2.2 Hdi Estate 2002 Exclusive - My New Car

[slugworth1987]

Hey guys and gals :)

 

been trawling the forums a while and thought i should join the noble cause and sign up

 

I got me a C5 estate for £600!!! bargain, love it great car with lots of comfort and a sports button!!!

 

History of the car: 

 

purchased about 3 weeks ago from a nice couple where the car had been parked up for 2 years with no MOTI drove the car streght to the MOT station for an idea of what it needed, when i got it the cars battery was dead and had tyres of the wrong size on the front axle (205/55/16) these were replaced after its failed MOT.  The car failed on ESP + ABS issues, stop light faulty, no fog lights and a bad wiper.  The car was fixed enough to pass its MOT but now i want to fix it propperly after falling in love with it.

 

 

 

 

But the car has a few personality flaws i'm not a fan of (issues) all of them electrical because french car :)

 

 

 

 

My Electrical issues:

 

Remote central locking doesnt work on either fob - could be flat batteries but the lock button doesn't do anything in the cab either

 

front and rear parking sensors don't work - rear does make a beep noise when i go into reverse but nothing else

 

fog lights don't work - wired in an AUX light to the towbar to get it through an MOT

 

top stop light doesn't work - covered with gaffa tape for now to pass an MOT

 

rear position lights are really dim

 

alarm doesn't work and crackles randomly (serien in rear arch)

 

sometimes the heater on the PAS side blows hot air only (motor swap in glove box needed but can't find part)

 

rear glass doesn't pop open (solder joint?)

 

ABS + ESP kick up random error codes randomly then go away randomly - diag cable is here just need to plug in

 

Nav doesn't work even though i have the colour screen?

 

Trafficmaster doesn't work but shouts at me now and again

 

radio signal is terrible

 

Trip 1 + 2 system shows random mileage and journey time

 

button on the indicator stalk does nothing?

 

Video works now and again (is that a DVD drive in the drivers glove box?!)

 

rear tail height adjustment switch is broken (needs to be replaced)

 

 

 

Mechanical

 

crank pulley is dead - finding prices

 

cam belt needs replacing - finding prices

 

annoying squeak comes from a wheel at random times not sure if bearing or brakes

 

car seems down on power but i have no idea if it really is as i ride bikes and used to bikes that accelerate quickly - replaced air filter this greatly improved the power and car now revs past 3000rpm 70mph can sometimes be a struggle to go past (can hear turbo whine from bonnet possible boost leakage)

Sounds as if the car needs a good service. The wheel squeak is most likely the rears brakes - see the relevant pinned post on removing/cleaning the caliper to suspension arm joint, the rear window not working is common and a fix is on here, it may need a new diesel fuel filter to improve performance, there is a fix on here for the indicator stalk button, traffic master needs a subscription if you want it to work, could be a faulty/dirty earth point at the back left corner of the boot giving the dim lights or maybe a poor electrical connector on the light, top stop light could be a wiring fault between the rear door and the body, at the left end (gearbox) there is a plastic socket and ball joint on the swirl flap actuator that breaks and could be the poor performance/esp cause.

 

If you look at the C5 Technical section Common Problems pinned topic you will see links to fixes and on the other C5 sections pinned topics to the fixes.

Hey Paul

Thanks for the reply!

 

Ive fixed the remote fobs (reprogrammed the keys)

 

Stop light i've not looked into, dim lights fixed (corrosion on the connectors), cars booked in for new pulley and timing belt, ABS pump needed (fault code dictates the number 1 valve is not actuating and corresponds to typical ABS issues as the light now comes on at 30mph)

 

NAV works to an extent where the signal is found on Laxia and commnicates with the BSI but no options to set route available? 

 

Didn't think the stalk was faulty will look into that.

 

Been reading up on the common fault list and all seem like typical easy fixes,

 

Disabled the alarm to stop the random chirping and this fixed it using Laxia

 

car has started to hunt under light/steady throttle (1750-2000 rpm) but need more time to diagnose (doesn't do this on Cruise Control)

 

thing does need a damn good service the prev. owner didn't maintain it all all!!! so much water in the boot!!!

 

I found an empty relay carrier behind the o/s rear compartment looks like it should house a 30 85 86 87 relay all wires are OEM need a diagram to see what they do... 

 

going to replace the fuel filter this week while the car gets its new timing belt, tensioners, water pump, crank pulley and AUX belt

 

Cheers for the reply Paul ill keep you posted!

The relay carrier in the back could be something to do with the towbar electrics.

The relay carrier in the back could be something to do with the towbar electrics.

