DPF Diagnosis Case Study Citroen Nemo

How we go about diagnosing a DPF and some of the associated parameters we need to check in order to determine a cause of the blockage.
Here we have a Citroen Nemo with a very clogged filter. The job should have taken about half the time but I ran into some technical issues.
This is by no means a thorough 'How Too' guide, as all systems are different and to be fair knowledge and technique in understanding, diagnosing and repairing these systems takes allot of time and money to gain.

I would like to say thank you to anyone who watches my videos and sincerely hope they help you in some way.
Obviously if you don't want to take on this job yourself your friendly Diagnostic Specialist guy (that's me) is more than willing :)
