Unblock diesel filter 307

Thanks for sending that its the Cat and sensor you need replaceing,
which is part of the exhaust, there are very pricey,best thing to do is
ring round and find some one that sales them ,done one on a vaxhall and
that was a lot of money,has it had to be vauxhall part.it is a job you
can do yourself.
good luck chris..

 

No Chris, it is the particle filter in the exhaust which is blocked.
The prices quoted are normal for this, and to my knowledge, they are
only available from the main dealers. The exchange unit is one which
has been washed out.

Barney, I don't know how handy you are with mechanics, but I cleaned
mine out myself. Been fine for 8k+ miles since.
I took it off and back flushed it out with several kettle-fulls of
boiling water, blowing through with compressed air between. A load of
white ash, and some soot came out. I then refitted it after leaving it
in a warm place overnight to dry out a little. Apart from a bit of
steam when I first started it, it was fine. Cost? well how much to
boil up 10 kettles of water?
Took a couple of hours or so. The most difficult bit was getting the
clamps off the joints on the pipe.
The filter on yours, 2001, is what looks like the front silencer box,
it has a heat shield under it, and a sensor in the middle. This is
actually a heat sensor.
At the front end, and rear, there are little pipes which go to
pressure sensors, which is where the error message is generated from,
when they see too much restriction in the filter. You do have to be
careful to get these back in the same order.
The German diagram is actually for the larter model, where the cat and
filter are in one box with a flange joint to separate them. On yours,
the cat is right up on the back of the turbo, the box on the exhaust
only contains the filter.

 

So there you go Barney.remove it and clean it.

Many thanks Brian (and Chris). Very detailed description of what is required
to remove and clean it out. Since I took it for a 30 minute blat along the
motorway the warning has not come back again. I wonder if the filter has
regenerated? Still, if it comes back I can decide whether to dismantle it
myself. Many thanks once again.

 

probly needs a good run now and again.i bet it is used for short trips

 

That's right - doesn't get a good run out very often.

 

Do what i do with mine give a good hard run down to the south coast ,if
weather is good if not i give it a hard drive round the M25 as it does
help,

 

I actually live on the south coast so I will just stick to the M27 once the
road widening works have finished.

 

What that still going on taking time to do that.well it is the
english.ahahaha
