Some of you may have seen my posts on here when my 2015 Grand picasso suffered the all too common adblue pump failure with persistently screaming pump and Service light on, engine fault light and urea light on.
Diagbox says leak/ low urea pressure.
It is worth noting that diagbox says pressure is 4 bar even when its actually zero.It does not...

Ive been told there are two types eolys, what goes in mine? its a 02 C5 2.2HDI 136 Exclusive hatch, been looking at Pat fluid DPX 42/176 is that ok?

Lets see what you've found, but as always, keep it family friendly :)

Revised January 2024

Here is a possible and relatively cheap fix that may resolve some RT6 issues that can occur as a result of the internal MicroSD card starting to fail. Bear in mind that this may not solve your specific issue, but has been known to resolve boot lockups or the 'check in progress' error. Flash memory cards only have a finite...

Hi everyone,
Two years ago I was forced to change rear hydraulic pipes on my ’09 x7 2.2HDi cause one of them leaks. Whereas the pipes was unavailable to buy here I decided to create substitute from original. I was working on it with my colleague. We tested almost 10 pairs during last year and half and we can now manufacture them for C5 X7

A burglar broke into a house one night. He shined his flashlight around, looking for valuables when a voice in the dark said,

'Jesus knows you're here.'

He nearly jumped out of his skin, clicked his flashlight off, and froze.

When he heard nothing more, after a bit, he shook his head and continued.

Just as he pulled the stereo out so he could...

Hi All,
Seems I have a new neighbor with a lovely silver Xantia with personalized reg plate.

Have not seen up close yet, so not clear on the specifications, also due to vague parking arrangements I don't know exactly which house is theirs either.

Is this anyone on here living in HP1 area with a Silver Xantia on a personal plate?

Admins, sorry...

The Citroën of one of my family members has a problem with the brakes, does anyone recognise the issue and know how to solve it?
Sometimes whilst driving slowly, when the brake pedal is pushed, the pedal does not give resistance, allowing to push it a lot further, and not actually braking immediately. Obviously this feels very unsafe. The car has...

Hi All

As per my post here: regarding a potential Timing chain conversion for the 1.2 EB2 / Puretech Engines fitted to many Stellantis vehicles like Citroen, DS Automobiles, Peugeot and Vauxhall vehicles, it now appears we are closer to getting a kit for the conversion.

Thanks to 'Scottish Car Clan' for posting this info and link to the original...

Michel suggested we have a dedicated thread for meeting arrangements so here it is!!
Please use this for anything to do with plans to get together so everyone knows where to look.

I'll start it off by copying my post from the other thread inviting fcfers to a lunch meeting on Tuesday. So far we have 3/4 attendees so I'll amend the booking to...

A post from a member who has likely suffered a Hard Drive failure on his NG4 Navidrive 3D system has prompted me to re-double my efforts in finding a possible pre-emptive solution to Drive Failure. The same can be said of the RT4 system with a HDD, although these units seem to have more issues than the NG4. Although the principle is the same for...

appears to be a Turkish supplier of hydraulic parts who is attempting to get into the markiet of supplying after-market spares for Xantia parts that are now obsolete. Their pricing seems very reasonable.

I have no other knowledge of the company.

From time to time we have reports that posts are submitted to this forum but they disappear after being submitted (as in they never become visible). It is sometimes reported that (frustratingly) the user had spent a long time composing the post.

I have recently seen a suggestion on another forum that a plausible explanation for this is that in...

Attention C5 and C6 Owners

Another member of the Forum recently had his C5 X7 LDS tank explode at a recent tyre fitting session, when the vehicle was lowered back to the ground.

For those unaware, the C5 and C6 should have the suspension raised to the highest position and the LDS tank cap removed whenever the vehicle will be lifted off the...

Just casting my my mind around the various films in which I've see French-built cars. Comes to mind:

2 CV in Pink Panther with old Peter Sellers

Then only vaguely are the cars in the Day of the Jackal, but there have to be some in Manon des Source, Les Regles du Jeu (sp?), but I don't recall any in The Duellists.

Any more/amplification?

THIS is why you must remember to depressurise .......... never forget to do it when working on older Citroen models

Strictly speaking, this isn't specific to French Cars, but as members often need to send 'bits' to one another, the following may be useful.

To send a Xantia radio, which is just a bit too large to be a Royal Mail 'small' parcel, the cheapest my local Post Office (very obliging) could do it for was £8 :shock: second class parcel post.

However, I...
