Hi, recently received gearbox fault (service) on a semi auto C4 GP. Using Topdon it revealed P17BE -
Gear Selection Actuator Locking Control, Open Circuit and U1310 - Fault In Communication With The Gearbox Electrical Control ECU. Car drives and i'm able to select P R N D M. What I observed is that when I'm driving at around 40mph the service...

Morning all

Thought I would see if anyone has experienced a leaning Xantia.

Its a Hdi with non hyroactive suspension

I've noticed its lower on the RHS compared with the left by about 10mm. Tyre pressure on all corners are correct. When its at its lowest height setting there is still a lean. At the highest setting it measures about 15mm...

Hi I’m wondering if anyone can help. I have a Citroen berlingo 1.6 HDI van 13 plate. Whenever I accelerate hard or put my foot down in a high gear the engine either shuts off with the red stop light or it jolts and the engine light comes on and the triangle light. The fan then stays on when I turn the engine off along with the triangle light....

Hi everyone, I’d like to ask for your opinions on an issue I’m having.

After driving the car a bit harder and then stopping, I noticed coolant coming out of the expansion tank and some smoke/steam from that area.
I let the engine cool down, topped up the coolant and tried to bleed the system. At first everything seemed fine.
However, once the...

Hi all
Thanks in advance for any help.
I’ve taken my brake servo out and have snapped/ broken a pipe that attaches to the reservoir bottle.
I’ve looked on Citroen parts checker but unable to see the part required or from any 3rd party.
It’s a pipe about 6-8 inches long that goes from the bottom/front of the bottle to a steel pipe attached to...

Hi,

The horn on my 2003 Xsara has been intermittent for a while and is now dead.

I found a post on here regarding removing the air bag, and I have completed this by removing the housing top and bottom of the steering column (3 x hex screws) and using a small screwdriver I managed to remove the 3 clips holding the air bag in place. When I was...

2019 Citroen C4 Grand Spacetourer
Massage seats (drivers and passenger) were both working perfectly but last week the passengers side stopped working. No green light, no massage and no lumbar support adjust. A quick look underneath the seat and there's no obvious trapped wires etc. I'm struggling to find details of any possible fuse(s) related to...

Hi . I have a 2007 Citroen Picasso exclusive. Has a fault where the cambus is not communicating properly with ecu . And code reader says it’s the engine fusebox . I’ve changed both fuseboxes including the one over the battery . Still has the same problem . Saying bad earth to fuse box . Exactly where is the earth wire to fuse box ? Can I bypass it...

Hi, after replacement of rocker cover with gasket (today), a squealing / chirping noise is heard while engine is idling.

I found this post in the forum (to a Xantia) that had the exact same problem as I do.
They suggest it is blocked breather system.

Has anybody a drawing of the parts involved in the breather system for a C5 II 2005 2.0i 16V...

Wipers suddenly failed and the switch appears to have no power.
Looking for fuse diagrams to see if is a blown fuse.
Any assistance appreciated
thanks

Hello, I need to replace my steering rack for my Citroen C4 Grand Picasso MK2 2015 1.6 Blue HDi 100 hp. I believe my current one has this part number: 1635675480 but I found that it might be possible to replace with 1651349180 which from the newer model. My picasso is pre-fl. Are these interchangeable? Will I have any issues fitting the newer rack...

Hi!

I have a Citroen C4 Grand Picasso from 2015 in diesel, left hand steering. Last summer, I noticed that the AC is not as efficient as it used to be. First I thought that it just needs a service but then I noticed that passenger's side is getting a lot warmer air than the driver's side. Since the summer was not super hot where I live, I did...

Hi,

Does anyone know if you need to recalibrate the EGR after replacing it? Citroen Jumpy 2010.

I’ve replaced the EGR valve on a 1.6 HDi and I’m wondering if it’s just plug-and-play, or if it needs calibration/initialization with a diagnostic tool.

