Peugeot 307 SW - Unblocked Fuel Filter - paulket

I have a fault coming up on a Peugeot 307 HDi which states unblock fuel filter, When it comes on it puts the Engine Managment light on, the performance doesn't seem to alter and when you restart the engine the light goes out.

The fuel filter itself looks fairly new as if the previous owner may of had this problem before selling it!!

Any clues would be gratefully recieved.

I think it will actually say " unblock diesel filter ", this is the Diesel Particle Filter ( DPF ) fitted to the exhaust system to reduce pollution. If you do lots of short journeys the DPF can get clogged up. A longer journey in a high gear above 40mph will clear it.

Search Eolys & DPF on this site & Google for more info.

Yeah that's the message. I've put some DPF cleaner through it and it seems to be making a difference fingers crossed.

It''s also making a bit of a rattle when under load it's fine when on tick over and when you rev it up but when you're driving at about 1500 revs it rattle a little, any clues!!
