Hi,

Today while driving locally at 30mph i had a warning symbol come up on my car's dashboard. I did not know what it was until i checked in the handbook, apparently it is the DPF (check system). My car is a 2009 diesel saloon executive honda, it has done 90,000 miles, serviced annually at honda dealership.

Does anyone know anywhere local where i can get the particle filter unblocked from as in the book it indicates that my particular filter is blocked, the filter needs repairing or replacing. Now i know the cost to replace the filter is high, would this be necessary? I am based in slough and i was wondering if there was any where close by that i could go to get this particular filter cleaned/unblocked, rather then going to the dealership who will charge a arm & leg for this.

Any help would be really appreciated.


thanks
Mohsin
 
We do both regeneration and removals. Have a look at our website and Facebook page.

I'm in the M4 corridor most weeks but am out of the country until 17th Jan if you can wait.
 
Hi Fahad,

Thank you for your reply, what is your website address?

Thanks

Click on the link in my signature mate.
 
Hi Fahad,

How much will it cost to regen my dpf filter and when can you do it? Ideally i needed this done as soon as possible? Also do you know of any other company that does this?

Thanks

Mohsin are you 100% it needs a regen or just needs to be booted down the motorway to clear the DPF.
Normally the car will give you a warning light to do this before it gets to this state for a regen
 
Hi Brett,

The symbol that has come up is the dpf filter with the exclamation mark, when i read on the book it says the dpf filter is blocked. The funny thing is the dpf filter symbol which comes on with no exclamation mark did not appear, as this is the symbol that the handbook indicates requires long drive at 70mph. This warning symbol never appeared first, only the other one did.

Can you recommend what i should do? Go to dealer? Does the dpf filter require forced regen or shall i just drive the car on a long journey today.



Thanks

I'm not an expert on this but if the car has not gone into Limp mode it might be worth going on a long drive to see if it clears.
Someone hear will confirm this.
Also have you got any warranty on the car if so they should do a regen for free
 
Sounds like you just need to get a forced regeneration done at a Honda dealer, they plug the car in and send the command to force regenerate the DPF which should clear the blockage. They can also check your car has the latest software updates on, as the DPF software has been changed a few times to help stop this problem, updates are free also. Ring several dealers for the best deal, in your area you have about 5 dealers within 20 miles.

I've read they charge anything up to £120 for a forced regen, so not too bad.

Longer term, if you only do urban driving, then a modern diesel with a DPF isn't for you, you need a petrol car. DPF will keep blocking up with soot.

Also only use good brand diesel, ultimate and vpower etc, check your car has the right Honda approved 0w/30 low saps oil, as anything else can cause DPF problems. DPFs are however a service item, so they do wear out after 90-100k miles, so it might need changing.

Hope it gets sorted with minimum wallet surgery…

Hi Rich,

Thank you for the advice, so should i just take the car to the main honda dealer in slough? Or shall i just go on a long drive? How often do i need to drive the car on long journey to keep the dpf block free? The symbol came on yesterday evening and since then i have not driven.

Brett- the car has not gone in limp mode and no longer in warranty although i have a 4 year tailored service plan with the car. I have 3 years left on that.


thanks
Mohsin
 
Sorry I don't know all the answers, thats for you to work out. This is why I have a petrol, none of these problems.

But I'd ring a few Honda dealers and ask what they charge for a forced regen, prices vary, lots around you.

Might be worth taking it on the motorway, keep it in 5th or 4th to keep the revs up, it might, clear, 70mph at least.
 
Have a good read through the threads on dpf's to understand how they work.

No software update in the world will cure this problem, as it relates more to the driving profile of the car than any particular component failure. The very basic design of DPF technology is flawed and relies on a certain regular pattern of long distance driving to ensure it remains within threshold levels for constant regeneration.

You should never see the DPF light. If the light is on it's because the system has been unable to complete a successful regen under normal driving conditions.

You could try a good long blast down the motorway in 4th gear at around 2200rpm for 10 miles. It may temporarily unlock it but in my experience once you see this symbol it will keep happening.

We charge £60 for a forced regen and full diagnostic with engine health check and drop me a line to enquire on pricing for a complete removal with Stage 1 or 2 Remap including DPF and EGR OFF.

We would need the car in Bradford for the DPF removal.

Plenty of examples of our work and what's involved on our website and Facebook page.

Hope that helps.
 
Hi Fahad,

Thank you for your reply, does a forced regen fix this issue and i have been told you should not need to chnage the dpf filter as the filter can be unblocked.

Thanks
Mohsin
 
Nope it just regens it but there are no guarantees. Honda will give you no guarantees with a forced regen either and you will be charged every time you need one.

Your options are to either regen, replace or remove.

All a forced regen does is try and bring it back down to acceptable soot levels within threshold but it's still a used cartridge which will have carbonised deposits that cannot be shifted.
 
Hi

My dpf light came on recently so i put dpf flush, redex and thrashed the car down the motorway for 4 hours but it is still in limp mode.

I am resigned to getting rid of the dpf but want to find someone near to Nottingham Derby or Leicester to do the removal and ECU remap. Can anyone suggest anywhere please?

The alternative is to split the dpf, take the innards out then re-weld it, has anyone done this succesfully before?

I am desperate to get this fixed Asap
 
If you simply remove the internals without correctly clearing the ecu ash counter first and remapping the ecu, your car will be stuck in an endless loop and you have a major problem on your hands.

There are no shortcuts here, do the job properly.

Drop me a line for details if you are interested in us doing the work.
 
