Mark :

Hello. My name is ***** ***** I will try help you with this.

Mark :

Your first question is the one you really need to focus on.

Mark :

If the dpf is nearing saturation point then it requires urgent regeneration.

Mark :

If it doesn't get/do this soon then it can be very expensive.

Mark :

Because the dpf is a filter, failure due to saturation is not considered a fault and can be expensive to replace/repair.

Mark :

What you could try is an automatic regeneration. You need to drive the car on a motorway where you can maintain a constant speed of 60mph for at least 15 miles.

Mark :

If you cant do this then your local Peugeot dealer can carry out an enforced regeneration with their scan tool.

Mark :

Hopefully it wont be too late and the filter will regenerate ok.

Mark :

For the tyre pressure fault, you will need to have the tyre pressure monitoring system checked.

Mark :

This could be caused by either a slow puncture or a faulty tyre pressure sensor.

Mark :

The sensors are located inside the wheel/tyre and require specialist tools to check/replace.
