C3 1.4 (2002 Model)

i have scanned ecu with diagnostic equipment in a hope to find out what's causing the missfire...it came up with the coil pack faulty.this was replaced,and had no effect.a second scan came up with faulty injectors.i,m begining to think there is an ecu fault,because every time it is scanned a new set of fault codes come up.just wondered if anyone else has had these problems,and also if you know of any recalls for this kind of fault? any help would be greatly appreciated...thanks.

I had a Fiat that reported a faulty lambda sensor on the computer when the actual fault was 3 cut wires. Just because the computer can't get readings from a sensor does not mean the sensor or part is a fault, could just be the connection to it that has the problem.

i had the very same kind of fault on my last car.came up as a misfire on cylinder 3 coil pack changed fault stayed,car would misfire and then run perfectly in emergency mode.Afraid this fault remained for over 3 months basically the car lived at the dealers.the car was a vauxhall but they stripped enginge altered running temp changed all the sensors and ecu unit and also rewired the full electrical system all covered by warrenty but they had to admit that they couldn't find what was wrong only that by doing all of the above the fault went.It was very thursty on juice though.

 

Got rid of the car 3 weeks ago because the warning light came back on and out of warrenty i was not going to pay for all this work.The engine management lights can be difficult to fault trace but on the other hand it could be something as simple as a split pipe

 

My advice is to stick with the warrenty and get a copy of the reports /finding for future reference because ecu units are not cheap good luck...............

C3/C2/Pluriel with missfire:

 

Fault more than likely caused by water leaking from washer jets after they have been operated......dripping onto injectors.

 

The injectors have some moulding marks which allow water ingress and allow it to corrode the injector terminals.

 

Replace injector and screen wash jet with new seal.

 

Coils can also be troublesome...not as much as the injector though.

[iannez]

the drivers side washer jet drips water onto the injector directley below it causing it to short out and that then shorts out the coil. you always have to change both. if you get new injector you will see the holes ether side is filled with white sealer and the old ones arnt. i always remove other 3 and seal them up while i've got the rail off.

Hello everyone i have the same problem now my c3(2002) is at the central Greek Citroen Service for missfire too. It happens after A lot of rain. I have it for the same reason 2 times and they have change me a faulty injector the first time and they just made an upgrade the second, lets see if they can do their jobs and find that simple thing :D

[belial]

The news are bad :D the company tell me to change all four injectors. Price over 500 euro.

Is there something i can do for this thing not to happen again? Does Citroen knows about this problem? And if that happens because of them why we have to pay they mistakes .Sorry for my bad english i hope you understand my thoughs.

As i say it happens after rain. How i'm sure that it never happens again?

[belial]

I received my C3 with 4 new injectors= 436 euro. I told them about the issue with the windwashers leak and they have never heard anything about that.

I will try to see another service shop. Does anyone knows the parts number and how to ask it? Please kfk and iannez i w8 for your answers.

[iannez]

just ask them to fit new injector. its the one nearest the timing belt. that should sort it.

2 screen wash jets part no. 6438 V8 (in packs of 2). .....They come with a rubber seal