Hi

There is an alternative to removing the DPF filter. I have just had my 2010 Accord 90k go into limp mode with DPF with ! indicating that the filter is full. I didn't get the first warning. Before I bought he car I knew it had to have a forced regen, and for over a year it was great, but I was doing 100 miles a day high speed commute, now I am retired I am doing local short journeys, so I was half expecting this. My local garage tried to force the regen and this didn't work. Then then removed the filter and sent it to a company called DPF Clean Team, they clean and test the filter, removed 75 grams particulate, reduced the back pressure from 0,089 to 0.016 millibars. The filter is set to my local garage and the ECU is reset. Much cheaper than a new filter. I know lot of companies off removal but if this is spotted at the MOT it is now a fail, plus the problems with using revised ECU software etc etc. Also by removing it this filter it invalidates its type approval which makes it illegal to drive, although I doubt that you would ever be caught, but it could invalidate your insurance. My garage charged me £354 inc VAT. Still expensive but not as bad as I thought it could be. The filter has a 6 months warranty, beyond that they offer a reduced charge if it needs doing again. Only picked the car up today, so early days, but it the car does another 90k before it needs cleaning again I'll be happy. If I get any more problems I'll report back to the forum.
 
Unfortunately this is only another temporary solution and once you've seen the inside of a DPF you will know why nobody can actually accurately tell you what the actual ash and soot content of your DPF cartridge is.

The ecu is simply estimating according to temperature and pressure differential readings.

Regarding MOT, I'm yet to hear of a failure.

I hope it lasts for you, but it's not a permanent solution and another way of delaying the inevitable. Plus you are still sending soot back up to the turbo which is going to lead to build up inside the vanes.
 
Yes everyone is aware of what the changes in the mot test are.

In practise however nothing has really changed and unless a total muppet has butchered the DPF making it obvious it's been removed, the car will pass. It's been covered to death mate you're posting old content really.

You can clean the DPF as much as you like, it will still keep happening eventually. As with everything in life, it's about your own choice and perspective. If you're happy with this as a solution, then great. Otherwise there's another option too.

Good luck
 
Hi Fahad

Is this DPF issue a dead cert for all us 7th Gen diesel drivers? I do a fair bit of mixed distance driving...daily short school runs etc/medium runs twice a week to my sons football training of say 30 miles each way/long distance once a week or so to his games (Leicester to Bradford this weekend)....reading about this issue gets me concerned that I could also fall victim. Not really what you want to read when youve just bought into Honda diesel's expecting supreme reliability :)

7th gen diesels don't have DPFs... woo hoo!
 
Yup no DPF and nothing to worry in this regard.

The only real issue these have with local driving is blocked egr valves but we have a solution.
 
New member and have been reading lots on here in past couple of weeks, useful forum.

DorsetMark who was the guy in the Poole that did the clean up?

How is it 3 months down the line, still going well?

Just had the dreaded light and exclamation mark come on a week into my ownership! (120k miles)
No previous issues known, the vendor was the company I work for and it has not been a problem previously, I spoke to the owner. I wasn't too worried about the DPF as the car has been doing 80 miles a day on the A31 M27 and A27 for the last 3 years.

Low mpg was the only sign I could think was an early warning. Car was only doing 40mpg.

If end up going the gutting and remap route does anyone have any recommendations down here in South?
Bradford is a long way away F6HAD! otherwise I'd be straight round.

Update. The DPF clean did NOT work. If failed again 1000 miles later, went back for a heavy duty clean and that lasted 2000 miles. What was really annoying is that at no stage did the initial warning show. These are supposed to do an initial warning to say the car needs a Regen, by driving it at speed for a while. All my fails came up with the "!". My advice is if you are happy about the MOT, insurance and environmental issues remove the DPF. If not bite the bullet, DPFs are now available for £400 plus VAT, grant know how good they are. A proper Honda fitted one will cost you £1170, I know I've just paid it, I just want the car running reliably. My Accord had a software update in Jun 13, but the dealers did another two updates again today, when I complained about the lack of initial warning lights. So worth getting the updates checked by the dealer. It looks like these only have a life of about 90,000 miles, so as long as mine new DPF lasts another 90,000 miles I'll be reasonably happy.
 
If you want it to be reliable, take it out. I'm afraid that really is the only sure fire way to ensure it.

You're not the first I've seen who has replaced with a brand new genuine dpf. It will just happen again but I hope for your wallets sake it doesn't.

Update 18 months later (fingers crossed) and the very expensive replacement DPF is still working. I am still concerned that everyone who has had this problem says that their car went directly to full failure mode and didnt get the interim warning, as described by the owners manual. Honda dealership said that their update has solved that problem, I hope that is right, I remain unconvinced, although it is clear that they have been trying to solve the problem with software updates, mine seems to have had lots! There has been a lot of interest recently in dirty diesels and the amount of NO2 particles they produce, the DPF system was designed to reduce the problem. It appears that VW may have opted for a diferent solution! I am pleased that I put a proper replacment in, without a DPF there are risks; insurance invalidation, MOT failures if the DPF is missing and spotted and finally increased pollution. Might be worth checking with the dealership every service to see if there are more DPF software updates?
 
18 months is not unheard of and I wish you luck with it.

No software updates work, it's a filter and by virtue of its design it's life is a limited one.
 
OK so I have had 3 forced re-gens over the last year. My car has done 195k so I figured I had probably had my monies worth and I have just had the filter and pressure switch replaced. 500 miles later the DPF with ! comes on again. Whenever it has block I only got the symbol with the ! never the warning. Now the garage says it is a faulty ECU or injectors. Does anyone have an opinion?
