase a bicycle!

Our work fleet is changing over to diesel Cruzes. Lots of issues with DPFs. People having to sit in their cars for 10 minute parked whilst they clean............ truly hopeless

Has she looked at the new Hyundai santa Fe? I saw one the other day and they look nice. But a lot of people are hesitant on Hyundai.

Got a few in the fleet at work the two 2011's have had gearboxes replaced due to something coming loose in the transfer case and cutting the housing to shreds. Both under 20000k's. One overheated towing the boat and family coming back from Robe. Mine has has the inter cooler hose split last Friday night and not want to start. Bluetooth works on occasion. Torque off the line is good to 80km/h after that it's very average and it goes through diesel. Turbo lag gives me the SH*TS but overall for the money it's ok and comfortable. Holden needs to improve quality control because in the end it's a Korean built car.

The Holden service Manager said city driving kills them so dont drive it slow and keep the rpm's up especially around town. I can say that I have happily obliged and in 25000k's have not had it come on again..

But if you have to run the engine at higher revs to keep the filters from blocking... doesn't that negate the need for a fuel efficient diesel in the first place?

Probably why diesel in falcon is a silly idea.

Bossxr8 · 19-10-2012, 09:05 PM

The 2.7 diesel doesn't have a DPF.

Had a quick look at the Hyundai today..the top of the range model looks alright but I didn't drive it. I also didn't ask the price. They had some ex-Hyundai company Santa Fe's 2012 model but since updated with 12000km -14000km on them. They want between $36,000 and $39,999.

You would have hoped that Holden would have had ample opportunity to catch alot of thes issues as they seem to have been around from the release of the first Captiva. I'm worried that even if you manage to get a trouble free Captiva, the resale value will suffer because of all of the issues. I know a few people who have them and whilst they are happy overall they have all had issues including a fan belt breakage and an oil leak from an unknow location in the engine after only 2 weeks. The broken belt required their new SUV being towed home.

I am trying to convice my missus that a Jeep Cherokee Limited will be big enough for us...and probably a little more capable off road for me and the son to go bush/fish. I don't like my chances..she wants 7 seats.

Nic85 · 19-10-2012, 11:55 PM

Probably better off with a Territory if she wants 7 seats, or even a couple year old Mitsubishi Outlander VRX.

if they are the top of the line Highlander model, thats a cracker deal. considering they are over 52k new.

boss was thinking of one, but the useless mob of apes at the hyundai dealership here dropped the ball by A/ not having one to drive... at all, and B/ not returning his fone calls as hes now lost interest lol.

Exactly right. Friggin green fleet policies aren't worth a pinch of ***** in my book.

Every time it has gone in its the same response. Yes we are aware of it and there is an updated part to fix the problem. Well I am going away around Xmas will it get me back home and how many more updated parts are needed?

What happens to all the **** in the filter when it's burning off... It's being released into the atmosphere, it's only there to pass emissions tests at a certain point in time, a crock of **** that will scare used buyers away in years to come and drop the resale of whatever it's fitted to. Diesels seem to be a bit of a fad for city slickers especially euro buyers. Fortunately the euros are investing in small capacity turbo petrol engines that achieve similar economy.

Rodge · 20-10-2012, 10:00 AM

smoo - The soot trapped in the DPF is burned into ash as part of the regeneration process but the ash slowly builds up over time inside the DPF so the DPF's will need periodic cleaning or replacement.

DPF's are a bullcrap device put in place to meet the B.S. requirements of the Global warming B.S. poltical correct greenies. My diesel vehicle simply didn't work properly with the DPF in place and I would be extremly reluctant to buy another diesel from any manufacturer with a DPF.

Diesel Terry hasn't got one...that would be my choice if I was in the market for that sort of vehicle. No DPF, they handle and go pretty well, lay-down maziare hand if you ask me.

kevino · 20-10-2012, 10:54 AM

My mechanic told me dont buy any Holden finishing in the letter A.

IE
Viva
Vectra
Astra
Barina
Captiva

Why -he gets lots and lots of money off customers to keep fixing them.

I think the model was called the Trail.

Big Damo do you have contact details of who recodes the ecu? My wifes 2009 Focus is showing a code for a blocked DPF, been to 3 different workshops no one can clear it replaced nearly every sensor. So it seems there is a DPF issue. Ford have quoted me $6200 plus fitting. About all the cars worth.

Hello Stephen,

Thats interesting because I've got a 2010 TDCI Focus and it doesn't have a DPF?

My Focus is in at 4B Fabrications and Performance in Carrum Downs at the moment, having more tuning done, they turned off EGR as well for me I believe, it can be done through software so they would be able to disable DPF features and remove it no doubt.

I'll send you a PM with their number.

Odd problem though, wonder why your Focus has a DPF and mine doesnt?

rjk74 · 20-03-2015, 05:48 PM

Do Mitsubishi Tritons have DPFs at all, thinking of getting one as a work car.
