ignition problem

friends 1.4 hdi 206 when I was running my car sometimes I noticed that the starter did not take over more than other vehicles. I use it until I clean it, I wonder if it could be from this or I have another problem

Could be related to the coil.

Have you looked at the glow plugs?

The starter is healthy, if the vehicle is running late, it may be from the glow plugs as the friend says, but if it starts to be cumbersome as if it is not starting, it may be from the battery or the starter. . It cost 90tly, repairs kept 40 lira coal, 20 liras have a plastic inside it changed it, I gave work in 30.
