Hi! I have a 2009 C4 with 1.6eHDi engine, over the last week I noticed that it's been a bit 'odd' when starting in that the engine almost stops/stalls straight away unless I blip the throttle slightly. Occasionally it's taken a couple of goes for me to start. I put this down to the cold weather and thought nothing more of it. Yesterday I started hearing a 'knocking' noise as I drive - it would increase in frequency the more I revved the engine. When I got home from work I popped open the bonnet to have a listen and from there, the best I can describe the noise is a 'panting' sound. Anyone have any clue what this could be (and more importantly, how much it might cost to get it fixed!) Thanks, in advance, Tony
