Goodmorning everyone,
I have a new problem with my kj, it goes into limp mode without giving errors on the dashboard, but from the control unit is the problem "heating regulation". You can give me some advice, as an error it is generic and does not result with a P0 type code ...

P.S. he does not always do this if I turn off the car and wait a few minutes for everything to return to normal.

It seems if there is a problem serious enough to trigger limp mode, it should also be setting a Pxxx code as well.

How are you determining it is a "heating regulation" problem from the control unit if there are no Pxxx codes? And do you have any more information about the heat problem? Like is it engine temperature, or something with the glow plug system, or... ?

could it be the fuel filter resistance connector? the error is B10B3 but there is no error with this code.

You can remove the relay, but it will set a code. It should not cause limp mode though.

I changed the diesel filter but nothing has changed I removed the relay and for the moment everything is fine. I expected an error in the control unit but nothing will be seen later

nothing to do even without relay the problem persists, what puzzles me is the lack of errors in the control unit after removing the relay
