C4 1.6 petrol Stalling cutting out at idle when reaches normal temprature

Hi hope you all are well, joined the forum hoping someone will able to give some advice.

I have a C4 1.6 SX Automatic, its 2006 Model.


If you start the car from cold its starts fine and you can drive around however when it reaches normal temprature at junctions etc it stalls..

If the car is started from cold, as soon as it reaches normal temprature it will cut out and stall.



I have had code reader on it and no faults are shown. No warnings on dash.


I have checked the following to eliminate them..

Oil filter.. as some cheap oil filters the spring part can snap.. But that was all ok

Spark plugs.. all good. Oil all ok.


Checked the following sensors by disconeccting and seeing im they make a diference.


Coolant Temprature -- Still cuts out

Lambda sensors -- Still cuts out

Map Sensor -- Still Cuts out

Crank Position Sensor -- Replaced with new one -- Still cuts out.


I have further checked the fuse box... fuse 1.. etc all that is good.


The coils seem to be good .. no misfire..


Had a look at the black fuel relay. but cant say much before I swap it with another one


I have done a bsi reset aswell... still stalls cuts out..

Also checked the brake switch incase that was giving issues... but its ok


Anyone have any ideas at what else could be causing it to cut out at idle when it reaches normal temprature..


the only thing I can think about for me to check out is the fuel relay or fuel pump.. or maybe the coils are playing up when it reaches normal middle temprature..



I did notice that when you do the onboard diagnostic it says speed control fault.. could that cause the car to stall at idle? apparently that could be one of the wheel bearings abs part..

Help and advice would be deeply appreciated as dont know what else to check.. thanks in advance.
