Diesel without dpf - Alan

I shall soon be looking at auction for a replacement car of about three years old. I don't specifically want to buy a diesel but most of the ex fleet cars at auction are diesels so I limit my choice if I avoid them. If I buy a deisel I wish to aviod the hassel of a dpf. I shall be looking for a focus or astra size car. I am told that the 110bhp focus has a dpf but not the 90bhp but I don't know up to what date that changed. Can anyone tell me of any other diesel of around that age and size which does not have a dpf or one where if you have problems with it you can comfortably throw the dpf away and still pass an MOT.

Of the age you are looking at (over 18 months anyway), Kia Ceed 1.6 Diesel.....and as a bonus no DMF either i believe.

I don't think the Toyota Avensis has a DPF

Why? I bought an Octavia 1.6 TDi with a DPF.

12 months and 19,000 miles later, I have not been aware of its existence.

I should add that for a week at a time the car does 3 miles to work & is parked.

does 3 miles home for lunch & 3 miles back.

is parked

drives 3 miles home.

Is parked.

With obviously longer faster runs between times.

I suspect the key is to find an engine installation that was DPF designed from Scratch.

That is what I figgered with the VW 1.6, as opposed to the interim 2.0 diesels with a "bodged" midlife DPF installation

ditto for Renaults new chain cam "quick heating" 1.6 diesel with DPF

Interesting observation. With any luck DPF problems will perhaps go away with newer engine designs arriving all the time....

And at that point, no doubt, EU regulation will ensure another bit of bodged on hardware to deal with some other emissions! ;)

As the DPF is suposed to help the environment, has anyone worked the net cost of all the poor fuel consumption, down time, expensive replacements, using more natural resources etc?

The EU is just a pain in the DPF!

I have a new shape A4 2.0 TDI 143, and it had given no DPF issues at all yet. I was talking candidly to the dealer and they saiud that the new gen of DPF 2.0 diesels had virtuially none of the issues of the outgoing models.

I do mostly motorway cruising, however one week I didn't go anywhere much and my wife did a number of supermarket/school trips, I noticed that this was enough to make the car go into 'regen' mode.

This cautious configuration could be one of the reasons for the lesser DPF problems. I think on the older cars it took a lot more than this to get them to regen.

Again I suspect the key lies in "the new shape" i.e. a throughly reworked design I would suspect.

When I looked below the bonnet at the 1.6 TDI engine/DPF installation I noted the DPF was located as physically as near as possible to the exhaust manifold, as opposed to being "bunged" in somewhere in the run of exhaust pipework below the floor of the vehicle where there just happened to be room.

PS

I have smelt the DPF ,I can only presume, a very "hot" smell when parking her up after the 3 mile lunchtime run, no light on the dash or any other indications though..

Going back to the Vauxhall subject, is that 1.3 diesel the same as in the Tigra? Tragic.

The little 1.3 vauxhall engine actually performs alright, I recently had an Astra and I was unsure if it was the old Isuzu 1.7 unit or the 1.3 until I looked in the glovebox.

If you want a shocking small engine look at Fords 1.4 TDCI 67bhp with the narrowest power band you will ever have the fortune to drive !

I think all small diesels are pretty shocking, i really dont see the point. 1.8litre is really the smallest i'd consider.

The VAG 1.6s feel quite pokey - even in 105 PS form.

The 1.6hdi used by PAS,Ford and Volvo has plenty of get up and go well more than adequate power and speed.

Going back to Alan's first lines, no more than half of new cars sold are diesels - so there should be plenty of used petrols about, which are normally cheaper than their diesel equivalents. You don't have to buy from auction: have a look at Autotrader if you have a particular model in mind.

If you're happy with a Focus there are lots of petrol ones around. Better to drive than an Astra but there are plenty of those too.

On Auto Trader currently, for cars up to five years old theres around 126,000 petrols and just over 102,000 diesels but its interesting when you zero it in to just hatchbacks, 85k petrols to 37k diesels.

That means around 60% of cars currently for sale are under five years old.

Diesel without dpf - Crinkly Dave

Hi Guys
I am interested in this chain, as I have had a 1.6 105bhp Octavia Diesel for 18 months, and am interested in getting rid of the DPF to see if I can improve driveability, as it tends to have a mind of its own at times. Any links you know for companies doing this?

I have never had the regen light on, but at times the thing seems to be thirsty for a while, which I suspect is extra fuelling to burn off the DPF?

Crinkly,

I was of this opinion at first, but am no longer aware of it, despite my very mixed driving I am getting just over 50mpg-3% for the computer, that is mostly short run urban stuff with a 100 mile motorway 80mph run once a week.

On our recent 4 week Continental run, over 5000 miles, about 900 on autobann at 130/140kmh plus 4100 non motorway miles, plus urban stop start stuff..... we averaged from start to finish, brimmed tank at both ends........60.564 or thereabouts.

I say again....... brimmed figures.

so jist drive her.

I "think" the key with a DPF diesel is getting it hot enough often enough, if this is achievable, no? or very very little excess diesel is needed?
