Hi all,

As ***le, in the course of all the DPF issues had on here has anyone written to Honda UK with regards to a replacement DPF? Mine has started playing up (re-gened twice in 3 months). So am now looking at the options for it's replacement / removal.

I know most will say remove and remap - no brainer - and to be fair this is the route I will most likely take but there are few companies in my area offering this service. Before I commit to this, I see in other threads that others on here have had a good will offer extended from HUK.

Car has 64000 (2009) miles on it and was a company car serviced within the Honda dealership until it was sold to me 7mths ago by the first garage that it was obviously shunted out to when it was upgraded after 3 years. i have had it looked at at the Honda dealership since so although it is technically outside the Warranty period, it is a main dealer serviced car. Hence I am wondering if there would be a goog chance of getting an offer of a cheap replacement!?!

If I end up going for a DPF removal, there is one local company offering to do the job for £450 inc VAT, inclusive of an additional performance remap. My only concern is that this company wants to cut the DPF open to remove the guts and then weld it back together, which does the job but I am not keen on the removal being visible form the outside (I know the heat shield covers the DPF but all the same...

I would welcome any advice (Fahad) on what to ask for when dealing with this local guy - is there a better type of software that should be used? Can an EGR delete be applied at the same time? Should I insist they knock it out and not cut it open? So many questions.......

Any advice welcome as usual
 
As its got full Honda Service so in theory it should of had the correct oil used. I would start with Honda and see what they say. Point out that its only ever been to Honda so the the DPF shouldnt be failing. Are you journeys long enough to get the DPF to do a regen anyway?

The DPF MUST have 0w30 low SAPS oil from what I can make out. Anything else just seems to mess it up.

As for the cutting of the DPF. If its cut on the welding joins and re welded in the original positions you shouldnt be able to tell that its been took apart I guess. Personally I wouldnt worry. If someones going to that much effort to check, they are most likely to remove the DPF and take a look inside.
 
Staddly my advice is get in contact with Honda UK and explain this to them and wait for there response.If they offer you good will then go for it
 
Yeh, that's what I figured first off. I do mixed journeys so plenty of opportunities to regenerate. Last month the light came on the day before I was due to go on hols do local dealer fitted me in at short notice to gave it done. Travelled to London and back at a decent speed and lo and behold 2 weeks after its on again!! Which leads me to believe it's completely blocked, and was probably well on its way to being so as I bought it.
 
Remove it your life will be better and angels will sing your name , we have endless problems with the things at work . We keep a stock of 6 spare ones and do replace and regen, although recently we have been doing our own regeneration using the steam cleaner due to so many clogging at the same time, needs must and all that . The problem is at idle , it seems like it's 1 minute of idle takes an hour of flat out throttle to regenerate .
 
Try the goodwill route with Honda. I've read they will contribute a fair bit if it has full Honda service history. Make sure the right oil is used after.
 
so turning the ignition off at traffic lights would be a good thing to do then?


We have issued a service warning that all machines fitted with a DPF have not to be sat running at idle for longer than a min or 2 . We can monitor them remote from the office and the dashscreen puts up a No Idle Warning graphic after 30 seconds of idle . So we are doing what we can to prevent idle time , whether it would be worth it in a car ... Maaybe , certainly for longer periods in bad traffic I would shut down .

I've actually been turning the ignition off any way as I was jealous of the cars with stop start technology :rolleyes: I found it increased mpg by 2-3 mpg so is definitely worth doing. Maybe thats why I've never had any DPF problems and do under 11k a year?
 
I thought I was safe(er) buying an ex company car that had spent it's life going up and down the motorway. Can't believe it's all down to the 7 months I've owned it.

Message sent to H UK today so will see what comes of it. The more I think about it though, even if they let me have one for £250 + vat I'll be in for fitting so that's going to be £150 ish + vat so all in that's the cost of a removal with remap!
 
Little update. VERY swift response from H UK. Apparently the will be contacting my local dealer direct to discuss the matter as apparently there is CPU update!

Whether they are actually working towards a proper solution or whether they are masking it with software should be interesting!
 
I had the same issue, 2 forced regens in 1 year, last regen was in August and they also said there was a software update to apply. 3 months later and I have the DPF light on again, car currently with Honda. I'm expecting a new DPF needed. I was planning on selling the car in Jan and now wish I'd just done it straight away. Honda did say the car needed the windscreen trim recal done so that's something....
 
