C30 DPF fitment

[KiethsV50]

Hi All,
Currently dealing with a DPF issue on my C30 1.6D with my local garage. The previous owner had it cleaned in January and the EML light is now back! The pressure coming out of the back is next to nil so they are checking all the sensors for resistances and voltages to ensure I do not clean/replace the DPF only for it to happen again!
My question is, it seems to currently have a D2 DPF fitted, is this ok, seems to be they just added a flexi joint (for a reason)?
cheers
Scott

Having had DPF issues in the past with out V50 1.6D I can only recommend making good by buying the correct DPF from Volvo (was about £250 when we bought ours) and that should see you fit for another 75,000 miles. I've read so many posts about people cleaning them by various methods, removing them or using aftermarket parts. If you rely on your car, in my own opinion, it's simply not worth the hassle to scrimp and bodge.

Just get the OEM part and you shouldn't have to worry for years to come.

I speak from my own experience only. Others will no doubt think differently.

You are 100% correct . far to many un-knowledable people bodging up the cars now and ruining them ...

and "cleaning" NEVER works , its a scam ...

Depends how its cleaned, if you send it off to have a high powder jet of water flush the ash back out the way it came it will work fine. To do it yourself you are going to have to cut it open and weld it back together. The DPF on the 1.6d pug however is serviceable, its a shame volvo doesnt use the same one

If you understand the complex interior maze , there are millions of 90 degree corners which can never be flushed out they have to be burned out in the regeneration process . Anyway by the time you have paid for a "flush" its false economy just get a new one ... Guaranteed to work for 75000 miles or the life of the car if a D2

Ash can not be burnt only the soot can via regens, thats why DPFs have a finite service life because of the accumulation of ash, if it was just soot you would never need a new DPF. Ash has to removed mechanically, If you look at the video you will see the sand coloured ash being removed. Lorry DPFs and some peugeots DPFS cant be disassembled so that you can clean the filter. In our through away society manufacturers have made most DPFs not serviceable to save a few £ on manufacturing.

Id rather not get shafted for £250+ and instead clean it myself. I realise not evenyone has the time and or inclination to do so.

No , the Volvo particle filter/Catalytic converter clean themselves at every regeneration it burns everything out at 600C . , Most of them are lasting the life of the car at the moment except the ones which need the additive and changing every 75000 miles . but these finished 10 years ago . Cleaning is not a service item .. I can see how a lot of people make a lot of money out of it though :-)

Why not?

Because of the way soot and ash lodge in the millions of minute 90 degree corners inside the complex labyrinth of channels , have a read up on the elements construction ...

I know how a particulate filter is made thank you. Water can also travel through these channels just as exhaust gasses can and even better under pressure. Adding a DPF cleaner which is more dense than water can also travel everywhere given the right amount of time. There is no scam it's simple physics.

Oh and there are no 90 degree corners in the filter, if there were the engine would definitely run poor (no matter which engine cause it would start backfiring) and cause a turbo whine which in time can lead to a disaster. Exhaust gasses MUST have free travel otherwise you risk engine damage.
