Exhaust Particulate Filtration system reset as used on Citroen/Peugeot HDi diesel systems.
Particulate filtration is used to remove the un-burnt particulates from a diesel engine’s exhaust gas to lower the emissions. Without a further ECU controlled process this filter would become blocked and need regular replacement.
An additional ECU controlled function is used which injects an additive into the fuel tank, this additive modifies the particulates in the diesel fuel and makes them burn at a lower temperature, The ECU will also promote burning within the filter by using post injection (injection of fuel via main injectors when the exhaust valve is open). This post injection process will promote burning to continue down the exhaust pipe and therefore burn off any particulates that have been held in the filter.
A system re-set is required when the additive tank level drops below a pre-determined minimum. This should occur at about 50,000 miles.
The additive should be purchased from the manufacturer’s main agent and used to top up the additive tank (found in the main fuel tank) once the top up has been done the system can be re-set via the serial diagnostic socket using the SP MAP system.

So it would seem your car has some kind of fancy exhaust gas recirculation system, and it requires an additive to keep things clean. I'd find a good indie in your area and get them to refill the additive, and reset the ECU (if what I've posted above is correct, that is).
/edit: just seen your reply, and that quote is extortionate. I suggest you join a good Citroen forum and take advice, I'd be astounded if you couldn't do it yourself for less than £50!

Hello
I have just purchased a Citroen C5. 10 days later i got the message displayed "Diesel Additive Minimum Level" I have look in the owners handbook that says urgent top by your Citroen dealer (what it doesn't say is it will cost you silly money).
As anybody found a way round this, IE how do i fill it up? I understand you can buy the fluid but you may need the car pluging into a service computer to turn the warning off?
HELP

I didn't find a way round the issue. I used and independent (garage where I bought the C5) who put the addative in, and took the car to the local Citroen dealer to reset the computer. As the warning appeared soon after purchase the garage paid half the cost.

So, if you don't fill this up.....
What?
Will the car cease to operate, or is it just a chemical which re-heats soot in the exhaust system, removing the particulates to make less smoke? If so, are you remotely bothered?
Now let's see. £230 to prevent a tail-gater getting a face-full of soot when I floor it. Difficult call.
I was told there would be no issue with not filling it up. However, it may impact the emissions and therefore could be a MOT failure so ..... worth the risk ???

Are the particulates worse than an ordinary diesel wothout this technology? If not it's probably worth seeing if it passed the MOT first.

I just got my car through the MOT, emissions were fine and the warning message has been coming up for 6 months now.
Only Citroen dealers can do the job, they won't release the ability to indys to do it, too much money in it for them to do the job (unless anyone else knows different) I know my local Nationwide Autocentre tried to get it done and Citroen would not play ball with them.
The local dealer is quoting anything up to £400. They can't even be certain what the problem is as there is a sensor not working right at the filler tube which could be causing the problem.
Why I bought yet another Citroen is beyond me

What a delight to read that I'm not the only one puzzling over this! Our C5 is currently displaying 'Unblock Diesel Filter' and 'Diesel Additive Minimum Level' - even though the fuel filter has just been changed! On calling our Citreon dealer to get a quote for the Diesel Additive, we were told that we must have our particulate filter changed and the additive topped up - "It's not cheap Madam - about £1000 plus VAT"!!!!!! Still trying to get hold of additive - is it worth it? -we've been advised that these warnings are purely computer generated and not part of the engine management system.
ocks to emissions.This is the additive for the diesel particulate filter. As far as I know it has to be topped up by the dealer and is part of the normal service schedule - not sure if any independents can do the work. Thankfully, this sort of particulate filter is on its way out: they are now moving to coated ones that don't need any additive.
Helsbells - it sounds like your one might have been poisoned somehow - high sulphur fuel can do that. If your C5 is one of the recent 2.0L 136ps versions, it might well be capable of meeting emissions limits without a DPF at all.

BE AWARE, MESSAGES LIKE DIESEL ADDITIVE TO LOW, OR ANTIPOLUTTION FAULTY, NEEDS YOUR ATTENTION, THE PARTICULATE FILTER WILL CORRODE AND CAUSE RUNNING PROBLEMS, IE ENGINE MANAGEMENT LIGHTS ON THE LOT, YOU CAN DRIVE THE CAR FOR UPTO 10 MONTHS WITHOUT THE ADDITIVE, BUT THEN YOU WILL CAUSE THE DAMADGE, THERE IS A LOT OF PEUGEOT SPECIALISTS DOING THIS REFILL AT A FRACTION OF THE DAFT DEALER MONEY, AND SOME DEALERS SAY WHAT WHEN YOU TELL THEM OF THE PROBLEM, IT IS EASY TO DO BUT NOT DIY, IF YOU ENGINE MANAGEMENT LIGHT COMES ON IT WILL NOT BE ON AFTER YOUVE HAD IT DONE.
