Citroen Pneumatic Suspension [C4 Picasso C4 Grand Picasso] There is much talk about this problem. No doubt you have already trawled the net for a glimmer of hope - like many others, to little avail. The pneumatic system as employed by PSA on these vehicles is sadly fraught with problems. 7 year old 64 plate cactus, 65k miles. Engine fault, service light, emissions fault, flashing urea light yesterday, range limited - all the classic adblue pump symptoms. Local garage diagnostics today £85, spoke to Citroen U.K., sympathetic but noncommittal until repeat diagnostics (repeat £) and report from local dealer. I have a C4 Grand Picasso (2008) and have a problem with the seatbelt warning. When driving along and I go over a pothole or bump in the road, the seatbelt warning indicator will come on. It is always for the same location - the nearside rear seat which is one of the two that can be collapsed to give larger bootspace. Location: Edinburgh. I have an 08 C4 Picasso VTR+ 1.6 HDi. Recently had fuel pipes replaced and garage tried to clear fault codes but could not get any power to the computer via the OBD2 socket to connect to the car. Have found out that there are 2 pins that should have power ie 1 and 16, but only pin 1 has power to it.

Hi all, I'm having several intermittent faults with my 2007 C4 Picasso 1.6 HDi. 1) Handbrake faulty 2) ESP/ASR fault (which I presume is linked to the handbrake issue) Both of these correct themselves if I turn off the ignition and start the car again but return, sometimes very quickly sometimes I can drive for quite a while before they return. 3.1-While driving. When the ESP warning light comes on when you are driving your Citroen C4 Picasso, do not worry, this is normal, it informs you that the ESP device works in particular when you take turns. The sensors send data to the computer which will analyze them and, if necessary, activate the electronic assistance systems. Don't bank on the Ford being any better. We used to have both a 1.6HDi Focus and a C4. It was the Ford that was in the garage all the time racking up bills for clutches, not starting and electrical faults. And the C4 was more comfortable and used less fuel. So we got shut of the Focus and bought new C4. Which has been as good as the old one. XP9xAH.
