DPF clean

[Bertie]

Hi all,
Thanks for all your advice on a previous post.
Cars recent issues...blowing exhaust smoke in to cabin, also produced engine management light. Split EGR pipe replaced and issue solved.
2 weeks later, bloody DPF light came on, and limp mode.
Took it back to Honda specialist and forced regen performed, but warning light cane on after a few days again.
Now booked in for DPF removal and clean.
My questions to you all are;
1. Has anyone had a successful DPF clean that's lasted more than a year or two?
2. I can't removed the DPf etc, so would either have to try and sell the car with a fault or replace the DPF. If I chose to replace the DPF, should the EGR valve be replaced at the same type, and/or other parts that are likely equally filled with sooty crap?
Thank
Chris

How many miles are you doing a week and are any of them long runs ?

What was the last MOT emission test result and is it much different from previous years ?

Hi,
It gets a good run most days, about 40 mins each way, and most of that at 70 or 80mph, so about 3-4k revs.
Don't know the last MOT emissions, but there were no advisories.

If you want to keep the dpf present then you must replace with a brand new genuine Honda dealer item, new differential pressure sensor and vacuum pipes as a minimum. I would also recommend replacing the exhaust gas temp sensor at the same time, as both sensors are used to measure and activate the regeneration cycle.

It’s not necessary to replace the egr valve.

Thanks, that's a really helpful answer. I shall hold out for a lottery win tonight, as I guess it could be 2 or 3k all in!

Sell the car to someone who is willing to have the dpf removed and buy yourself a petrol or electric car.

 

[Bertie]

Yep, it's certainly a sensible option, though I'd essentially have to give it away. Either way, I'm stuffed as I just spent £3k on buying it...only had it a couple of months

Why so anti dpf removal?

 

[Bertie]

Not anti as such, but my employer would be if I was unlucky enough to get caught out at MOT!
