Dpf replacement

[twosmoke300]

I would agree with a corsa d being shit . One of the worst Vauxhalls ever made ( sintra not included )

[sierraman]

I don't know, probably a bit unfair, a lot get neglected by people who haven't a clue about cars. Fairly dreary to drive, the engines sap the life out of you.

 

The Insignia is ok, the one my old man had was chronically unreliable though I he might just have got a bad un.

 

Vauxhalls are one of those you either love them or you haven't time for them.

[Liggle]

but Vauxhalls just didnt wear well, Insignias and Corsas on 10,000 miles but felt like theyd done 40,000 miles, im entitled to my opinion and that is that Vauxhalls dont wear well whatsoever, not modern ones anyway.

 

I'm not a Vauxhall fan after years of company cars I didn't want and couldn't opt out of but I have to disagree. It depends how they have been treated, like any car, I put 55k miles on a 2011 Corsa 1.3 CDTI and it was faultless. It was also gutless, thirstier than my Octavia vRS TDI and uncomfortable though   

 

I also had an Astra 'Sports Tourer' after the Corsa which at 65k miles started throwing up the DPF warning light, which in process takes out the speedo and rev counter to encourage you to stop!

Bren's 'terrible' Vectra is probably only 20-25 miles from me, and I get the work's bonus next month

 

 

Ps: if anyone has a Corsa D that they think is shit and wants to sell me cheap, get in touch. I bloody love them, we've had two in the family and they're great. Have to say the 1.4 is actually like a sports car compared to the 1.2 though!

Must agree on the 1.2/1.4 comparison, the 1.4 is a stonker of an engine in a corsa but the 1.2 is horrific.

 

I used to always get those bloody 1.2's as hire cars through my old work and they were worse on fuel than a 2.0 Mazda!!!

Also going back to the dpf issue my guess is that although it's not going to be dead easy, the sensors in these will be able to be bypassed with relative ease. The merc ones use effectively a differential pressure gauge to measure in and out and provide the ECU with an appropriate resistance/voltage/current measurement while others use a flap to do the same thing.

Getting the correct resistance readings from a good one and then transposing these into the ECU should provide the same effect.

 

Yes it sounds easy* but obviously will require a bit of electrickery but shouldn't be impossible to fix.

[Bren]

I will attempt to clean the car's egr over the weekend and have a look at the pipework etc.

 

I have said to my wife(its her car) that I will look at a terraclean but nothing more than that - after this you are replacing expensive parts.

 

All this has made me realise what a damn good car our mk1 focus tdci was....

A lot of ECUs get upset if the pressure differential doesn't change. If the sensor flags up that a regen hasn't happened after so long, it triggers a EML. You really don't want it doing a regen without the DPF element in place.

[twosmoke300]

Agreed - the ecu looks for a certain amount of differential pressure and will throw a light/ limp home if it stays static over a certain amount of drive cycles.

[sierraman]

I'm not convinced the 1.0 Corsa was actually capable of independent movement. Painfully slow. Didn't like the 1.8 VVT either, made an awful noise, no go at all.

 

The 1.9 CDTi was ok but like any diesel, could be trouble, it's a throw away job once it goes on the slide.

[Pillock]

Remove dpf and slice open lengthways. Remove guts.

weld back up

Reinstall.

Remap

Problem solved FOREVER

Problem solved until they work out how to tell if a car that was sold with a DPF, still has a DPF during an MOT.

 

At that point I think you'll start to see a lot of otherwise fine cars being scrapped as not only will they need a DPF, they'll need the ECU reflashing to remove the bypass. Double trouble.

[Hendry]

Could you summarise that for me because it's a bit long! Is it that you don't think vauxhall's are as good quality and they give more trouble at high miles? If so not sure I agree. All much of a muchness in my opinion. Don't a lot of makes share components nowadays?

 

Im not talking about the mechanical aspects at all here, i dont think, and i dont think they give more trouble at high miles, because the Vectra my old man had was bought at 7 months old 12000 miles, it was ran into the ground for 7 years and traded in on 232,000 miles, yes it did go through a lot of tyres, brake pads, discs, coil springs, bushes, ball joints, bearings, droplinks, banana arms, and seemed to have an strange appetite for brake calipers, however other than the clutch and flywheel failing at 140,000 miles which is fair enough, the only major failure was the steering rack, first one lasted 2 years/70,000 miles, its replacement lasted less than a month, the replacement after than lasted around 9 months, and then finally the next one lasted for at least the next 4 years until the car was traded in, no idea why, faulty parts, badly fitted, recon parts, no idea, but they were all genuine Vauxhall parts and the work done by a Vauxhall franchised dealership, so yes mechanically id say Vauxhalls arent overly troublesome at high mileage mechanically. My point is solely that they really feel their miles, they dont hide the mileage well, they even when in A1 mechanical condition really look and feel the mileage theyve done, my car is rough cosmetically, its worn inside, but when youre looking at the road as you drive along, it honestly feels no different to driving a low mileage Golf mk6, with a Vauxhall its much easier to tell which one of 2 cars is the low miles and which is the high miles one, like I said 2008-on Renault Meganes and Clios are like this, as are Peugeot 207/208/308, maybe its the rattles, the poor interior build quality, the cheap seats, interior trim and panels which wear quickly.

