Hi,
i have a Peugeot 307 hdi 1.6 90hp. It was produceed in 2006 and it has about 170 000 km. In the morning I started a car, it was cold, like normally i wait then turn the key and engine had strange noise, and RPM were uder 1000 and were not contant. Then i press on the gas pedal and there wasnt any noise. When i let engine normally the noise started again. After 3 minutes there wasnt any noise and I could drive normally.
I wonder if it is something wrong with gas ?

Hard to suggest too much without hearing the noise, but I suppose it's possible that an injector is leaking excessively, small amount of air in the fuel or even a glow plug problem. How does the car idle when it's warmed up, and can you post a video please? hope you get it sorted.
