Fiat Croma 1.9 jtd DTC limp mode

[pcbox]

Hi

Very unusual problem... Car goes for half a day totally okay, than throws P0091 and car goes in limp mode until you turn car and turn again....We already replaced all regulators, last option is also ecu to be faultx

Can this fault be erased, but that wont be enough, because on this car there was made full dpf off with some ecusafe and we did not find the right problem because car was not showing all dtcs...

So I please someone if can disable fault with LIMP mode off to try if it will be enough and maybe there will not be needed to replace ecu.

The file you attached is stock, no dpf off there.

Used dpf was put on car and programmed to stock map. This is the only fault which came up... And with this map also limp mode cames... Can this limp mode be removed from file?

can be removed

I think your problem is not related to ecu. You should check wiring. What diag tool are you using?

Please made it off if really possible

Original file is attached. We replaced fuel regulator on pump and on rail, sensor on rail. Also replaced fuel pump in tank. Wires to regulator are fine, checked too.

high pressure pump faulty or too old diesel filter

Fuel filter also replaced... High pressure was replaced last year by the owner... And it did not solve problem... They are driving for a year and half like this
