206 hdi motor diagnostic problem ....

Last week, the 2003 model bought 206 hdi x-line vehicles at 106,000 km. While waiting at the red light (waiting for about 3 minutes), the engine started to vibrate and stopped abruptly. I showed it to the authorized service in the bursa and they said there was a fuel hose problem and they changed it.After that, the same mistake repeats again because they said that a few parts in the vicinity (said its name but I can't remember it) must have complete maintenance. .. Can you help me about this subject? I am also looking for a really special peugeot service in bursa ...

I think they passed the hose on the head, I think the parts they told you about the problem.
