Itse itselleni vastaten. Mahtaisiko vika olla tässä? (Pikku surffauksella löytyi kohtalotoveri

)
"My current C4 had this problem, and the solution for it was a new fan control unit. I don't have the part number to hand, but the unit itself cost around £18 from Citroen.
The symptoms were the fan remaining constantly on, and flattening the battery."
Huolto saa sitten tutkia, oliko vika sama.
