Renault Repair Questions? Ask a Mechanic for Answers ASAP
Hi, my name is ***** ***** I will be happy to assist with this today.In some cases, I may need more info to assist better.I apologize for any delay.
All of these errors can point to a failing DPF or restricted DPF.I have seen these before with a faulty DPF needing replaced.You will need to have the DPF tested by a facility that can test the operation and flow of it to see if it needs to be replaced.In allot of cases a plugged DPF will cause other codes to set like a pressure solenoid or sensor.

There are sensors in the exhaust that basically monitor the DPF, if one of these sensors are reading incorrectly this can cause this issue here.
If it is the DPF in some cases ( rarely in some cases ) driving at highway speeds may clean it out but in most cases, this hasn't worked for me and the DPF had to be replaced.
You would need to have a shop or exhaust shop test and replace it.

Unfortunately, my info is not showing the locations of them.They are usually under the vehicle in the exhaust pipes before and after the dpf and are usually screwed into the exhaust pipes.
