[Filters & Oil] Particle Filter Clogged

[Marak]

Hi all. I have a Berlingo 625 Enterprise HDi 1.6l van 2015 model. I've had a notification pop up about the particle filter clogging, this is the second time this has happened and on both occasions I have taken it into my local garage and they have topped up the DPF fluid at a cost of around £200. The last time this was done was September/October of last year and since it's been done the notification has continued to pop up, I asked at the garage why and they said the fluids definitely been done and it must be a problem with the sensor. Yesterday the van went into 'Limp Home' mode and a visit to a different garage has told me that the particle filter is clogged and it's going to cost me £350 to get it cleaned.

My question is how could the particle filter have gotten clogged if I've had the fluid topped up and is it the fault of the garage that did the work? Any advice would be gratefully received. Many thanks

The garage didn't address the right error. DPFs still clog whether the eolys system is topped up or not (all it does is inject a tiny amount into the fuel upon a refil)

Thank you. Can I ask what should they have done, and do I have a case for them to clear the particle filter for free or give me a refund please?

Likely plug it in and force a regeneration, alternatively a decent sustained A road drive to get it really warm.

What mileage was your van at each time the fluid was topped up?

What mileage was your van at each time the fluid was topped up?

Hi. I can't be sure but I would say around 85k the first time in 2019 and 120k the this time. I bought it in 2018 and it had done 66k.

I can't be sure about the Berlingo as I've never checked, but I've read elsewhere that 35k is normal for some vehicles. Maybe someone else on here has some direct experience of how long the EOLYS should last.

For some reading on the subject, search 'berlingo B9 eolys interval'

At 100k it will assume the DPF ash levels are so high that no more regens can be done and a message saying filter clogging is imminent will appear every time you start the engine.

The DPF must be cleaned out every 100k miles and software called Diagbox used to tell the ECU that the particle filter (DPF) has been replaced.

After that, it will be fine.

Just cleaning it out, or topping up the eolys, or not doing anything, will result in this error for ever. Diagbox must be used to tell the ECU via the replacement parts menu, that's it's been replaced. As well as cleaning it of course.

Yep, it'll need to be reset with Diagbox after cleaning. I was thinking about the double cost of EOLYS within a fairly short time.

On the B9 with the fluid pouch, a full pouch should last 100k miles from scratch. The ECU can't measure the quantity remaining so it calculates it based on mileage and fillups
