C4 (2009) Ehdi Engine Noise

[devoidx]

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

Welcome to the forum.

 

A panting or chuffing sound could be from a seal leak of a fuel injector to the cylinder head with the noise being escaping exhaust gases. If you remove the engine cover, have a look at each injector to see if you can hear the noise and also for any signs of oil/carbon at the base of them. If it is this then the sooner it is sorted the less chance of the injector becoming stuck/difficult/impossible to remove.
