Hi!
Does anyone know what the u3fff code on my 2017 Peugeot expert hdi 1.6 d could be?
It says ~ fuel high pressure circuit fuel pressure lower than the reference value
I’ve given it a recent service fuel filter etc.
could it be as simple as a fuse or sensor? tia

Re: Peugeot Expert HDI 2017 U3FFF fault code
Did you bleed the fuel system properly when you replaced the fuel filter? This has to be done otherwise expect issues.
There is a tool (a set of pipe unions) that is used along with a set of plugs in this operation. If you don't do it then you will have a lock which will probably lead to fuel supply problems that you are experiencing.

It's a temporary fault, does it go away and not come back if you clear it? It may have come on when restarting after the filter change, or it could have been dirty fuel filter.
