DIY DPF Clean At Home Citroen Picasso

We remove the DPF (Diesel Particulate Filter) from this Citroen Grand Picasso C4 and do a manual clean. had an Anti Pollution Faulty indicator up and the car threw up other fault codes as well. We used the GAT Off Car DPF Cleaner 1 liter. We was amazed at the results.

Did the fault codes go off instantly after re-fitting or did it go off overtime and it with diagnostics.

I just did that to my completely clogged 2012 1.6 Grand Picasso dpf, and it is running beautifully since. Mine had neither the heatshield, nor the tabs that kept it in place - after unscrewing just the two collars and the pressure sensor line, it practically fell off by itself. Thank you for this great and very informative video, you gave a complete amateur the motivation to tackle this, with excellent results.

Great video guys glad you got her fixed good to see pals helping each other 👍

[@retrorestore]

[@tomkusmierz]

Chaps, DPF's filter soot - but over long period it clogs up with ASH. Ash comes from 1. poor quality diesel (high sulphur content etc) 2. wrong oil. SEA rating (such as 0w30) is not the thing to look for. If your car has a DPF fitted, you should look for ACEA C3 / ACEA C2 engine oil. Those will warant very low ash content and extend intervals between required DPF flushing. Good luck !

[@honestguy7764]

Low saps engine oil is paramount to avoir clogging

[@garyhardman8369]

In 2007 I bought an ex- demonstrator Mazda 6 Diesel. I did not know about their DPF system. Basically, when it senses exhaust back pressure due to a semi-clogged DPF, it injects extra fuel on the exhaust stroke, in order to try to burn the carbon in the DPF. Unfortunately, some of the diesel fuel by-passes the piston rings and ends-up in the sump, diluting the oil. When the sump level reaches a high enough level , the engine achieves what is called a 'diesel runaway - where the engine revs uncontrollably , bein fed with an un-metered mixture of fuel and oil. This happened to me and it was a frightening experience! When I searched the internet, I found hundreds of people that this had happened to. The general opinion was, that the noxious oil/fuel exhaust gases would have damaged the catalytic convertor, requiring a replacement, which at the time was about £2000. Much correspondence with Mazda revealed that they did not care less about the situation. So, in two years of ownership, I traded the car in for less than half of its market value. I would NEVER buy a modern diesel again, and would NEVER set foot inside another Mazda dealership.

[@retrorestore]

Wow, that's not good. I agree modern diesels emission control is no good for cars that do short journeys. Very poor design

[@sdgelectronics]

Most DPF systems don't operate this way. They either have a separate fuel injector just before the DPF or they use Adblue or similar. The exhaust stroke injection method was only on a small handful of vehicles.

[@mickbobin]

So many automotive 'fix it' videos I need to turn off as either there is no explanation throughout the video or the camera work has been abysmal. This video was like a breath of fresh air and with a bit of humour thrown in... Well done :)

[@kevinbrowning7352]

That’s the same engine we had in our Ford Focus I’ve had 3 EGR valve s fitted and my local ford garage Mechnic said I wouldn’t even bother replacing it they go wrong for a past time it doesn’t sound like that’s your problem however if you have it blanked off and mapped out it will improve the performance and help to stop it blocking up Hopefully plus it will improve the performance and help the engine breath better

I learnt a lot from this video although have a completely different car. Those regen's just don't work. If soot clogs these decrepit things up, you just got to take it out the way you guys did and clean it properly.

[@thestorytelleruk]

I'm just about to have a crack at my C3 Picasso. Cheers fellas. One thing I would suggest to anyone trying this: you want to make sure it's bone dry before running it as water and soot don't mix very well. You don't want gunk setting hard in there so soon after you've cleaned it!