I’m seeing mixed answers online - some say it self-learns, others say it needs to be programmed.

Hi all I'm new here :roll:

Bought a 2012 C5 Diesel VTR+ NAV 120kW 163hp from an auction in January with 122k miles.

I get the invalid oil level on ignition position every time, car was low on oil when I collected it. Did a full service on it and it took over 6 litres of oil to get it just over the minimum level on the dipstick and I didn't want...

Hi,
No data sticker anywhere on my car, and trying to find Citroen recommended tyre pressures for this model difficult. Dealer even gives different info depending on who you're talking to

Online check tyre pressure sites often don't state for my reg.
Recent tyre change due to outside edge wear suggests I'm running incorrect pressures. Had been...

I put this at the end of one of my other threads but just wanted to post this here in case others search for the same problem.

My 2009 C5 X7 with a 2.0 HDi 138 260,000km kept throwing an ECL every time I accelerated hard and when we scanned the errors we found P0088 and P1166 which all related to high fuel pressure. I also had an Antipollution...

Citroen Gearbox cooler pipes.jpeg On January 17 2026, I bought a used 2021 Citroen C-Elysee 1.6 VTi automatic, VIN code: VF7**************[VIN obfuscated, can be read by forum staff] and engine number: 10KNAL0011097 with 77,792 kms, allegedly with full dealer service history, from the official Citroen importer in Angola, supposedly with a one year guarantee. It has since covered 6,000 kms....

Hi Folks,

I've recently bought a lovely C5-II 3.0 v6 petrol Carlsson Edition with some issues for a good price. Most of them are already fixed, however I am still struggling with a mystery.
The car came with engine check light on and the recorded error was P0344. Brought the car to a shop for complete aux and timing set replacement, and put...

Happy new year!

After changing front pads and rotors with success,

Hey everyone, I've got a quick question about my 2005 C2 1.4i

I've been getting an intermittent Check engine light, I used a cheapo Chinese scanner to read the codes and I got P0134.
I also looked at the engine live data and sensor 1 was showing a steady 0.450.
I checked the resistance of the heating element and it's within spec.
Is the next...

Which battery should I use? EFB or AGM?

I have a C4 SpaceTourer 2021 with a 1.5 HDi engine, EAT8 gearbox and start-stop system. Thanks.

Evening all,

Just a quick one (Hopefully :rofl2: )

My passenger side indicator light stopped working some time ago.
So... knowing it was a sealed light I purchased a new one and went about replacing it.
So I took the wing mirror apart in the normal way that is to replace the unit.
Put it back together & went to test it.... bosh.... still not...

Gearbox issues, jerky, noisy!

MOT flagged up an oil leak and there is a LOT around the gearbox. So I thought a top up!

Watched this video, and thought, easy enough

Unfortunately, I think this must be for a newer model, my car looks nothing like that, in terms of where the filler plug is.

Its a 2007 1.6Hdi semi automatic. Can someone...

Rather than complicate the other WOES thread with sphere talk, I thought it would be useful to keep this separate.

I assume my S1 1.9TD is non-hydractive because I have 3.5mm pipes.

So looking at the 1995 Xantia Mechanics Handbook I note that the spheres for the 1.6i, 1.8i and 1.9D have the biggest damper holes.

So I set about writing them down...

I'm going to be regularly carrying a long kayak on my roof, which needs its overhanging back end tying down.

I've screwed in a towing eye. I'd like to leave this permanently in. But understandably I now get a beeeep all the time I'm reversing. The display shows the obstruction is on the corner, so I think it's only being seen on that one sensor,...

Hi everyone,

I have a 2006 Citroën Berlingo (m59) 1.9D (DW8 engine, manual hydraulic steering) and I’m working on the power steering return lines. I need the metal pipe placed near headlight to the oil tank. I’m a bit confused about the OEM parts 401238 and 401356. I don't have the old original metal pipe since it's replaced with a 12mm hydraulic...

