Hello friends, I own a 2005 307 1.4 HDI and I am struggling with a frustrating problem that hasn't been resolved. Now when I start the car (it used to do it when I first started it after a period of waiting, now it does it when I start it any time) it runs at half crank and there is a loss of idle and the car seems to die. I sometimes give it gas and get it going, but sometimes it goes out after 5-10 seconds, and after it goes off, it starts but doesn't start again. Even if it does start, I can barely get it started. Sometimes it gives an antipollution fault error and turns on the malfunction indicator lamp. It doesn't exceed 3000 rpm and returns to normal during the day. When connected to the computer, they don't get any error codes. The EGR was checked, the turbo was overhauled, the fuel filter was changed, the handlebar grip was changed, the air flow meter was changed. Many things were changed by trial and error, but the problem hasn't gone away. Something I've noticed lately, if I'm not mistaken, seems to happen when the fuel drops below a quarter tank. I don't recall seeing it happen very often when the tank was full, or maybe it's unrelated or I just missed it. I'm curious if anyone who has encountered this kind of problem has found a solution or identified the source of the problem.
