406 motor failure

Sorry, that the two messages were late, of course it does not influence it is a temperature sensor in the slopes, I understood badly at the beginning), another pressure sensor that there is is the pressure of the turbo, but I do not know that it has to do with the temperature ... it is rare that they do not know how to say the failure with the diagnosis, I will "investigate" better, greetings !!

Thank you, I bought an ODB and I'm going to look at it, since it also surprises me that they knew anything in your day. They told me that it was something that had to do with the pressure but I already tell you that it was the official house in Palma de Mallorca and as you can understand I was not willing to pay things that were not the cause of the error. The car is phenomenal except this little mistake that is remedied to the few starts later, something rare too.

Hello again, I have been spinning it and see: two hypothesis ..
Turbo electrovalve: when climbing Cuesta, the caudalimetro note load and sends a signal to open the turbo, this is in charge of the electrovalvelvula, but this, does not displace the embolo for being "grabbed in cold" ... and lights "

Aver Frio, the flow rate sends a signal to increase or maintain a pressure ramp to the ramp regulator, put the same thing that in the previous case, which does not displace and failure.
This are conjectures ... Look to see the Turbo electrovalve, (the one that connects by a sleeve to Wastegate Turbo) but in this case you would lack power, tell me if the engine fails when it turns on, greetings !!

Hello.
The following is referring to all PSA 2.0 HDI engines.

The permanent ignition of the motor warning indicates an important anomaly in the motor management device. The fact that time goes out a time indicates that the failure is transitory, and that the vehicle's own diagnosis car detects its disappearance.

The main causes of ignition in this motorization are:
- Stages of injector command
- Injectors
- High fuel pressure collector.
- High fuel pressure regulator
- Pressure surveillance stage prevailing in the common ramp (switchboard)
- Airmeter.
- Power lines of the captors

Hello everyone, my opinion is that although the EGR is likely, the symptom would become much more recurrent over time, not 20 times in 4 years. In my opinion to diagnose a problem as intermittent as that, recreate failure conditions (cold, slope) and immediately when the malfunction is produced to know with certainty that malfunction detects the engine control switchboard. The other that symptom of loss of power due to dirt generated by the recirculation of exhaust gases is increasing gradually with the passing time. Ultimately if the switchboard encloses the malfunction witness, independent that after 2 starts the witness of a breakdowns (the detector that the failure is not present at that time) is saved in its historical memory the code of breakdowns detected by this one. greetings.
