Rough Idle

[stephenhoughton]

My C8 2.0 hdi has developed an annoying problem.

The car starts 1st time every day. The 1st time every day the car idles roughly, almost as if it is going to stall.

When i drive off, there is an initial hesitancy and then the car goes.

When driving the car seems to be running under powered, mpg is about 34. I have only had the car a few months It was bought under citroen approved scheme and has a 12 month warranty.

Somtimes when i select reverse and start to move the car does stall.

After the intial 1st start with rough idling the car will start every time and idles much better ??

I have no fault lights up.

i have tried putting fuel system cleaner in the dieel and it did nothing to cure the problem.

Has anybody any advice as to what i can try to sort it out. I want to kbnow what the problem is, then take it to the dealer if it is covered, rather than take it in and they work on it all day, tell me the fault was not covered and charge me the earth.
