having a problem with our citroen. it keeps cutting out, no warning just dies. This varies as to staying dead for anything between 5- 30 mins during which time if you try to start it the engine management light stays out. The car will only start if the em light comes on during the ignition process.

other times it's just a blip of no power, dead engine blink of em light and then all normal again - but for how long??? It's pretty scary on motorway when this happens and you have to make an emergency dive for the hard shoulder.

Engine management light has only stayed on with car running once- had codes read, came back as 0340- cam/crank shaft synchro problem- have changed both sensors, also changed the brake light switch.

Absolutely no difference.

Any one any ideas as to what else to check/replace?

Any one know what would cause the em light to stay out and so stop the engine from starting?

All help gratefully received, this is driving me nuts!!!
