Hi looking for some advice on dpf clean, this is a Peugeot partner 2018 that I just purchased, a warning light has came up for dpf and needs cleaned, looking to do it myself with a can of dpf cleaner, all I need is someone to confirm the location?

Can't seem to find a way of uploading a picture of location.

Where I think it is is directly underneath facing from side loading door on passenger side, there are 2 thin pipes leading to a nut that to my understanding needs unscrewed and to insert the tube to clean with the cleaner, is this correct?

Any help appreciated, thanks in advance.

Not the questions you asked, but...


Why does it need cleaning? Is if life expired, or is there a fault that's caused it to become blocked - has it been fixed?

I suppose it's normal for it to get clogged up with soot, much the same as the egr valve.
A warning light has come up to say that the dpf valve is needing cleaned..
There is a slight loss of power because of it it seems.

Do I thought I would try this myself before taking to the garage.

Are you certain the warning lamp relates to a valve? It might be saying the DPF fuel vapour valve is blocked, in which case you'd need to remove and clean or replace it. But it may be telling you that the car needs a DPF regen, which you'd usually do by taking the car on a long run.

Sometimes DPFs get so bad that they need cleaning. You can buy fuel additives which are intended to help clean DPFs and I wonder whether this may be what you have bought. If so, it should have come with instructions.

In extreme cases you can take the DPF off the vehicle and literally wash it out, and there are companies that will do this for you if you don't want to DIY.

That fault isn't saying the DPF is blocked!!

Its saying there's a problem with the emissions and/or running (probably running rich as DPFs dont like that) and there's a RISK that you will kill the dpf if you don't get it fixed.

You need to find out whats causing the problem first. Not start fannying around with dpf cleaners that wont fix it

So I took it to a garage, they forced a regen and it worked...for about 1mile, lights came back on and went into limp mode, now talking about cleaning the dpf with a can of dpf cleaner and take it from there, if anyone has any other suggestions...thanks

Was still considering cleaning it myself but need to know where it's located to spray the cleaning solution.

There are two ‘life’s’ to a DPF, there is the soot load, once this reaches a threshold, the engine should trigger a regeneration event to burn off the soot and reset the system.

Then there is the ash load, when the system is regenerated the soot is burned and becomes ash, the ash doesn’t go anywhere, it stays in the filter. Once that level is reached a new DPF is the only answer.

How many miles has it done?

That isn't how DPF cleaning works.

It's said that there is a location on the cat/dpf that you spray the cleaner into, a foam spray and leave to soak then take it for a run the next day,

Just needed to have the location CV informed where to spray it into, all I know is that there is a sensor to be disconnected and a nut yo be unscrewed to put the tube into and clean it that way.

I'm skeptical about those foaming cleaners. IMO there's very little chance they will achieve anything. If the DPF is blocked with soot, it can be cleaned using a regen. If it's blocked by ash, it can be cleaned by taking it off the vehicle and reverse washing/flushing it.

If you're determined to try it, you need to locate the DPF on the vehicle and locate a sensor upstream of it. There will typically be at least a pressure sensor takeoff somewhere upstream.

I thought you concluded that the error message you're getting indicates there's a problem on the vehicle which might lead to the DPF becoming clogged, not that it was already clogged. DPFs are designed to be self-cleaning (until they're blocked by ash) and if they do become clogged it's typically the result of some other fault. If it isn't actually clogged your time would be better spent addressing whatever that error message is warning you about.

Check the level of the Eloys system, needs to be on diagnostics. It uses eloys to lower the temp that they regen at and they normally run out around 100k.

Risk of dpf blocking is the result of something else, checking the dpf soot and ash content can be done with diagnostics, you should never force a regen unless no other choice.

Clearly the OP knows better than either of us, and is prepared to waste time and money on the symptom and not the cause.

WTF do people post time and time again for advice, then ignore it! laugh

Going to take some of your advice and pass it onto the garage,

I've decided not to go with cleaning the dpf as it's not directly indicating that's it's the dpf but it's saying "risk of particle filter blockage.
Just trying to diagnose the issue without having to take to the garage,
The first garage I took it to forced a regen and now I'm slightly worried that that was a mistake going by what Stevemcs says, then the garage says he can spray it with dpf foam cleaner which you are saying is a waste of time/money and what I was going to do in the first place.
Taking to another garage who will have a look, so I'll give an update later.

Thanks all for advice so far
