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.

You have discovered something very rare. Even when Attenborough goes to inhospital places on earth to sneak a glance at creatures never before seen by man cannot compare to the rarity of what you have just uncovered.

You found a reason to buy a 1.3litre diesel Astra.

The OPs question was ` Can anyone tell me of any other diesel of around that age and size which does not have a dpf`

And the Astra is certainly no worse than a 1.6d Focus

it's better than you might think to be honest, or at least there's plenty worse out there!

0-60 in 14 seconds and a theoretical 72 to the gallon. cheap tax too.

Yes and taking frustration to new heights of the absurd, unless the revs are in torque band...ie over 2k rpm...then rice pudding skin will stay firmly attached, about as nice to drive as a Corsa with the 3 cyl petrol...which would struggle to power SWMBO's sewing machine.

Even the 1.7 isn't wonderful till you get it up to revs, the 1.9 fitment turns it into a decent car.

Yeah you would think so but the wife had a 90bhp one on a 58 plate and it was a canny little engine. Believe it or not this had the same motor :- http://www.conceptcarz.com/vehicle/z6147/Opel-Eco-Speedster-Concept.aspx

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..

http://uk.cars.yahoo.com/car-reviews/car-and-driving/vauxhall-astra-1.3-cdti-1004766.html

And from World Car Fans:-

Developed by Fiat-GM Powertrain, the 1248 cm3 four-valve power unit with a compression ratio of 18:1 features cutting-edge diesel technology. Its high-pressure common-rail injection system (1600 bar) provides up to five injections per cycle, for ultra-fine fuel atomization - a key factor for smooth running and performance. A highly stable grey cast iron casing (bore x stroke: 69.6 x 82 mm) further contributes to the engine's exceptionally smooth running characteristics. The bed-plate and cylinder head are machined in lightweight aluminum. Contrary to the 51 kW/70 hp 1.3 CDTI unit with 170 Nm, which is offered in the Corsa, Tigra, Combo and Agila models, the new engine´s turbocharger features variable geometry, enabling maximum torque of 200 Nm at 1750 to 2500 rpm. Peak power of 66 kW/90 hp is delivered at 4000 rpm. The very compact 1.3 CDTI (length/width/height: 460/500/650 mm) is the smallest common-rail turbo-diesel engine in the world.

With specific power and torque values of 72.1 hp and 160.26 Nm per liter displacement respectively, the 90 hp 1.3 CDTI is one of the top four-cylinder diesel engines in the industry. It takes the five-door Astra 1.3 CDTI to a top speed of 172 km/h, and accelerates from zero to 100 km/h in 13.7 seconds

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 !

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?

Diesel without dpf - dieseldogg

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?

I have the 1.3 cdti in the Corsa 90hp version and to the best of my knowledge it has a DPF, not sure whether the Astra id different. Certainly in my handbook it indicates that I have the DPF. I will concede it is not the best engine I have ever driven but its certainly not the worst!.Derv Dave - I posted a thread on here recently about my engine - basically it has a slight lumpiness whilst accelarating gently through 34, and 5th gear, normally between about 1750-2000 rpm. If i accelarate hard its not there. Did your Astra have this?

Diesel without dpf - capricorn

I've just bought a Peugeot Partner 1.6hdi with dpf (reluctantly) and as I do nearly all urban driving need to give it a blast up the motorway now and then apparently according to the dealer.

Naturally, the dealer is going to put the best spin on what I need to do so does anyone have a view or better still experience of the 1.6hdi engines with dpf, please?

Incidentally my last car was an 08 Renault Grand Modus 1.5dci without dpf and it returned

on urban driving 55 plus mpg.

It's true I'm pretty frugal as a driver but that's still good i think and the car never missed a beat.

I had the 1.3ctdi 75bhp in a new (57) Corsa. (No DPF but fitted on next model year) That had severe judderring in a very narrow band around 1300rpm, made tootling around a car park a nightmare. Also very prone to stalling when pulling away at roundabouts and in a very violent way. It would start off, hesitate, judder and, IMO, the ECU would decide its had enough, cut out and the engine stopped stone dead either on compression or backfire i.e. bang and violent stop. It eventually caused a severe accident, as a guy behind me ran straight into the back on me causing over £2k damage. Luckily no whiplash - my young grandson was in a well designed baby seat.

Occasionally it appeared to backfire while starting an again in my opinion ran backwards for a couple of revs - extremely painful noises - god knows what was happenning.

Dealer were useless and would never find a problem - not surprising as their technicians drive everywhere at full revs.

It did have a software update which cured another problem - the tendency to accellerate sharply by itself when braking e.g. approaching a red light and the engine revs dropping below about 1500 revs it would suddenly pick up by itself and surge forward for about 1-2 seconds - very disconcerting....

IMO the injector system and software were not fit for purpose. The multiple injection design maybe on the limit of what is physically possible.

Also it sounded like a very clattery sewing machine, bounced around on the road unpleasantly usually not in a straight line, never returned much above 50mpg and had a crap heater. I will not buy a small diesel again.

I lost my faith in GM completely with that car, but more recently I've hired a basic 1.4 petrol Astra (not the latest shape) twice whilst abroad and on both occasions been pleasantly surprised about how nice it is to drive - plain and simple - sure the internal styling is kitch but very reassuring drive and surprising economy - almost 50mpg. However, as a negative, the air filter box had to be removed to change a headlight bulb and the engine bay looked a nightmare for DIY servicing.

Think twice about buying a small diesel....

You can buy a brand new Hyundia i20 1.4 CDRi Blue Drive, NO DPF. mpg 76.4 combined, CO2 98g, it's packed with equipment.

The engine has lots of torque but it does drone a fair bit.

Diesel without DPF - focussed

Brum is absolutely spot-on with his comments about the nasty little 1.3 Vauxhall diesel which is actually designed by Fiat (Fix It Again Trevor). I had one in a Corsa and the description of the stall if the revs get too low and the ECU just switches the engine off is that it sounds like the world's strongest man has hit the bottom of the car with a sledge hammer. Pedestrians stop in their tracks and turn around and laugh, dogs start barking and old ladies drop their shopping.

Avoid.