Hello.

Wish to check if anyone can share a video on how to remove and and reinstall with new C4 GP reverse camera unit? If have any image of exploded view and if I can dismantle the existing unit by trim open from the outside without removal the interior taligate cover.

Can someone tell me where goes VAC in and VENT? The middle one goes to actuator. I did like the diagram says. Big rubber one goes to left, actuator to the middle and the this one to the right. Problem is when i touch the thin one on the right, it has vacum and the big rubber thing does not. If i connected vacum one to left then the actuator rod...

In the time since then to now ive driven arround and the gauge has registered further down wards to 4...

Hi all
I'm trying to get my CX25 DTR T2 engine running (this poor thing has been sat on my drive for a decade). it ran when parked, but now won't start - fires momentarily during crank, only.

I suspect fuel delivery is the problem and have gone through trying to prime the system.

It's decades (plural) since I've had to do that, so I've forgotten...

Hi folks

My latest C5 is playing up ( my first Exclusive). The aux belt tensioner is rattling and jumping about at tick over, above 1000 rpm its fine. I have changed the tensioner, crankshaft pulley and belt with a little difference but not much. The alternator and aircon pulleys appear to be running straight and there is no play in the bearings,...

Hi,

I’m having recurring issues with my Citroën Jumpy 1.6 HDi (2011) and would appreciate some input.

Background:
The car went into limp mode with engine light and ESP light. It wouldn’t rev past ~2000–3000 rpm.

I read fault codes and found several EGR-related errors. I replaced the EGR valve with an aftermarket unit (JP Group). After that, the...

Hi, I need to remove the glove box on the passenger side of the C5 MK1. I have a VDO navigation system. I removed the DVD Rom, unscrewed the two top screws, then all the torx screws around the perimeter of the box, but I can't remove it. Inside the box, there is a black sheet metal that the rubber pin of the DVD Rom fits into. Is there any...

Hi

I have recently had local garage fit a new Citroen additive tank (genuine Citroen part) but they say that the software update is not working so the tank will not function ,and needs to be coded or something.

I hope that this makes sense and if someone could kindly advise on this issue, and or what to do that would be great. :?

Just wanted to post a quick comparison / review between a 59-plate 2L diesel and 60-plate 3L diesel C5 X7 (both saloons). They are surprisingly different cars. The 2L has been in my family since 2014 (bought at 8162 miles), I've been a passenger for 8 years and the owner and driver...

Hi all,

I’m looking for some help diagnosing an EGR fault on a Citroen 1.6 HDi (DV6 engine).

Originally, the car had a stuck EGR valve fault, so I replaced the EGR valve with a new Pierburg unit and cleaned the throttle body / air doser at the same time.
After doing that, the original EGR stuck fault went away, but I now have a new fault code:...

Hi

I have a C5X change of behaviour that I've noticed with the engine/ hybrid system. I have the Shine Plus PHEV

When I got it last summer the engine seemed to operate in a way I expected. With a flat traction battery the engine occasionally works off the smaller hybrid battery, with a full traction battery the car seems to try and use up the...

My C5 has managed to lock itself so completely that neither the plip nor the key work. I can probably get access to the engine area by removing the front undertray and attempting to release the bonnet, but how then can I wake the car up? Any suggestions gratefully received!

Evenin' all.

Had a nightmare of a week. Both Xantia failed their MOT. Stupidly, War Horse didn't need doing until 14th April but I thought it was 4th April it was due and so took it earlier than needs be.

It's not actually solid all round but it is hard. Front offside is fine.

Hello,

?I need advice on my 2013 C3 1.0 VTi. The car has been consuming a lot of oil lately (over 1L per 1000km).

Today, while pushing the engine at high revs, the engine light started flashing and the car cut all power. I had to let it coast until the light stopped flashing.

Since the car burns so much oil, I'm wondering if this is a classic...
