Customer Question

Hello Simon and Welcome.
My name is ***** ***** Im happy to help / advise..
Given its only just started this this morning I imagine you have not had any checks / tests done as yet.. plus I note you say there are no warning lights / fault messages etc -
The first thing to bear in mind/ consider is when was fuel last added-- was it the right type - ie, petrol / diesel? You don't say which engine your C3 has - but putting an amount of the wrong fuel in either will cause this...
If its definitely not that - then again, as to faults , it depends on the engine fitted.. To save you time, ie - if its a petrol engine, most possible faults are a faulty spark plug - sensor, dirty air / fuel filter or , a common fault - ignition coil pack..
If its a diesel model - common faults that will cause this are dirty fuel / air filters - fuel contamination - faulty crank or cam sensor - EGR valve needing cleaning..
Those are the common issues on both types of engine.. Plus petrol engine suffer with this type of fault through damp / water in the engine bay for some reason - having gone through a large puddle for example - and too, they will judder if the fuel filler cap seal is faulty or the cap is loose..
So Ive endeavoured to cover several aspects to save you time..for consideration / checking.
Bear in mind though , unless its found to be something simple as above - then as the car is a 2013 reg it will be under Citroen warranty -and as such , other than basic checks - if nothing is found, they will need to connect the car to a diagnostic computer to check its controlled functions / computers etc to find your fault.. This would be FOC being warranty work too.
So work through as above -one way or the other with that you will get this sorted.
Let me know if I can help anymore at all or if there is anything Ive missed or you need something more..
Kind Rgds - MIKE.