 

Surely what im saying here isnt alien to people, sit in and drive a modern Mercedes and youd be hard pushed to guess itd done 200k, same with a Mondeo, a Passat, but get in an Insignia and right away its obvious its leggy without even seeing the odometer.

 

PS My 2015 Corsa was the Corsa E, a heavily facelifted version of the D, well specced car and in my opinion looked smart, but it was crap, just as crap as the D, only saving grace was id driven a 1.2 D before so ordered the 1.4 E for not totally glacial movement, if I hadnt driven the D i wouldve bought a 1.2 and messed up even more. My big regret (other than buying the bloody thing) was not getting the 1.4 Turbo with 6 speed box, it really needed a 6speed box for lower RPM at 70mph, and the 1.4 T despite on paper only having 10bhp more, was the same cost to tax, not much more expensive, plenty low down grunt, loads of torque, and much more driveable, very turbo diesel like to drive, which suits me because although im not arsed about diesel or the faults, issues, whole pollution shite with them, I do like the way a diesel drives, plenty of low down pull, can wring its next upto speed and then settle there, im not fussed about a high performance car which can do crazy top speeds or has loads of HP or can easily get to over a ton on the motorway, nah i just like to make brisk progress infront of all the dawdlers inner city, urban areas, and motorway slip roads, once im upto 60/70 and nobody gets in my way and causes me to slow down im happy to just cruise along at that speed, so something that drives like a turbo diesel but without the associated issues would be ideal.  Corsa D 1.0s were that bad that new car transporter drivers struggled to get them up the incline onto the transporter at obviously low speed, apparently something that has also now affected the Fiat 500 now theyve tweaked it for eco bollocks. 

[bub2006]

That every high mileage vauxhall is a worn out bag of shit and the mondeo was like new with 150k - yeh right

Off topic slightly but my dad's mondeo didn't feel as tight at 135k when the gearbox blew as my wife's vectra did at 161k when the cim died so I have to agree there!

I was told that the DPF deletion detection in the MOT is likely to be applied only to 2006/2007 onwards cars. I don't remember where I heard it. I think that the smoke test limits changed about that time.

 

With the 2001 607 that I had the MOT station told me that they had no way of knowing whether it was supposed to have a DPF or not.

[SiC]

I think it's more likely to be 2009 on, as by then it was mandatory to have a DPF. My 2007 Civic doesn't have and never had a DPF, despite a lot of other competing cars having them.

I was about to say they probably wont care about a 2001 car because it wasn't mandatory until much later, so a car with no DPF is going to be so common they wont even check if they see one without it, because itll mean a total ballache finding out the build spec of the car to see if it had one fitted etc. Im sure the French manufacturers called the DPF a FAP when they first used them (whatever that means, I just know I searched it one and it related to DPFs) and from what ive seen when I see diesel engine French cars of that period advertised, their full Sunday names usually say FAP or non-FAP at the end, even on an otherwise identical car, for example a 2005 Renault Megane 1.9 DCi Dynamique 130bhp, one would have it and the other wouldn't, so Mr MOT Man is going to know that and just say awk this one was probably built without one because it was that hit and miss with what ones did and didn't have them.

Yeah that's what id have thought too. What I do wonder is if it would be an MOT fail to remove the DPF from a car fitted with one which was built before they became mandatory and as such could at the time have legitimately have been built without one.

 

Picture the scenario, I take my 2009 Jetta in for an MOT having visibly removed the DPF, im obviously going to fail because not only is the car registered as having one and all technical data says it should have one, but because its a blanket rule on all diesels registered after a certain date theyre going to know straight away it should have one. Now imagine someone else takes an identical Jetta but 2006 registered in for an MOT, DPF visibly removed, are they just going to think "ah well it doesn't have one obviously if its not fitted because they weren't mandatory at that point" or will they actually get all anal and go checking if the car should have one and fail it for not having it, even though it legally didn't need to be fitted with one, is it a case of if it was fitted you cant remove it?

 

Kinda similar to the question about Cats on pre-1991 cars, not mandatory, but if fitted when new, it must still be present and cant be removed, but if it was never fitted to start with then that's ok. Bit of a grey area this one.

 

I frigging hate DPFs, pain in the arse which wouldn't be required on diesel vehicles had it not been for the government 25years ago trying to get us all into diesels saying they were less harmful than petrol cars, and basically incentivising diesels, then they get most of the country into diesel cars and then do a U-turn, and because of their incompetency we are saddled with these stupid hopeless systems which have fucked up so many decent diesel cars which other than the DPF issues would probably be quite reliable cars, and have cost us fortunes to repair.

[5speedracer]

Aye, take all the advances in diesel engine tech and throw away the emissions gubbins. Now you're talking!

[Captain Furious]

I know its all relative to value of car/personal wealth/appetite for changing parts etc, but aren't DPF's a bit like cats were 25 years ago - in the respect that the scaremongering stories about them costing 10 zillion pounds to replace put everyone off buying a new car with one fitted

Granted £318 is still a fair whack but its not something I'd scrap the car for (assuming the rest of it was decent) I've had far more eye-watering bills on my pez Mondeo.

 

I have actually dealt with that company before and they were spot on, but no liability accepted if the parts turn out to be chinesium tosh..
