207 1.6 diesel black smoke event

Hello, I think not to buy myself a 207 1.6 diesel vehicle. I looked at 3 premium package vehicles, and I saw 2 of them on the phone. By the way, the vehicles are about 175 thousand km in the meantime. I am not sure what is Aslı Astar.

Generally, this problem is caused by injectors, sir. Because the injector missed, it throws smoke in the first place and then passes. or sudden loads. Smoke throwing does not happen in well-maintained vehicles, my friend, my friend, 300000 km 308 1.6 hdi 110, he does not.
