Hello everyone,

I need to replace the car battery on my Citroën C4 (B7) 1.6 HDi, 2013 start/stop. The battery specs are 70Ah, 760CCA, AGM.

Does anyone know the best steps to follow for a safe replacement? Also, do I need to code or register the new battery after installing it?

Thanks so much to anyone who can help!

The N/S/F hub bottom ball joint has started rattling - but it's immovably seized into the hub. :(

So a replacement hub is needed to get her back on the road.

Does anyone know which other models used the same hub please?

Better still, does anyone have one?

I'll post in For Sale & Wanted once I know exactly what I'm looking for.

I've posted...

Hi, Does anyone know if I need to register a new battery in a C4 Grand Picasso 2016 so that it is charged correctly? I believe this is called BMS Reset. If so, can it be done without an expensive device & how? Or does anyone know of a reasonably cheap device that will do the job? I have a Xtools Anyscan A30M, and although I have seen videos where...

My apologies in advance if I am posting the same question asked and answered elsewhere, but 20 minutes of searching has not got me to a more correct point.

In ignorance, I never knew until the last few deays that there are several different types of Eolys fluid, and I have a strong feeling that I jumped in and bought the wrong stuff.

My (July...

Don't know yet exactly what broke to make it happen , but had a large coolant leak (more than 2.5 Liters went out)
The thermostat housing or other plastic tube is the suspect. Only Monday will know.
Anyway , my biggest shock was that unlike the previous C5 , this X7 doesn't warn about low coolant level :shock:
Could they do that just to economize...

I suspect he will get one :rofl2:
See the video and tell me you don't get the same feeling :mrgreen: :

With all the great machines he drives , an old activa was able to surprise him. I feel less crazy now :lol:

I wonder if it is from some member of the forum?

I recently bought. 2009 VTR+ Tourer with 2.0 HDI engine. The multifunction radio display barely showed anything, so I have now bought a remanufactured unit. The display is brilliant and everything scrolls and works as it should, except that the Aircon shows only the seat icon and 22 /22.. The climate control.itself works fine but nothing seems to...

Hello.

Good day all,

My (July 2015) C4 Grand Picasso II 2.0 Bluehdi 150 EAT6 Excl. has finally thrown all its adblue toys out of its tank at 82k, and is showing the dreaded P20E38 pump failure. I don't have the time to follow Stuart's brilliant home repair on his, which he has documented elsewhere in this forum, and my bank manager has threatened me...

I recently purchased a 2009 VTR+ Tourer, which has conventional steel springs. Carrying 5 people last night across bumpy Fen roads, the rear suspension kept bottoming out making the journey uncomfortable. I cannot find anything on this subject and there only appears to be one grade of spring available. Wondering how you would manage to tow...

Hi everyone,

I wanted to share and get opinions about a very serious incident with my Citroën C4 II (2013, 1.6 e-HDi EGS6) here in Sweden.

On October 28, 2025, while driving at about 50 km/h, the left front ball joint suddenly came loose and completely detached. The drive shaft was ripped out of the gearbox and gearbox oil started leaking out....

Hello,

can anyone with servicebox access help me get some info about my Citroen that I am trying to fix.

Thanks

Altough this is no longer available as a kit , I still have one on my car and am clue less as to when it should work.
A very help full supplier sent me a set of instalation instructions for a C3 Picasso- its wordless instalation instructions just pictures.

So, I have been blessed with a 2001 Dispatch, 93 hp 2.0 HDI engine (BTED w3, RHX), RPO 8950. 340000 km on the clock. Having now sorted out the easier-to-diagnose flaws (leaking head gasket, tank pump not delivering fuel under 1/4 tank), I am at a loss with this last one.
The car surges ever so slightly under small loads like gentle acceleration...

Car:
Citroen C4 2008 1.6 HDi 110 9HZ/80kW

Problem:
When idling after a cold start, it runs OK (i.e. steady rpm), but when coming home (or parking somewhere after driving) the idle is pulsating (about 800 rpm, then up to about 1000 rpm, then back to lower rpm, and so on up and down). Also, when driving the car it hesitates at some points. For...

Hi, (very) long-time lurker here, surprising myself that this my first post!

I'm on my second C4 Grand Picasso, a 2.0 HDI from 2009. I've noticed that is losing coolant from... somewhere, but not showing any other obvious signs of a bigger problem. I'm having to top it up from slightly above the minimum line every 100km or so, although it's...

Hello everyone
I'm new to the forum, I've been working in the automotive field for a few years, and we're always learning. These forums are very good for helping with problems with our vehicles.

Has anyone had a problem with a 2017 Citroen Berlingo K9, parking assistance fault (B1229)? I've already checked the fuses, wiring, and sensors, and I'm...

Went to view a Grand C4P today and captured two videos of idling, one cold and the other hot. From the noise do you think there's anything to worry about?
Also the lower part of turbo (compressor side) looks oily but certainly no dripping anywhere. Is that normal for these engines? The car has done nearly 90k, no cambelt changed so far.
Cold idle:...

Hello everyone. Had the C5 for 12 trouble free years until last week!! Unlocking the doors now sets the flashers blinking rapidly in a sequence of approximately 6 flashes then a gap then 6 flashes and a gap repeatedly until the car goes into economy mode. Same thing happens when exiting the car and locking with fob. Took it to main dealers and...

