Technical DPF's - anyone done 100k on one as yet ?

[nec]

I have an unending curiosity on the subject matter and would be grateful to hear if anyone has done more than a 100k on a dobby with a DPF and of course whether there has been any problem.

Also if anyone drives owt else fitted with dpf what their experience has been overall - there are endless hgv's knocking up 24 x 7 mileage and they all have them fitted (since 2007).

thanks in anticipation..

worked on loads of taxi scudo/doblos with well over 100k on them being used 24/7. If your asking if any of them have had DPF problems at this mileage? no.

Good news - thanks for that

How do you carry out a regeneration manually please ? - if it is a goer I think I can increase mpg significantly...

I have a 2006 Doblo 1.9 JTD with 101,000 miles on the clock. The engine went in to limp mode at 100,000 miles. The local garage & the dealer tried (but failed) to force regenerations and told me to replace the DPF. I did this (£413 for the DPF from online automotive + £115 fitting at local garage) but it didn't solve the problem. The car was back in engine failure/limp mode within 500 miles. The problem must be somewhere else. Don't know where yet, but will update this forum when it is finally fixed.

Thanks for your sharing.Wish you can resolve the problem soon.Good luck.

isnt this the issue - those that are running hot and regular - as with all motors - will be better suited to dpf that namby pamby private owners who do short runs... and run into problems?

My brother has just bought a Skoda Octavia and he tells me that the Skod website is full of questions and concerns over the DPF. They all have their problems, not a lot can be done about it. As for Mrs Bean's Dobby, I suspect it has a DPF being a multijet wheras my Stilo won't as it's just a JTD. The Dobby is possibly going to suffer because she does a lot of urban driving but it does get a decent run regularly so here's hoping.

Could be but I would say alot of taxi runs are shortish distance and with fuel the price it is the engine would be getting turned off alot more in between fares.....any taxi owners confirm this?

I would assume the skoda uses the VW system which is useless, VW garages are simply cutting the DPF's off as they cannot rectify the problems they are having. Going to be fun seeing how the vag group are going to meet euro 5 emissions (which Fiat have already surpassed long ago) :devil:

I am told that the Audi A6 has a new 'mod' to the common rail which does away with the DPF - can't see it somehow - does anyone have an understanding as to what is the next generation of DPF please?

 

[ivantate]

The only mod to the rail can be even higher rail pressures.

I think for the Euro5 emissions if you dont have a DPF you will have to use urea injection. So basically every car will need the DPF.

Not sure how much trouble they really are, also it may stop people hugely overspeccing engines for their cars for the work they are actually doing. The manufacturers like Merc and BMW dont help when the sell a detuned 2.0 diesel engine as a 1.6.

I should imagine very few 06-on Doblo vans with the 1.3mj have any problems as they will be upto temperature and driven at 70%+ for most of the time they are running.

OK, here is how this particular saga ended: After 2 weeks at the dealer the technician diagnosed that:
1. The No.3 injector was overfuelling.
2. Oil deposits were building up in the inlet manifold.
3. The turbo oil seals were worn.
4. The turbo boost sensor was blocked with carbon deposits
....all of which was causing the DPF to fill up and preventing regeneration.
The technician cleaned out the oil & carbon deposits and replaced the boost sensor at a total cost of £520. This solved the problem. The car drives like a rocket and the DPF regenerates no problems. However he warned that the problem would recur unless the Turbo was replaced (£1,000) and possibly the Inlet manifold & timing belt too (£900) + oil & filter change (£100).

Hope other Doblo owners find this information useful. As for me, I have sold this Doblo on cheaply and have bought a 1.4 Petrol Doblo instead. In fact I don't think I'll ever buy a diesel car again. They are far too complicated nowadays. 19th century petrol-technology for me from now on.

Thanks for this and nice to know although I suspect you have been unlucky - it sounds as if you had all the problems - but fingers crossed

£100 for oil change

why not just change the faulty injector?

1. Yes, that's correct. Oil & Filter change quoted at £97.33 inc VAT.
2. Don't know why the injector wasn't replaced. Was the injector at fault....or was it the sending unit/sensor that was faulty and causing the injector to overfuel? I've no idea. Just glad to be rid of it.

 

[ivantate]

maybe the new owner will be on the forum in a couple of weeks to sort out the same problems.
Sounds like getting the injectors serviced would have stopped most of the problems.

 

[T14086]

did anyone carry out a spill test

I woiuld get new recon injector, dont have faith in serviced ones.

Don't know if a "spill test" (whatever that is) was done. No mention of this in the paperwork or during conversations with the dealer.

The new owner had a fleet of Doblo taxis, so knew what he was doing.
