Hello, i understand that the 2.2L diesel C5 has an auxilliary tank linked to
the fuel tank that injects a small amount of mysterious 'additive' into the
diesel tank every time the tank is opened controlled by a little microswitch
under the filler flap. My question is; does the 2L C5 have the same ? My
mate has a Peugeot 307D, which appears to have the same, because a warning
light has come on. Will it cause any permanent damage to the engine if this
is not attended to immediatly, like a month down the line. Cheers. Ray
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 engineís 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 manufacturerís 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.

Yep, that's the thingy. Only the original 2.2HDi C5 used that particulare
particulate control, that I'm aware of. It's hideously expensive fluid -
about £60/litre, IIRC.
Won't do any harm if it's empty, it'll just be a bit sootier than it should
our C8 has the same 2.2HDi engine
yes there is an aux tank and yes you will need to replace the particle
filter at around 50k miles and top up the diesel additive
the 2.0 HDi doesn't have the filter or aux tank
originally we were quoted £560 for the filter PLUS fitting, which, because
they have to drop the engine would have been an extra £400 ish
6 weeks later the same Citroen dealer quoted £539 including the 50k mile
service, labour and parts
the additive is about £12 litre and the filter turned out to be £169 + vat
