Warning: Water in diesel fuel

Hello, first of all, good form, I have been using this car for about 10 years. Lately, I have been receiving a warning saying there is too much water in the diesel. Because of this warning, the car sometimes doesn't start after waiting 5 minutes. Sometimes it starts when I drain the diesel from the pump, sometimes it doesn't start at all. I used to buy diesel from Opet and after these problems, I switched to PO and it is still continuing. Because of this problem, I changed the filter twice. They found an excuse saying the first pump was faulty and I am still having the same problem with my second filter. I always take the car on long trips out of town and I am afraid of leaving it outside. If the problem is not the diesel pump, where is it?

Hello sir. I'm a 307 1.6 HDI owner. I experienced a similar problem. Maybe this will help you. My car's battery was very weak, so I bought a Volt battery because it was affordable. The battery was installed, and a month later, these ridiculous warning lights started flashing all over the car. I had the car serviced around the time I changed the battery. The first error message I received was a warning about water in the fuel filter. I opened the filter's water drain plug and drained a lot of fuel. I had the errors in the ECU cleared. The next day, the problem occurred again. I took it to the mechanic, who said the circuit on the filter was faulty, and we tried another car. The same thing happened. Changing the filter, etc., didn't fix the problem, and other problems started to occur over the course of a week. Now, the real problem started after that. While investigating the problem with the mechanic, we noticed that the battery was leaking acid. The cables coming from the ECU were running under the battery, and the acid from the battery had completely flowed into the cable channel coming from the ECU, melting almost all the cables, causing a short circuit. That's why I was getting ridiculous problems. Once I isolated the cables, all the problems went away immediately :) I experienced a lot during this process. First, drain the fuel filter through the water drain plug. If that doesn't solve the problem, you can try replacing the fuel filter and the circuit board or whatever it's called. When changing the filter, be careful not to let fuel drain from the old filter into the new one. People are too lazy to pump with a handheld or pump for two minutes, so they drain fuel from the old filter into the new one. I recommend checking the fuses, battery, and electrical components. In the unlikely event that the tank cap isn't leaking water and that there's no water accumulation in the tank, this is a last resort.

Hello, I have the same problem, we can't figure it out. Did you solve the problem?

Hello, did you find a solution?
