Fiat Doblo 2004 D 1.3 JTD fast idle

[wombi]

Fiat Doblo 2004 D 1.3 JTD
Problem. About 2 hours driving time, when the engine is really nice warm, the speed falls to 780 U / min. This can not build up sufficient oil pressure and oil pressure indicator light starts to blink.
Question:
For this engine, the idle speed be increased? If so how?
50 U / min would be sufficient.

For an answer, I am very grateful

Best regards

Hello
because no one has any idea about this problem?

Think you have a mechanical problem, oil light should go out at those revs, have seen worn timing chain wear through oil pump casing, need to
have checked before major damage done, how many miles has vehicle done ?
Have you tried changing oil & filter ?

Thank you for your reply.
The vehicle has 72500km gelaufen.Öl and filters are changed. In the cold is no problem.
If the car is long gone so if the engine is really warm, the speed drops slightly and then flashes from time to time, the oil lamp.

Still think is mechanical issue, when egine cold oil is thicker than when warm, depending on oil used,
what oil spec was used , 15w40 no good for example, if vehicle idles a lot things get clogged, is this a taxi ?
Maybe oil pick up issue, or could just be a faulty oil pressure sender switch, you really have to get it checked.
Maybe try replacing oil pressure switch, but maybe an idea to put gauge in to see actual readings.

Hello Mal126

The problem is that the speed on a hot engine of normal 860 to 780 rpm drops. Oil is 5 / 40.
I've also tried 10/40 but it does not change.
Oil pressure switch was gewechselt.Leider I have not measured the oil pressure, car is not here now.
On the basis of the low Km I do not think of a mechanichen wear.
At the temperature sensor can not lie I've ever replaced a trial basis.
I think the engine is hot at the injection amount is too small to maintain a constant speed.
Is there not the possibility to increase the Einzritzmenge something?

Hallo Mal126

Das Problem ist das die Drehzahl bei heißem Motor von normal 860 auf 780 U/min abfällt. Öl ist 5/40.
Ich habe auch schon mit 10/40 versucht aber es ändert sich nicht.
Öldruckschalter wurde gewechselt.Leider habe ich den Öldruck nicht gemessen,Auto ist auch jetzt nicht hier.
Anhand von den geringen Km denke ich nicht an einen mechanichen Verschleiß.
Am Temperaturfühler kann es nicht liegen,den habe ich schon mal probeweise ausgewechselt.
Ich denke das bei sehr heißem Motor die Einspritzmenge zu gering ist,um eine konstante Drehzahl zu halten.
Gibt es nicht die möglichkeit die Einzritzmenge etwas zu erhöhen??

Hello
I changed once the MAS LMM (mass air flow meter), and now the error seems to be fixed.

First thanks to all

Hallo
ich habe mal den LMM (Luftmassenmesser)ausgewechselt und jetzt scheint der Fehler behoben zu sein.

Erstmal Danke an alle
