Fiat Scudo - Depollution system faulty and other issues (fault codes inc)

[Due-due]

Hi guys

I am hoping you can help me. My ex wifes car goes into limp mode, engine management light on and her incar display shows:

• Depollution system faulty

• Direction Indicator(s) faulty

VIN: ZFA27000064099444

Using my MaxiDiag FR704 reader, it has come up with the following error codes:

P0472 perm:

Differential exhaust pressure signal. Open circuit or short circuit to earth.

P0495 perm:

Engine cooling funtion integrated into the engine control unit. Coherence.

P1457 perm:

Particle filter. Particle emmission filter absent.

PO299 perm:

Turbo pressure regulation. Turbo pressure measured too low.

P0470 intmt:

Differential exhaust pressure signal. Coherence on starting.

P0490 perm:

Egr valve circuit. Not enough egr, egr valve too clased in relation to the reference value.

U1118 perm:

Please refer to vehicle service manual.

P1693 perm:

Controlled engine starting and switch-off fault, Starting or stwitch-off requests not valid or absent.

U2001 perm:

Please refer to vehicle service manual


After clearing the fault codes, the following codes would stay: U2001, P1693, U1118 & P0473. All the other codes would return after the vehicle had been used.

Your help in sorting this out is certainly appreciated. I am no qualified mechanic.

As I am sure you are aware, the Fiat Scudo is the same as the Citroen Dispatch and the Peugeot Expert.

Regardless of similarities, I only support PSA-specific vehicles. Fiat have their own VIN which is different from PSA vehicles and therefore we can't use these for ascertaining the exact vehicle and systems, sorry. I suggest you try a Fiat Forum.

These can be read by Diagxbox/lexia, at least my clone.

Could be many things with these codes.

Is differential pressure ok? Turbo pressure ok? Is the DPF actually present?

What engine is it 1.6 or 2.0, model year, hp rating?
