The fuel additive, whilst promoting regeneration to burn off soot particles, leaves a small ash residue which cannot be burnt off. It is therefore necessary to replace DPFs requiring the fuel additive at the 120,000 km service interval. αν ισχυει την κάτσαμε την βαρκα!
Την κατσαμε την βαρκα. Απο το λινκ που παρεθεσες βρηκα τα εξης σημεια:
Does it require maintenance?
Any filter has a finite capacity, so diesel particulate filters must be cleaned out if they are not to block. This is most important, as an overfilled filter can damage the engine through excessive exhaust back pressure and can itself be damaged or destroyed.
When the DPF is becoming full, with around 80% load, it automatically cleans itself by initiating a process called regeneration. This process increases the temperature in the DPF and burns off the soot particles. To initiate regeneration, the DPF needs to reach and maintain a high exhaust temperature. This is normally achieved during motorway or higher speed driving. This "passive" regeneration occurs continually, and will go unnoticed by the driver.
In certain circumstances (e.g. frequent short journeys or slow driving in congested areas), automatic regeneration may not be triggered. In this case, an amber warning light illuminates, with a message "soot filter full – see manual". The manual explains how regeneration can be initiated. When regeneration is complete, the message is cleared automatically. It is important to take immediate action to regenerate the DPF. If regeneration is not achieved, soot will continue to build up, and the amber warning light will illuminate again, with a different message: "engine service required". The vehicle should then be taken to a dealer immediately for forced regeneration to be carried out. Failure to do so will cause difficulty in starting the engine, and may require complete replacement of the DPF.Because smaller engines run at lower temperatures, a fuel additive may be required to promote regeneration. This additive, Eolys, is currently used on Volvo's 1.6 and some 2.0 diesel engines where a DPF is fitted. The additive is a cerium/iron based solution that is added to a special tank under the fuel tank, which holds approximately 1.8 litres. Additive consumption is low and the tank is topped up as part of the car's regular service schedule.
The fuel additive, whilst promoting regeneration to burn off soot particles, leaves a small ash residue which cannot be burnt off. It is therefore necessary to replace DPFs requiring the fuel additive at the 120,000 km service interval.

Do I need one?
The fitment of a particulate filter to diesel-engined cars is becoming increasingly commonplace in order to meet emissions legislation and to achieve cleaner exhaust gases.
Nevertheless, driving constraints in such locations as inner-city and islands (e.g. Channel Islands, Isle of Man) are unlikely to facilitate passive regeneration. Please consider your driving style and normal driving conditions to determine whether a diesel- or petrol-engined car is best suited to meet your needs. Your Volvo dealer will be pleased to assist you.
Αρα μαλλον ισχυει σε γενικες γραμμες οτι αν η χρηση ειναι κυριως μεσα στην πολη χωρις μεγαλες αποστασεις, υπαρχει παντα ο κινδυνος να μην ανεβασει αρκετη θερμοκρασια η μηχανη ωστε να οδηγησει σε re-generation του DPF φιλτρου....
Σκεφτομαι να εκτυπωσω την σελιδα και να παω στον αντιπροσωπο Volvo που σκεφτομαι να παρω το αυτοκινητο να το συζητησω.....
Οποιδηποτε γνωμη ή εμπειρια απο κατοχο D2 κινητηρα που κυριως κινειται μεσα στην πολη χωρις μεγαλα ταξιδια μεσα στην χρονια ειναι παραπανω απο ευπροσδεκτη
αυτο που λες ειναι εξτρα ρανταρ στον εξτρα εξοπλισμό που δεν θυμάμαι τωρα ποσα παραπάνω κοστίζει!
