French Car Forum

Hi guys, not been on the forum for a while but I've got a weird problem which started this evening.
When i am travelling along at about 30ish and i put my foot on the brake peddle I get the same bong as when i put the car in reverse.
Any ideas what i should check ? I'm puzzled by this one. :?

Hello.

Recently purchased a 2008 C5 Exclusive tourer with a host of problems. Fixed everything but the air con is fighting back!
Upon receipt of the car the air con was not working so I had it vacuumed out at a friends garage. We left the car for 2hrs to be safe and the vacuum held perfectly! We pumped in 630gms of gas (£40) and away to go, the...

The oil low message appears regularly on my C4 so I regularly top it up.

I finf the dipstick very hard to read though, it always seems to show oil on the marker but I once took it for a service and was told it was completely empty.

How much oil should I be putting in, it take 5 liters I think but is there any way to tell how much is in there?

Hi are there ways to improve the sound of this model? I'd like to make it you know...like a true 3.0 twinturbo should sound, deeper, stronger (not acute though), any suggestion? thanks!

I have a '97 2.1 TD Xantia I had problems with keypad code recognition and iffy no 1 button.

I have read all the threads in this forum about this situation, I have managed to change the code with great success for about 5 restarts. Now I just have both red & green lights on the display. I have done the quick fix, open/close door, ign. on, code...

I will try in short to explain my problem here...

C5 X7 163HP 2010 Tourer

This part (vacuum solenoid) from Throttle control manifold

was unattached (because it easily can come off), for some time, so my throttle flap did not move correctly... During that time I had an error P2141 (Exhaust system faulty), but nothing more, and...

Howdy team...

Looking at buying a 1st generation C5 2.0 HDi 4-Auto Wagon, seems to have been well serviced by citroen garage and got 120,000km on the clock. I've read the buyers guide, guess sphere's could be getting to the end of their lives, would much much prefer to be a manual rather than an auto slush box, but few manuals around, and to tbh...

Hi guys, first ever Citroen, well first ever french car tbh. I really like it, everything works except the airbag light is on the dash and the airbag pretensioner warning has come on, I need this diagnosed for the warranty company but worried they won't pay out and I'll be left short paying £100s for the diagnosis. Has anyone got a Lexia I could...

Hi, mechanics - do these symptoms suggest a potential cause?
My 2003 turbo-diesel Relay has long had a habit of starting perfectly - then beginning to smoke and bog down after a minute or so. Driving under load always quickly cleared it, and it ran perfectly then.

However! Yesterday, it began to smoke VERY heavily soon after startup. Again, I...

C4 Picasso 1.6 HDi 2013 model mk 2 it is auto or semi auto...it has a lever on the steering wheel and two paddles + and - on the steering wheel.
The lever positions are R, N, A, M
in M you can use the paddles.

I moved the car reversed into a space. Then turned it off. When I turned it back on the car started because the lever was in N position....

Failed mot on brake imbalance. I was expecting there may be a problem with setting up the brake compensator front to rear, but in fact the imbalance is across the rear axle !
So question is, is this likely to be a cylinder or shoes or could it be the dreaded compensator ?
Also, I was considering converting to rear discs, any advice on which...

Hello guys! I have some problems in my 1998 Citroen xsara 1.8i v16 manual gearbox, Xu7jp4(FLY).

1. The Fan blower sometimes working and sometimes not. The connectors are fine, the resistor works. I checked the circuit going to the resistor and it gets 1-3 volts( not enough to move the blower). When the blower works the resistor gets 12 volts....

Hi there,
I was wondering if I could have a bit more help than what I've read regarding the electrics.
I have fitted the towbar and am now going to attempt the electrics. 7pin by the way not 13pin
I have a bypass relay which I am going to use. I have two black wire that goes from the 7pin socket
I realise that one black wire is going to the left...

Hi I have c2 1.1 with sagem ecu, the problem is that when you drive the car more than 4-5000 rpm it goes like in limp mode and you need to wait a while for the car to start going again. The codes on diagnostic are p0300 and p1336. I have put new spark plugs, coil and crankshaft sensor. Do you have any suggestions?

