ESp and DPF faults C4

Unread post by luk_wro »

Hi,

I have 2 main issues with my C4 Grand Picasso 1.6 HDi semi-automatic 2011.
The first one is an ESP fault, after changing tie rod end in my car and setting up axis alignment I start getting ESP faults. I check it using Delphi Scanner and it shows the:

- Steering wheel angle sensor; incorrect value received
- invalid data
- Intermittent
----------------------------
- Engine control unit, absence of clearing of the ASR/MSR reference value
- Intermittent

Second one is DPF, I change already EGR valve (mapping done) as it was showing that is not working, that`s gone. Also DPF differential pressure sensor is changed. Unfortunately i still have fault:

P1490 - Particle emission filter, overloaded
- Permament
------------------------------------------------------------
P242F - Particulate filter clogged
- Permanent

Any ideas? I should change steering wheel sensor and DPF ?

Normally the ESP can be reset by holding the button in for 5 seconds.

Yes I ask the stupid questions, because normally it is that simple.

The ESP system will likely need the steering angle sensor re calibrated since the tracking has been altered.
I would imagine your Delphi kit can do this.

That has nothing to do with the system faults Ryan. Holding in the ESP button on older vehicles just disables ESP temporarily, but it will kick back in once a certain speed is reached or when the ignition is switched off and back on again.
Please note, I'm no longer active on the Forum, so won't respond to messages.

I did it twice. Decalibrate and calibrate again. ESP fault back after a short distance.

Might have been worth mentioning that?
