See if you can get the codes read, your model often has a particulate filter and all that entails but not allways on the 2,0 HDi, it seems too much of a coincidence to not be connected.

If it runs fine and the idle is the only problem you could try idling it up some with the idle set screw on the throttle body it sounds like it may be a little bit out of time those toyotas have a fine lins on the timing.

SOURCE: citroen c crosser anti pollution light

Anti pollution light, I never heard of a Check engine light being called that.
Read on please.

Hello
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

That sounds like fuel pump problem. Check fuel delivery when cold and when war. Replace pump if the delivery is drastically reduced when warm.

You need to have the spare reprogrammed as it has an immobiliser chip that sends a signal to the cars ecu so if the ecu doesn't recognise the chip the engine won't start.

Citroen c4 judder


Hi Sarah
Believe it or not the thing that causes most of the running problems on the C4 is the brake light switch,It is located under the left side of the dashboard 4 wire plug,If your C4 is left hand drive then it will be under the right side of the dashboard,These switches fail and cause all sought's of problems including running problems,silly messages coming up on the dashboard,But the brake lights still work,The switch is very cheap 17 pounds in the UK and 15 minutes to fit.
