Is the depollution system on my Peugeot 407 faulty?

The depollution system faulty and engine light comes up on my Peugeot 407, also there is a slight fluctuation in boost pickup, seems like wastegate opens and closes, it has been diagnosed and had 2 new boost solenoids fitted but there is no change. Does anyone have any ideas ? Boost is good after initial fluctuations and drives fine overall.

Where does the piping go in a Peugeot 407?

Piping takes the vac to the brake servo and the turbo control solenoids. So check the small diameter pipe from the vac pipe to the turbo control solenoid and down to the turbo for cracks/leaks. But to be honest new pipe cost so little I usually just replace all the piping.

Why is the plastic pipe melting on my HDi 110?

Using global check pp2000 also suggests the fuel additive system is ok too. Why is the plastic pipe melting.

Upon removing the pipe at the sensor end I found the short rubber hose had split just below where the jubilee clip went on.

Is the replacement pollution sensor the same as the original?

The replacement sensor differed slightly to the original and i was led to believe it was’ improved’ and that they sold loads. however it retained the same connections. Refitting was simple just required some small jubilees as the original clips from the hoses were not reusuable in my instance.