Hello everyone !

I have recently got the remote access key from my xsara 2003 stolen. I wanted to make a replacement remote but apparently it's not all that simple, and two car locksmiths told me that without the original remote it was impossible to find the signal for the key-less entry receiver.
A friend suggested me to just replace the...

We have just purchased a used 2024 C5 X … 1st registered January 2025…. And since it doesn’t have a cd player … like our old C5 tourer… can I use my classic iPod? However the usb socket in the front of the car is not compatible… it is a type 3 usb and my iPod lead ends in a type 1 usb. Can I use an adapter?. Or should I buy a new cable or even a...

I've searched this forum but can't seem to see this issue anywhere.

In my Citroen C5 X7 Tourer manual. It drives superbly at what I'd say are town speeds (up to 40).

At 55-70 it vibrates like a sh!tting dog unless the revs are above 2k. Its not labouring as such, just normal gear changes at just under 2k revs. When I get to say 75 it stops. The...

Hi Guys, fairly inexperienced when it comes to cars/vans, just wondered if anyone has had an issue with back lights not working in the winter months?
My break lights work, my fog lights work and my indicators work.
its just the back lights, it says running lights issue and my back lights turn off. (i then have to drive round with my fog lights...

Hi all,

Apologies if this is a duplicate - had a problem when the site kept timing out.

I had this problem last year during the hot spells and had a hint of it again today.

When the outside temperature gets very hot - e.g. today where the dashboard was showing something like 30 degrees when I got in - I have a creaking noise when I turn the...

Hello.
Sometimes when I start the car, I can't immediately turn off the eco function (start/stop), and the button keeps flashing. But after driving a little, I can. What does that mean?

Can anyone help me with wiring diagrams for ABS,ECU and START/STOP relay so I can check CAN lines?

Citroen C3 2016 no crank no start.
Codes are related to start relay based on description
Codes: P0685, P13C1, P0615, P16BA
VIN: VF7**************[VIN obfuscated, can be read by forum staff]

Is it possible that if the ABS CAN line is faulty, the ECU has no connection with the Start/Stop relay...

Hi everyone, first post so sorry if doing anything wrong. I have a xzara picasso and the radio works but is beeping every few seconds, from what I I have already found out it appears the radio needs matching to the car Vin via Lexia. There is a Lexia owners map in the forum of possibly people willing to help, I found a couple pretty close but...

Hi
Please dont laugh at me. I have a Valeo alternator that I've dismantled from my donor Xantia and I want to use it as a battery charger. I've installed it on a plate with a 3 phase motor to drive it. so far so good. now, my question is how to wire it. I've seen that it has 3 terminals - B+, D+ and a third one that I cant see how it's marked....

When driving my C4 (2005 VTR+) on Saturday evening it suddenly felt like the drivers seat was no longer properly attached. So on Sunday when there was some daylight to have a proper look I inspected it more closely, it seems like the bolt or pin at top of the lever/fixing that holds the front right of the seat to the lower part of the frame and...

Just noticed gear changes have become really heavy. 1st to 2nd is most noticeable.

Hello everyone,

I own a Citroën C4 Picasso (2016, 1.6thp) and I’m currently facing a strange intermittent electrical issue that I hope someone here might recognize.

A few weeks ago, the car had a serious fuel issue — the injectors were delivering too much fuel into the engine, flooding one of the cylinders. The ECU was initially replaced, but...

So, I took delivery of my C5 Aircross in September and quite enjoy seeing the trip data that syncs to my phone.

However, my phone broke catastrophically and I had to buy a new one. I've connected it but only see the data from the trips since. Is there anyway of getting the app to sync the trip data from the start?

Is replacing the seal a big job? Service department of the citroen dealership said it's an engine out job. Has anyone had experience with this?

Hello,

I'm not too keen on the seats I have in my phase 2 Xsara break. Especially I'm missing the armrest. I was wondering if I could source any better seats from another Citroen or Peugeot - are there any other model which would have the exact same wiring, plugs and bolt placement? I had a 307 phase 2 which had comfortable seats, unfortunately...

Hello everyone!
I need some help from this awesome community!

I’m having a problem with my Citroën C5 X7 with the 3.0 HDi engine. It all started when my rear strut began leaking heavily. All the fluid leaked out, and the car limped home on the lowest suspension setting.
I bought a new strut and sphere and replaced both parts without any issues....

Hi All,

Newbie on this forum as was trying to wade through another one, so firstly thanks for existing.

I have my first Citroen, a 2012 C3 1.4 petrol with Sensor drive Semi Auto box, saved from the scrapyard as IMHO it was worth saving.

It had coolant leak (bad)and very jerky unreliable gear change, so I basically paid scrap money for it, and...

I’m really confused. I’m going to replace the front fog light bulbs with LEDs. The user manual says P21W, but online and on YouTube they’re shown as H11. Which one is correct? I guess I won’t know for sure without physically removing the bulb. Is there any chance to find it out by VIN?

From the first kilometer in a brand new C3 Aircross (Engine PureTech 1,2 /100 EB2LTED) I experience a distinct hammering nose in low and medium RPM particularly during pulling the car from standstill and accelerating after gear changes.
