Peugeot 607 2.0 136km HDI 2008 Diesel: Engine Self-Diagnosis Light & Emission System Malfunction

I have Peugeot 2.0 136 km HDI (year 2008), DIESEL , but today when I went to church I noticed that it wasn't going out Engine self-diagnosis indicator light



As I read in the instructions, this indicator:

Quote:

It should go out 3 seconds after starting the engine. Its blinking when the engine is running indicates that the injection or ignition system is malfunctioning. There is a risk of destruction of the catalyst (only for gasoline engines).
A continuous light of the indicator indicates a malfunction of the exhaust emissions system. Consult a PEUGEOT dealer quickly

When I came back we went to check it again and in fact the indicator is on and there is an error message on the monitor that the emission system is out of order.
However, before evening I went to start the car again and everything OK, the indicator goes out and there is nothing in the error status. However, I'm afraid it's a sign that this problem will come back. The question is what does it mean how to deal with it? Someone worked on such or similar problem in Peugeot cars? Maybe someone will advise me to fix this.

Do the diagnostics and write the error code, look at the real then all else can be said otherwise it is a divination of coffee grounds.

But how do you do computer diagnostics? The brother has this set bought it in China plus the program got the one they have on websites and a really good option, but it must be done by the brother so maybe you will know something more from such a preview.

That's the best service.

Well, we did the test with the program they use on Peugeot websites and here's the report, but it doesn't tell me much.

The engine controller sees too high a boost pressure although the solenoid valve is only driven by 1%.
There can be several reasons: damaged boost pressure sensor, shorted its signal to plus damaged turbine control solenoid valve or stuck turbine geometry.
You exclude the first two (if the error occurs every now and then) by looking at the parameters with the ignition on and the engine not running. Now you can see that the set pressure is lower than the read pressure. If the same goes for the engine not working, then there is a problem in the sensor or installation. If it is similar or read is smaller than the set value, these parameters should be observed when the engine is running at low speed. If they are similar, the problem is rather in the jamming geometry of the turbine. If at low speed the read pressure is greater than the set value, as can be seen now in the appendix the faulty solenoid valve controlling the turbine.
As for the first mistake, I do not know if sometimes it is not about a small amount of addition to the particle filter but here someone would have to say what has more experience in the PSA group.
Unless you once ran out of fuel.

It is best to clear all errors and make a new reading when the lamp does not go out. Some errors can be caused by a crash that happened some time ago and is gone.

I have the impression that you also have to replace the flowmeter because the computer sees -49 ° C, and this has not been so recently
