The fan turns on automatically and does not consume gas.

Hello, I have a 2011 1.6-liter gasoline 508 with no LPG. When the car is driving normally, the fan automatically turns on and doesn't use gas. The engine is also running a bit strangely, but the temperature gauge is normal. Sometimes I stop the car and start it, and sometimes I disconnect and reconnect the battery terminal, and the problem is solved, and the car runs normally. Has anyone experienced this or know the cause? I'd like your help.

Hello sir, there are probably two sources of the problem. 1- ignition system coil and spark plugs. 2- multiple eccentric oiler (sourced from electrovalves). Of course, first of all, it needs to be checked with a fault detection device.