With oem wiring? The fog light relay fir the towbar is on the n/s pocket and uses a 87/87a relay switching between car and towbar fog lights?

Update time!!!

Ok so I changed the fuel filter, added some injector cleaner, used some EGR cleaner, did a FAP Regen (Forced) and the car now spins the wheels in 2nd in the wet! perfect!

 

Now has a new timing belt + tensioners, water pump, crank pulley and AUX belt.

 

Ran the diagnostics after the regen and cleared all error codes and went for a 10 min drive to allow the car to accrue fresh data

 

The car seems to have a few phantom faults as per the citreon list i found on google.

 

 

First off

 

function tests of stalks

Wiper stalk

Indicator Stalk

both work fine! the button on the indicator stalk doesn't do anything though?

Nav and Display - shows no faults yet Nav doesn't work?

Rear sensors - Thinks the trailer is hooked up... I don't own a trailer... but i do have a tow bar

If you remove the towbar wiring fuses see if that lets the parking sensors work since if a Citroen system has been installed it could be they are automatically disabled when a trailer is connected. Also look at the towbar electrics socket, some have a spring loaded pin that is wired to disconnect the car fog lights and possibly this is stuck in as if a trailer is connected which would prevent the car fog lights working and maybe the parking sensors - so could be a simple fix with a spray of wd40 and freeing the pin.

 

The dpf eolys additive level appears to be low, or if it has been topped up, the level has not been reset. However, on early cars this needed the additive ecu to be replaced so is unlikely to be done. On here people say the additive will continue to be dosed if the tank is not empty, despite the warning message, and the dpf will not block up.

 

It would appear the abs valve block has a fault.

 

Is there another diagnostic screen for the Nav and which will give info on the mapping cd installed ? The screen you have shown is an extra one if there is a colour display.  The HFr connection test is to see if the fibre optic is present - 'Checks that the fibre optic is indeed connected. First activate the function'

 

The images of the stalk tests have not been displayed in your post. On early cars it appears the stalk end buttons repeated the last navigation message - the lighting one for colour screens and the wiper one for mono chrome screens.

 

If the high level stop light has water in it then it could be a circuit board fault in it instead of faulty wiring and a new light may be needed. If you need a new one a bit of black sealant around the red lens/black body joint may help prevent it raining in again.

Update Time.

 

Sorry its been so long wet away and I work 4 on 4 off nights so not alot gets done while im at work.

 

SATNAV!!! all fixed found out... no disc in the machine... found the newest maps on line downloaded and burnt thanks to a GPS forum although it does sometimes tell me that im off map area i think the aerial is dead(amp?)

 

Towbar, yet to find the fuses for it and as its not in the the manual im going to assume this isn't a factory towbar but has been installed after market and has had relevant mods to the ECU/BSI to allow it function correctly (when new)

 

Top light: full of water to the point its swimming so this is I'm going to assume is dead and in need of replacement.

 

ABS: had a friend look at it an agrees the pump is indeed in need of a rebuild/replacement which will happen in due course, never owned a car/bike with it so i don't miss it...

 

Eloys: confirmed "empty" will be topped up as and when i can face spending over £100 on a consumable fluid...

 

thanks or the help so far guys and i hope these posts have been helpful for others

On the towbar, have a look in the 12N lighting socket and see if there is a spring loaded pin that would disconnect the foglights since this may be stuck in as if a trailer was connected. Or maybe the wiring connection is corroded. If so a bit of wd40 may free up the pin. This socket on Amazon has the foglight cutoff http://www.amazon.co.uk/Ring-Automotive-A0012-Plastic-Including/dp/B003V56YRY

 

Our 2007 C5 estate high level brake light was part full of water when I got it but it worked. I have read it is possible to just remove the red plastic lens and then seal it but when trying this it broke, hence a new one and I applied some black sealant in the gap around the lens and body so it no longer lets water in. They also have a design fault so it will glow faintly until the bsi shuts down. The official fix it to fit a resistor to its +/- connections but I have not bothered. The fault also existed on the new replacement light. I do not think this light is part of the MOT so any faults can be ignored.

 

If the eolys tank is empty the exhaust dpf would block up unless it has been removed/drilled through. If the dpf is in place the exhaust tailpipe will be clean metal internally, if not then the dpf may not be present and there is little point in filling up the eolys tank - except for the MOT test the dpf system should be present and working although the test is only a visual one so a drilled through dpf may not result in a MOT failure.

Good day!

 

ok so towbar: nothing obvious mechanically is in either socket

 

new fault: after 3 days the battery is weak and struggles to start the car, after 4 days the battery has no juice left to crank the car, by day 5 shes dead, this batttery is only 3 months old...