You should never need a new DPF unless it's actually damaged , we have some that have been recycled 10 times now . I don't know how much they charge for a DPF remove and clean but for the spanner handy DIY folks on here we use ... http://www.ceramex.com/about-us/ The Ceramex division in there is a DPF cleaning specialist and I would suspect that it would be done cheaper there direct than going through honda once warrantys etc are expired . They probably already clean honda DPF as they do all the manufacturers we buy from .
 
Honda said a new DPF is needed at a cost of £1100 fitted. They were fine to regen it which I've asked them to do. When I get it back this week I'm going to part exchange it for a runabout until I decide what to get next. Suffice to say it will not be a diesel.

Well we get DPF filters that are for 20 liter engines regened for much less than that . Horrible big things that take much more oven than a car one , they had to buy a bigger oven once we started sending outs to them :lol:
 
I think you will be lucky to get any form of contribution from Honda towards a DPF. All manufacturers suffer from DPF issues and not one is going to set the president by offering a replacement or a contribution because it will open the floodgates.
 
Sorry for late reply on this.

As Neil has said, you can't really hold Honda responsible for this scenario - the problem is really with the fundamental design of the DPF itself, it's just a poor design.

As for DPF removal, it's difficult for me to recommend someone to you - if i'm too far to travel to, just try and find someone reputable. I don't want to scaremonger, but I am correcting work ruined by local tuners on more and more of a regular basis (I had two just this weekend), and this was on older cars with simpler ECU's..

Your ECU will require removal and soldering, and I've seen tuners screw up the maps to the point where it's disabled the cruise control and gearshift economy indicators on the IDTEC's.
 
By the way I regenned two IDTEC's over the weekend also - the winter months seem to cause more DPF problems, especially for taxi drivers it seems..

If you can find a decent garage to do your exhaust work, i can probably do your ECU locally for an agreeable rate.
 
Taxis tend to idle in busy traffic and to keep warm in the winter ,this will quickly munterate a DPF . A DPF must have heat and lots of it .
 
Cheers Fahad. Fully understand what you say about other people's work. I don't hold Honda responsible, just seeing where that line of enquiry might lead.

I must admit I am struggling to hand it over to someone to sort. I am just nervous about the amount of cutting etc proposed.

Is the exhaust work actually that difficult? I am more than a competent diy'er. Would the car run if the work was done and then driven to a meet?
 
Crespo. I've heard of a few so giving it a shot, you never know, worth an email I thought. Not hanging my hat on it though.
 
You'd be best phoning they gave me a DPF for £250 my car was ex lease and had done just over 70k done 30k as taxi since new DPF they also have a new ECU update which is suppose to be a lot better dont know of 1 car with issues with new update, probably put the kiss of death on mine now
 
That's comforting.

Still can't get my head around how a software update could stop it clogging. Answer is it probably doesn't!
 
I'd imagine the update re-jigs the sensors so that the regen process kicks in earlier to help prevent the clogging of the dpf.

Thats exactly what it does ive noticed my cost per mile goes up every so often have put this to a regen taking place but only guessing
 
Yes - it lowers the thresholds for the regen, so it's regenerating more often.

It's not a fix to my mind, and the more and more DPF's i've been involved with this year, i've seen extreme examples of engine failure due to DPF. Most recently a VW Sharran (Taxi) which went through 2 turbo's and finally an engine (build up of sludge around the cam chain and cylinder 1) which knackered the bottom end.

Before tuning, the car will require a regen to ensure the ECU is not in a locked state so removing the exhaust and then driving to me is not really an option.

If you can coordinate with me, I may be able to get to you - best drop me an email to discuss mate.

It gives a post combustion fuel injection to increase the temp of the exhaust gases to activate re-gen . Todays traffic really does not suit the system working well and tall geared cars will struggle more as even on the motorway the engine won't be working hard enough to clear itself .
 
just for you Staddly - I took some extra pics so you can see what's involved. You're welcome to let a local exhaust place use the pics for reference if it helps.

Have a look through our albums, there are many more Accord IDTEC's we've worked on.
 
Bet you couldnt do that in Germany for example, I reckon their MoT and taxi test would check for the dpf working. DPF is there to confirm to euro emissions regs.

Good work however.
