Fuel filter bleed procedure - C4 Picasso 2017 diesel

Post by danlat1415 »

Please can someone confirm the correct fuel filter change/bleed procedure on my 2017 C4 Picasso diesel?
VIN - VF7**************[VIN obfuscated, can be read by forum staff]

I used to have a 2014 diesel previously, which had a bleed pump button on top of the fuel filter housing to press on and off until it when hard.

On the 2017 it's a different filter housing with no bleed pump.

I've changed the filter by following YouTube videos, and turned the ignition on and off 10 time (not the engine) waiting 10 seconds between each press (on, 10 seconds, off 10 seconds etc).

I've started the car and it starts fine, but I've noticed the engine sounds like a pulsing noise (not the revs, but the noise it makes in the background).
I've not listened to the engine fully before, with the engine cover off - so I've not noticed if this is normal or not, or if there is air in the fuel line.
I don't know what air in fuel line symptoms would be.


Any advice would be greatly appreciated.
Thanks

That sounds like the right procedure. I recall ours was a but lumpy initially after I changed the filter, settled down after a few miles drive.
