Hello everyone ,

I'm a new owner of a 2012 C4 (B71) for a week now and a new member of this amazing forum.

unfortunately i already have 2 issues with the car:

1. an A\C condenser leak which was sorted for 550$
2. a new issue that happened this morning - The car beeped while slowing down , the
check engine went on and the message "engine fault -repair needed" appeared on the screen.

connected the car to a scanner erased the codes to see what comes on again - the car drove fine for a couple minutes and the same thing happened.

here is a scanner screenshot:

Do you have any thoughts about P0945 ? couldn't find any post with this code.

Thank you very much for your time and effort.

Hi Nathanial, were you ever able to solve this?

I have recently bought a 2013 C4 Auto and have had the same code come up when taking it to a Citroen dealer. They wanted £2400 to replace the whole actuator.

Is it possible that it's just a leak from the actuator pipe?

Thank you
