2004 1.4 hdi 307 Failure

2004 model 1.4 hdi 307 "troop tool engine" (there is a continuation of the fault, but this remained in my mind, it was in words like cool) started warning warning on my front panel with the last 2 weeks with the stop warning on my front panel and again the red grid at the bottom I could not solve what happened on the front panel. The line line or a warning light that looks like a warning about water started to light up when I first started the malfunction, if I ignored it and walked after a short time, but today, when I started the starter, there was not even a click sound in my car, there was not the slightest problem in electricity, when the starter started, the battery showed signs of dead battery. I did not work 2 times I did not work did not work 2 - 3 minutes later I took the starter instantly and worked, I did not understand what happened to my vehicle, I would be glad if friends who have experience in this matter or who know the fault I described in myself halfway.
I searched by typing "troop tool engine" on the subject, but I did not come across a topic, but I'm sorry if I opened unnecessary topics.

the same fault happened with me. probably a little leak somewhere. When I opened the hood, the water tank on the left was out of that water. I took it to the service.

check the coolant, if there are leaks, follow the water continuously after completing it. especially the octopus hose can wear out over time due to vibration in diesel engines.

As you said thank you for your help, the cover of the tank of my vehicle's coolant was deformed and the water was deformed.
Thanks for giving an idea, it was a direct solution rather than giving an idea
