Hello everyone. I am new in this forum.

I request help for my fiat van bent 1.9 JTD Multijet 105CV

The problem that the van has is that when it rises from the 3000 .... 3500 rpm
a yellow light is turned on in the control panel.

I carry the Fiat connect it to a machine and the light is already removed from the dashboard (it lights at the time of the start and then disappears, this is normal
but now it does not disappear, it penetrates on.

Can it be the Lambda probe?

This light, at the time of start

It


disappears along with the other control symbols


. Symbols that appear when giving the contact along with this yellow light, disappear when the engine is launched but this (no) remains on, I repeat is yellow and its symbol represents
an


engine
. that take the Fiat dealership as soon as possible "is to get fear" because the van works perfectly after this event, runs as

Hello, my company van is the same motor version, but at the end of 2005. And that problem gives it especially in winter with cold time, when the paraffins the diesel becomes densest. If you have the light on, which will come to the reservation, try to refuel a little gasoleum of the good, (it is not even bad to change the gas station) .. When walking about 50 or 100 km, the light goes out, or the next time you rip off the van. You may also have to change the diesel filter. All the best.

Hi, Lambda does not lead to being diesel, but it may be that the turbo pressure sensor (in the pressure sleeve, or in collector) this dirty or measured because it does not open the turbo download valve (or by breakage of the pulmon warn that you do not break ... It may also be that the EGR does not work well for dirt, and also as the partner has told you, that it can have water in the diesel filter, to eliminate this, purges the water through the lower screw of the filter. This is what I would look basically, greetings.

Hello! I agree with Ismael53 but an issue arises ... if I had overpressure problems, the command unit would enter into "emergency" mode and the firing fiscal van ... this is your case? What fault did you give exactly to Fiat's? Because I don't opt ​​for EGR dirty ...
