2009 Citroen C5 tailgate self opens

Seems to be a common fault going by this .

Citroen C5 2.0hdi tourer 2008


I have covered 7,500 miles since December 2008, Only complaint is the electric tailgate opens on its own when I am away from the vehicle in my office or shopping, I believe there is a design issue with the keyfob as it seems to easily operate from inside my pocket whilst I am working. Have other C5 tourer drivers experienced same? It’s a serious security issue as it leaves the car wide open with no alarm sounding.

We have several C5 Tourer’s on the company fleet and all (mine included) have suffered from the "self opening" tail gate problem. There is a basic fix, ask your dealer to disconnect the button on the key fob. This is done by plugging in their diagnostic unit and blocking the key’s signal, the tail gate still opens and closes off the buttons on the car - Andy Leicester from England

My tailgate keeps opening by itself and I had my car robbed as a result, but according to Citroen UK this isn’t a problem anyone else has experienced! I think the car is great, but based on my experience and Citroen’s lack of after sales care I won’t have another one - Gary Scott from Ayrshire

Did you get this fault fixed ?

I seem to remember it could be a micro switch or a mercury switch inside tailgate, please let me know what fixes it.

push button on mine was faulty caused by water ingress citroen dealer charged £10.87 plus vat for part - was easy enough to fit and cured problem, used petroleum jelly on contacts for wiring to prevent re-occurance. " JOB DONE !"

I'm driving a 2003 model and had the same problem. I found out myself that there is an easy fix. The knob for opening the door is stuck. Move it back to the normal position.
If you open the boot you can feel the knob moving up and it can get stuck up there.
