Hi all,
My 63 plate C4 Picasso just greeted me with the Particle Filter Additive Level Too Low warning (or words to that effect).
So I've been phoning a few garages to get quotes.
One came back with £173 all in.
Is this reasonable? They said it's about 30 minutes work.

Not heard back from Citroen themselves yet.

Would it be cheaper for me to try and source the pouch myself and get a garage to fit it?

Also - how urgently do I need to get it replaced? Can I go a few more tankfulls?

The issue is that the system needs to be reset usingLexia/Diadbox. The replacement of the pouch is probably easy; its whether they ave the diagnostic softwae to reset the counter.

At a guess I would say the bag of Eolys alone at Citroën will be around £200 plus the cost of a diagnostic (around £70 to £100 these days) and 1 hours labour another £100

I would have thought that an independent garage with a high-end code reader (Snap-On, Autel, etc.) would be able rest the counter.

Or you can reset yourself using Diagbox

Hi the cheapest i can find for mine, it's the older Picasso gp from 2010, is from autodoc, her the bag cost 1300 DKR, or about 120£ ?? I guess.

You can properbly get cheaper if you look around and buy only the eolyse, i bought a 3liter kit for about 170 £.

But yes you need to zero things, i have had some luck with my autocom, that is a nice little kit for the hobby mechanic who might get different makes of cars.
You can also get a fault where the dpf is full of cerine (eolyse) and it can throw both of these codes, it seems a bit confusing and that will not go away by zero out before the dpf is changed,
I believe they can be around the same time as the fluid too?