Hi All,
Not sure if I have a problem or not......
I don't think my air-con is working............
Heater works, turn cabin temperature up, blower gets faster, car gets warm, turn temp down, fans slow down a bit car gets cold, but not as fast as it has done!
High pressure pipe under bonnet gets cold with engine running , therefore system is full,...

Hi all. First post here. I've been driving my C4 (1.6 2008) for a couple of months now, and it has developed an intermittent squeak when the accelerator is pressed. It's external, not the pedal itself. I've done some searching, but can't seem to find anything that sounds like my situation. This squeak occurs every time I press the pedal, and lasts...

Hi all

So now have replaced alternator and idler tensioner. Everything seems to be giving up the ghost one after another?!

Power steering pump is making a right grumbling sound when I listen with a screwdriver? Is it bearings or the pump on the way out? Easy to get hold of and reasonable price?

Also while down there with engine running the...

Hi Guys

one of my keys i kept in the glovebox decided it would only work the remote locking / unlocking but wont start the engine. Message displays Antitheft fault. I have tried the hold lock button in the ignition and disconnected car battery to see if anything resets but still the same.

car is citroen c3 2007 petrol and flip key

Any ideas why...

As per the title I have a coolant leak on a Citroen C4 Picasso, with a friend I have tracked the leak down to a pipe on the right hand side of the engine that comes out of the back of the water pump thats connected to the out pipe from the radiator.
I would like to know more about where the pipe goes and what its called. A diagram of where it...

I am buying a towbar for my August 2004 Xsara Picasso Exclusive and am unsure about what I need to do regarding the electrics.

I have read that I might need a special fitting in order to cope with multiplex wiring. Can anyone please confirm? I have seen that it's needed for post 2003 cars, but on another website it says post 2005. If it's any...

Whilst fixing another issue, my bonnet catch has decided that it no longer wants to work.

I can pop it open 2 inches with the interior handle, but the little tab underneath the car doesn't want to work.

It feels very stiff and there is definitely resistance, but it won't release the bonnet. It almost feels like it's stuck somewhere..

Any ideas...

Hello!

I have a 2009 C5 that won't start. Starter kicks in, but it won't fire. I'm really struggling with it and not sure how to fix it.

There was an intermittent problem with the cruise control where it wouldn't enable, so plugged it into my friends computer and had the following errors:
P1607 vehicle speed limitation
P1671 cruise control
P0341...

After moving in the shadows of the forum for years, I am stumped.

My C5 is lacking power. Hardly no acceleration in lower gears and really loses speed when going up hill.

If I unplug the connector to the mass air flow sensor, a pollution fault light comes (to be expected!) BUT the car runs perfectly like a rocket.

So, I go away and order a...

My 2004 c5 2.0 hdi (110 bhp) (77000 miles) has suddenly developed a gearbox whine in 4th & 5th only. The whine is worse in 5th than 4th and it is worse between 50 - 60 mph. Below 50 mph the box is quiet, above 60 mph I think that there is a faint whine, but it is hard to tell accurately due to the increased road noise.
The whine is only there on...

Hello
I wonder if anyone has had this experience or if anyone knows this please:
Can a digital speedo (the one with screen) and radio be retrofitted/installed into an SX?
Do both unit types use the same cabling to feed on information etc?
Many thanks

And finally.

Could I ask a favour please Marc. The previous owner of my C5 has just turned up on my doorstep with the missing locking tow hitch (Witter). Frankly I didn’t think he was going to deliver but....... now that he has I would like to use it.
I note it has a 7 pin socket and I would like to upgrade it to a 13 pin socket. Could you point...

Hi, Has anyone any tips or advice for replacing item 3 (longitudinal link I think) Is it best to replace as a whole or just the bushes?
On mine bush 11 has failed and item 3 contacts the hub carrier item 20 causing a knock. You can just see the point of contact in the photo.
Will the nut (71) be inside the car?
Many thanks
Jim

I have a berlingo hdi van (53 plate). Whenever i accelerate over about 70mph an engine light comes on with a beep and the power dies and drops me down to about 50mph and wont accelerate.

