307 FAP filter

External Since: Sep 25, 2007 Posts: 23

I'm getting the "Unblock Diesel Filter" message on my 307. I have had the
FAP liquid (can't remember what it is actually called) topped up as it was
low and could have been a symptom of the message (apparently). I'm begining
to think that the filter does actually have to be changed. I spoke to one
Peugeot garage and was told (after giving them my VIN) that it was a first
generation filter and should be changed after 48K. When I bought the car it
had 42K on it and the garage told me they were going to give it the main 48K
service prior to collection. I feel that if the garage agreed to do a 48K
service, even though the milage was only 42K then they should have changed
the filter at the same time. The car has now done 53K and the error message
keeps popping up every now and then. I haven't contacted the Peugeot garage
I purchased the car fom yet - still feeling the water.

Are you brave enough to take the filter off the car yourself? It is the one
in the centre of the exhaust with the heat shield under it. It has 2 pipes
going into it, one at each end, and a temperature sensor halfway down.
I took mine off and reverse flushed it with several kettle-fulls of boiling
water, interspaced with blowing out with compressed air. I did this until no
more white residue (the ash which clogs the filter) came out, then dried it
out for a bit and put it back on the car.
Apart from a bit of steam out the back when I first started it up, all was
well, and the message has not returned. It has now done about 7k miles since
then.
PSA do do an exchange unit for this at somewhere near £200, but many garages
try to get you to buy a new filter at nearer £500.
All PSA do is wash it out and send it back.
