I am sure this was discussed in the old forum, but friend of mine lately had a DPF fail on his focus..

Just wondering if the 2.2 Accord has one? and when does it get changed??

Only the Euro V compliant cars have one i.e. the 8th gen Accord and all the Honda's fitted with the IDTEC engine. Nothing to worry about for you.

My Dad had a whole host of issues with the DPF on his Zafira. Ended up chucking the keys back at the dealer after 7 months. They're just bad news.

I have seen people just throwing out the DPF filter and running it without the filter, that just releases all the cancer causing soot straight into the atmosphere.:lol:

As opposed to having the car randomly die every 50 miles, I'd probably do the same if I was unlucky enough to be stuck with a car that had a DPF.

To be honest guys i don't no much about the DPF.I presume its quite a new thing out and it may take a couple of years to get rid of the gremlins.Does anyone no if the 8th gen has any reported problems with this yet.

thing is though they are now saying that the smoke particles, due to the filters, are getting smaller and are more harmful because they can get in easier

I saw my Dad's when it was actually working on his Zafira. It would 'purge' every 800 miles or so. 15mins of thick black smog belting out of the back of the car, then back to normal. Hardly healthy.

there a nessisary evil if you want a new diesel car after this year due to them pesky people in the EU! the next big thing is introducing urine YES ****! to the mixture as it apparently reduces certain exhaust gases. hondas idea was to make the i-ctdi engine as clean as possible so to do without a dpf. many inferior french engines have had to rely on dpf's to gain even euro 4 emissions. they create more problems than they are worth and i have allready had to forcibly regenerate a handfull of i-dtec's.

What?  so you get a tube poking up from under the seat for you to pop the ol' chap into on the motorway to provide your organic DPF with some gogo juice?

From I can tell the DPF does nothing to reduce emissions - it just dumps it onto the motorway instead of the city.  I wonder where there is more wildlife?  Motorway verge or Euston Road?  Phecking eco-warriors.

I couldn't quite understand the logic behind the DFP either. Sure, your emissions will look great, but then when your DFP hits it's regeneration cycle all the soot and ***** it's been saving up gets billowed out anyway.

Looks like a lot of soot coming out when it does it's regeneration cycle.

I hope it's just one of those things that is new and still isn't mastered yet, cos a lot of people I know who've gone for DPF-equipped diesels have had very expensive problems. I wouldn't touch one, personally.

Whilst driving along today fairly slowly as I was on narrow lanes, the DPF warning came on. I had been driving much of the morning at 50-60mph but after a stop of 2 hours had driven about 3 miles in lanes at 20--30mph. I have never had this happen before. I consulted the handbook and made sure that I drove for about 25mins at over 40mph and thrashed it quite well in most gears. However, warning has not gone. Drove later on for 15mins again at high revs. Warning still there. Will this need attention from the dealer (Holdcroft Honda)? Car is just over 2 years old and has done 24k miles. Any help would be appreciated.

Welcome James.

CJ is right, it might need to be hooked up to the HDS system to be forced to regenerate manually. This was demonstrated to us at the Holdcroft Honda meet in Stoke last week for those paying attention..

do the Hondas like Fords that have DPF have a fuel additive tank that needs topping up?

Didn't read the whole thing but looks like a very technical explanation. From what I've read on the internet nearly every manufacturer is having problems with their DPF's (well, when I say manufacturers I mean the poor consumer who has to pay for a replacement. What I don't get AFAIK the dpf is there to catch all the horrible particulates from the Diesel engine to stop them getting into the atmosphere, when in reality it just stores them up then burns them all off in one big go. Seems loopy to me.

Just sell up and buy a petrol.
