hello do you know if it is possible to delete a dtc p0171 from the ecu simos 9.1 thanks

hello claudio, is there a software appoisto for the dtc vw or dtc remover.

but I don't recommend the elimination of the error on the engine, especially with one as important as your own.

the P0171 - Adaptation of mixture out of the field maximum, lean mixture

now, you have not given us much info, and perhaps this is why no one has responded, but can I assume that the dtc is present because the car is also gas, and the lambda fails to provide the correct parameters for the adaptation.

if it has no gas system but it just goes to gasoline one of the probable reason could be that one of the injectors is not working properly.

in the first case I have the gas system is functioning poorly or been hurt!

in the second case, instead, you should check very carefully all the connectors of the injectors, surely there is one that does not pass good voltage.

the second case happened to me 2 months ago on a polo 6r 1.0 petrol.

delete the dtc on the ecu engine and a very bad idea.

I hope to check out state help hello -

I fully agree ! Very good opinion

facts map the car to the gas well and see that the issue is no more!!!

exact and what intendetvo, but I'm seeing very often that the companies series, at least around my parts, for the gas system, put a second ecu only for the management of the gas system.

view on a matiz last week, arrived in the workshop that does not put in motion to another problem.

what I don't know now if the map that is made for gas plant and adaptive, in the sense that it is retouched in a way that is suitable to go with the 2.

obvious , by the installer of the systems, I will say that the gas plants and methane with modern electronic fuel injection and consequently have an ecu that handles the situation, but the ecu is concerned only with the gas system.

I capitro. but mass in motion, and always petrol, and then switches to gas if you leave this mode??

I remember that the first car as the alfa 133, etc, you had to put into motion a petrol and switch to gas in marica?

in modern plants, and the same principle??

Identical and precise behavior. At a certain temperature passes gas

now I have clear ideas thanks
