peugeot 307 fault
tomm
The engine warning light has appeared on the dashboard display
along with a message reading "anti pollution fault "
They can drive the car ok and the performance seems normal but can anyone
tell me what can be causing the fault lights ?

The fault codes can. Anything else'd be a guess.

Yes, it's the MAF sensor which is in the pipe going from the air filter
housing to the engine.
Never rely on fault codes from the computer as they can be misleading to
unqualified
mechanics who only know to look the code up in a book. Experience is what
counts and
identifying the cause of the error code. The exhaust emissions light can
come on if the mass
air flow meter is knackered because the engine can't tell how much air and
fuel to mix. It
ends up pushing more petrol or diesel in than required. The sensors in the
exhaust side sense
this and report a fault. As it gets worse the performance will die off or
acceleration will
be nowhere near as good. At some point it will go in to an emergency mode
and use up
quite a bit of petrol.
If it had something simple like a blackened air filter it would be obvious
and would
probably not clear such a fault. After 3 years the filter wouldn't be
clogged up that much
anyway although it could look a bit irty due to the dust it filters. The
surface area is massive.
If you are going to have a go at fixing the car then I would look at a few
hundred pounds.
That's what a new MAF sensor is for modern cars as you want a genuine one
and not some
nasty copy. The MAF only lasts about 3 or 4 years anyway - or at least they
have in my cars.

Well it's the most likely culprit, but it could also be either o2 sensor,
either the sensor plugs, the cat, an air leak, an exhaust leak , a missing
fuel filler cap etc. Getting the codes read will be cheaper than a MAF

Which is why most of them will /guess/ it's the MAF sensor

Hmmm I would sooner rely on fault codes than your "expert" opinion.
IIRC you stated that "The piston probably has a hole in it." in the
thread "Running on 3" when the OP in that thread stated the
compressions were 150, 150, 142, 140 psi

Sorry, no.
I had an 02 plate 307 SW 2.0 petrol from new which randomly showed this
message and had to be reset by the dealer/AA.
Twice it also went into limp home mode whilst showing the message - once on
a French motorway. Never got to the bottom of the cause despite much
interrogation and parts swapping by several Peugeot dealers and after 12
months and 32,000 miles of aggro persuaded the company to send it back to
Leaseplan.
Out of the five Peugeots we've owned this was the only one that gave any
major problems. I pity the poor sods who bought it after!

Especially as he hasn't even seen the car, never mind been told the
fault code...!
