sudden shutdowns alfa 156 1.9 JTD 115hp

dear friends,
yesterday evening, my young 156 with 180,000 Miles, I made a joke don't like.
In the middle of a roundabout ? off of the shot. After 2 attempts to start, yes ? off the malfunction indicator light engine and ? allocated then it turns off again after 500 metres, at the next roundabout.
Broken, I did make about eighty Miles for me to go back home without other whims.
In the diagnosis multiecuscan has detected 2 errors:
P1671 - Fuel pressure regulator;
P0191 - Diesel pressure control.

My friend mechanic told me that, ? to replace the pump immersed in the tank, since? the malfunction of the sensor in it (P1671), would give rise to the second error.

To someone ? gi? success?

Look, I have another car but I can tell you that the shutdowns imrovvisi can safely depend on the pressure regulator that is not v

thanks for the quick response, but this regulator ? an integral part of the pump immersed in the tank, or on the rail of the Rail?

I would recommend you remove the fuel pump and check the fishing if clogged then clean it in the pump immersed not c'? no sensor parts from the tank to check if there are impurities?, then to the filter and high pressure pump disassemble the regulator and clean it if dirty.. checked the pressures with a gauge, sometimes the problem is in the fuel oil dirt

ok, let? as I have suggested.
And' likely that you have ever done diesel dirty. It was happened to my wife several years ago with an old point type. It was turned off and did not want to pi? starting afresh. The fuel pump in the tank it was full of wax!!! And' enough to clean it and ? all went well.
But the pressure regulator diesel ? what you find in the flute of the rail, just below the sensor of the turbo?

the pressure regulator or the DRV is mounted on the high pressure pump with two torx screws, one on the rail or the flute ? the pressure sensor diesel

I Backgroop!the controller, you can verify the operation with fes/mes,but I doubt he will be the guilty one.check with a pressure gauge the pressure low,you need to have at least 3bar,if I remember correctly!any experienced user can? confirm and/or correct?thanks

I have already? done all tests with multiecuscan and all have given me a positive outcome!
Tomorrow I'm going to retrieve a pump low pressure, and then I'll know.
Thanks to all

Check it out first with a pressure gauge! Why? the risk of spending money unnecessarily! !

Sometimes it happens that the wheel cylinder pressure regulator blocks. Try not harmful and does not cost you anything verification.
You should turn with active diagnosis and check the opening in % of the control.
