Isuzu DPF issues again

[ricky_rascal]

My Ranger 3.2 auto has been faultless since it arrived 2-1/2 years ago, including a thrash to Shropshire last weekend for myself and drillman junior to visit a certain seller of puppies. Speedo was reading 3 figures at one point on the M6 toll with plenty to spare.

It‘s a good bit of road that toll road for warming a DPF up Hope certain seller of puppies and family were ok. Really pleased with pup. That was about as far as the d-max has been in over 12 months to pick the pup up. Otherwise all local apart from going to skipton with livestock trailer.

To be fair d-max has been faultless until last week when it started regenerating rather too frequently. Will see how it goes. Should not be blocking with low mileage it has done.

Possibly a stuck egr...

Hmmm, possible! Would a dose of oven cleaner and propcorn help

Definately worth a go

Lots of threads on piston heads about blocked dpfs seem they drill two 14mm holes with a 400mm masonry drill bit which is enough to reduce the back pressure without putting the light on

That’ll need access to the DPF from the top which is not visible to the MOT examiner, might involve removing complete exhaust system to do it on some models - If you go that far why not split the top remove the offending item, weld back up again and get it re-mapped. Job done.

If you remove guts out of said filter then you need to bottle brush the exhaust outlet as soot would give the game away I’m sure it‘s not uncommon removing DPF filter but it is illegal and will void your insurance - subject to getting caught.

Had a 90 mile round trip last night and it seems to be regenerating at about every 30 miles. Seems quite common on Isuzu Facebook group. Engine runs fine and doing approx 30mpg without trailering so think egr is working. I’ll keep an eye on oil level and see how it goes.

What would dpf filter have to do with insurance?????

Possibly because it’s classed as an mot failure even if the mot tester didn’t spot the modifications. If an insurance firm wanted to wriggle out of paying that’s 1 way they could do it

I’m no legal expert but evidently that because you have removed or tampered with the filter it would fail an mot. Now plainly a lot are going through mot without issue. The fact that it is illegal and ‘should’ fail an mot then the vehicle isnt roadworthy and therefor insurance is void. This of course if you are found out. If I’m wrong then please do chime in but is what I believe the situation is. Gov are trying to clamp down on pollution from particulate soot from diesel in the air so a dim view of it is taken.

Ours does a lot of short runs but try and take it on a weekly blast or it goes on the stock box.
I've never been so let down by this truck. It runs like a bag of sh!t.
Do all yours have this horrible hesitate when you accelerate? it starts to go then dies for a second or 2 then it will go. Might do a double hesitate now and then. So dangerous when overtaking.
Dealer and Isuzu don't want to know.
Was in there 2 weeks and pulled out dealership and did it within a mile.
I just think they know there rubbish and we're stuck with it.
I've heard the autos are better than the manuals and this is just a utility truck so quite basic.
Can't wait to get rid.

Had 2 ranger 3.2s . Both have needed glow plugs to aid starting by 13000miles with the most recent also needing a turbo at same time . I also do very short trips and it's clear these modern diesels don't like it . My latest one also has adblue and it's a hesitating heap about the doors but put a trailer on and it's smooth and great to drive .

Disappointing for you. Mine has throttle lag which is only noticeable when setting off. You press the pedal and nothing really happens for something around a second. Doesn’t sound a lot but if you need to pull out of a junction in hurry you need to account for the delay. Fly by wire throttle I’m told is problem but notice the Hilux I drive now and again, doesn’t do it or the Ranger I tried. It’s auto by the way. Other than that it doesn’t hesitate once rolling. But yes they know of the problems such as the DPF and do their best to ignore them. That said the dealer I use at York do their best to help but expect hands are tied to an extent by Isuzu.

So basically Rangers are unreliable Now I’ve said that Drillman will be down off the hill above and beat me to a jelly I nearly traded for a Ranger just over a year ago and some fellas in shoot said I’d dodged a bullet? Should I fall out with the d-max, then what? Would a S/H Ranger or Amarok be jumping out the frying pan into the fire. Bear in mind I’d still do a good proportion of shorter runs?

Might take a bit of convincing on that one if you’ve had it from new

current ranger approaching 3 year old and been as good as gold. Having driven a few D max and towed with them a bit I wouldn’t have one. Ranger knocks them into next week in all areas imo.

Going back three and a half years I did look at a Ranger as I’ve said before, up at Richardson’s at Driffield. Back then it was common for a 9 month wait. Did the deal in the end on another 2.5 d-max but there was the nagging doubt in the back of my mind. But it seemed it was the early ones that had issues with diesel in sump and low miles between regens. Seems not to be the case and the 1.9 would appear to be no better. Current d-max has been faultless but with about 30 miles between regens now and at same time engine tone has become very noticeable when it is regenerating the DPF, my confidence is starting to look misplaced I keep hoping that in a Time Lord (Dr Who) style it regenerates into an Amorak or Ranger

I notice on an Isuzu Facebook group that the main topic of conversation seems to be ’how many miles does your d-max do between DPF regenerations?’ to which every other reply seems to include who will remove the DPF altogether and remap the ecu. Other popular query is wheel spacers

Iv raised a query with isuzu about my post. I had a long chat with Lee that deletes dpf and egr. I’m a bit concerned about doing this because of mot and insurance invalidate but it’s fairly unlikely they would take it apart to check.
It’s quite concerning how isuzu seen to have no clue how to fix or prevent the problem.
I’m hoping however isuzu will redeem their reputation though and start talking about the problem.

Regen every 30-40 Miles?
That cannot be right
My Hilux hardly does a regen, that I noticed

Never ever noticed my Ranger do a regen in almost 3 years of ownership

 

[2wheels]

i have just traded in my golf sv 2.0lt diesel. it has never done a regen in 85500mls. it was swapped for the same again with the dsg box this time. went for a run up deeside today and the bloody emmissions light came on. going in on monday, probably just needing a reset.

 

[H200GT]

Hardly ever notice my Navara regen, only time I can tell its done / in the middle of one is when I happen to park up mid regen. There is a faint hot smell outside the vehicle and sometimes a faint tinging sound as the exhaust temps are up. Other than that I’d never know it was doing it.
