I know this subject has been covered at length before but I can never seem to get the forum search to work, so I'll be brief.
My friend has a 2004 607 as above, which he hasn't owned for long and the particulate filter is coming up to requiring its second servicing procedure at 160,000 miles. According to the service record it was serviced at 80,000 miles.
The 'filter clogged' warning light comes on from time to time and he naturally wants to sort it out.
He lives in France but is frequently in the UK and he has been quoted 600 pounds Sterling by a UK Peugeot dealer to replace the filter and top up the required fluid.
Is it always necessarily to replace the filter and is this price reasonable?

Here it says the filter is cleaned and the fluid topped up:

I can't believe that it wouldn't be way cheaper in France. Some English people take their French cars to Calais for the day to get them serviced, while buying smelly cheese and vino collapso!
The filter can be cleaned and/or is now an exchange item @ £150, I think

Particle filter (PF)
Particles have a diameter of around 0.09 microns and consist mainly of carbon and hydrocarbons. The PF traps these particles and periodically burns them off.
Particles burn naturally at approximately 550 °C, but the normal temperature of exhaust gases leaving the manifold is only 150 °C.
The particle filter system overcomes this problem in a number of ways :
*
post-injection during the expansion phase, resulting in post-combustion in the cylinder and a 200 to 250 °C increase in exhaust gas temperature (i.e. to between 350 and 400 °C) ;
*
additional post-combustion by means of an oxidising catalyst located upstream of the filter. The catalyst acts on any unburned hydrocarbons resulting from the post-injection and raises the temperature by a further 100 °C (to between 450 and 500 °C) ;
*
use of Eolys, a cerine-based additive that reduces the particle combustion temperature to 450 °C.
The particle filter system consists of the following :
*
a housing containing the pre-catalyst and filter. The filter is a porous block of silicon carbide that traps all particles in the exhaust gases. Sensors monitor clogging pressure across the filter and the gas temperatures at the inlet and outlet of
*
the system ;
*
a software programme in the engine control unit that controls regeneration of the filter by post-injection every 400 to 500 km depending on the clogging pressure across the filter. The software also provides diagnostic information on the system. During regeneration, the inlet air is no longer cooled by passing through the air-air intercooler but is instead heated to raise the temperature of the mixture in the combustion chamber with a consequent increase in the temperature of the exhaust gases ;
*
a fuel additive system consisting of a probe tube, a system to inject Eolys into the main fuel tank and a dedicated electronic controller. The Eolys is stored in a tank adjacent to the main fuel tank and injected in proportion to the volume of fuel added during refuelling. For example, when filling up with 60 litres of fuel, the system will inject 37.5 ml of solution containing 1.9 g of cerine. The Eolys tank has a capacity of 5 litres, sufficient for 80,000 km.
The filter is cleaned and the Eolys tank refilled during dealer servicing every 80,000 km.

Hello Mike - long time no see! Hope you are well.
These particle filters on certain Peugeot models are a right pain in the behind if you ask me! The amount of anti-pollution faults these cars used to flag up was unbelieveable, only curable by a visit to Peugeot and the parting of a minimum of £500! No after-market diagnostic kit (at the time) is available to instigate the routine, leaving you with no option to go to a dealer or trade in your car to a dealer who you hoped wouldn't notice the fault!

See the threads on the C5, which has a similar filter. probably identical.
I am on my second C5.
Your friend's Pug probably has the newer extended life filter which is a normal service item every 80k miles or so.
FAP+Eolys filter top up costs (Citroen C5 2.2hdi)
Quoted GBP350 in UK (Tyneside) in Feb.
Paid EUR 450 in Germany this week.
In my experience the ECU starts throwing up warning messages about 2000-3000 miles before replacement is due.
I had quite a variety of messages.
Diesel filter blocked was the first one.
Anti-pollution fault was the second.
Then the Service + engine warning light stayed illuminated all the time.
Now completely cleared.
I have noticed that the MPG improves just before the Eolys fluid "runs out".
It should be easy to change the language on his display and check the exact French/German fault message.
A diagnostic download ( fault codes) at a Cit garage varies in price.
GBP40 up north at aforementioned garage.
GBP70 at a midlands dealer.
Pug dealers in the uk tend to be more expensive than Cit.
Probably due to Pug market position and higher number of company cars.
(I also drive a friend's 307...)

You too mate! Wanna change a Prelude exhaust system for me?
Do all the newcomers on here know who they are reading? ;-)
