I wouldn't bother, its up to you.

My advice would be to remove the EGR valve and clean it by hand if needed. This way you can actually see if it was dirty before you started and you know its clean when you finish.

There are some instructions here https://citroenc3owners.com/diesel-c3-ti ... -t289.html

If you have a problem with the fuel consumption or performance you would be better off looking to find the fault that is causing it.

I used the Terraclean process on my 2 litre SRI Vectra. You recieve a before and after process emissions test which will show how effective its been at cleaning. Worked for me.
