I've been having an intermittent issue with my 2.0hdi 140. The car always starts when it's cold, but occasionally when it's warm and I crank the engine it will fire once on 1 cylinder then cut out. If I turn the ignition off and try again it starts, if I keep the starter going it will start after a few seconds. I've connected up diagbox and I get fault code p0341 intermittent which is a cam sensor, it seems likely that this could be the issue, any thoughts?