Hello.

First of all, I apologize for translating with google and for help.

I have a car problem. Xsara Picasso 2.0 HDi 66kw year 2001 TYPE engine RHY.

When my daughter was driving with him. Last month she used it too. He switched off while driving. Only this I know to say.

We dragged him home. Calling one and the other mechanics with various...

I need a wiring diagram for 2015 DW10FD 2.0 Hdi diesel. Or pin chart to identify wiring around engine. (Especially TPS / accelerator /ECU.)
Anyone help? That engine has been out since around 2014 or even earlier in the C4 Picasso so must be one available by now?

In an attempt to avoid what might become the need to replace the turbo on my 2009 138 2litre hdi, I have replaced the turbo charger pressure regulation electrovalve (part no 1618X2) and also the boost pressure sensor (part 1920CZ). Ignoring the fact that I managed to break the second sensor - it is a very tight fit in the hole in the manifold and...

Citroen C3 1.4i 2007- VF7**************[VIN obfuscated, can be read by forum staff].
I am trying to trace my missing voltage from the Throttle Position Sensor -track 1.
Could I have some help please with the wiring of Intake Throttle Valve and the Accelerator Pedal to their termination at the ECU. I guess that's here they finish up!

I've just bought a 2009 Citroen Nemo and I'm wondering how to fit some roof rails. Has anyone done this and if so is there a guide orvideo anywhere that you know of please? Thanks in advance.

Hello. Have 2006 1.6 Hdi C4 which has been sitting in yard for a number of months. Started it yesterday and ABS warning comes on. Checked on a computer and it describes fault as Solenoid Supply Valve . Does this mean I need to change ABS unit? Or could it be the wiring? If I need to change it does it have to be coded in?Thanks

Dear friends, experts or analysers,

I have an issue with my car that I have not succeed to find a solution so far. I want to ask for your help. I really like to hear what you think. My car model is Citroen semi automatic C3 2006 SX 1.4i Sensodrive. My problem is exactly that when I shift my car gear's Rear to Null or Rear to Forward my car's...

Howdy folks. I have a 98 TD Xantia Hydractive which has developed an odd (hard to think of an appropriate term or analogy) corkscrewing motion when taking left-hand sweeping corners at speed. On turn in it loads up on the RHS of car as the weight transfers to that side, then it suddenly tightens and does an over-steer inducing roll which pulls the...

So the Xantias let herself down and decided to stick oil into my nice new rad, matrix and the rest of the cooling system. I bypassed the oil cooler and flushed however there is still a lot of oil collecting, enough that my top hose was solid (think the stats jammed up with it as well)

I'm certain it's HGF, but looking around it seems to be a pig...

1.6HDi, DV6TED4 engine. The car failed MOT on excessive smoke. It off the scale. The engine was hot and I had dipethane already added. TBH you can see plumes of black smoke sometimes in the rear view mirror. I'm not sure where to start air filter is new and no leaks on inlet side. There is oil building up in the air intake chamber after the turbo...

Hello.

I’ve noticed a feature on my recently acquired 2008 C5 exclusive tourer. When selecting reverse gear (automatic), the climate control fan speed increases. :?

Can anybody shed any light on the reasoning behind this?

Thank you. :)

Hi Everyone

Just a quick question, can you replace the bearings on the auxiliary drive belt idler pulley?
Getting strange noise when traveling and have used screwdriver to listen to the drive belt pulleys and it's either the idler pulley or alternator.
However no effect on lights or warning lights so I am starting with the cheapest.
Have removed...

Hi, I,m hoping some of you lovely people can help me.

I have a Grand Picasso 2.0 litre HDI Diesel. 2007 with electronic gearbox.

I had put some diesel in at Asda and I drove about a mile accelerating uphill, the power dropped off and the car went down through the gears. I got to the side of the road and the engine stopped. It won't restart....
