    Hi all im new on here and i was wondering if anyone with the knowledge can help me out please
    My water pump died on me so i got that replaced but ever since then I have a issue with the radiator fan's coming on after 10 seconds even on acold start and stay on throught my journey, i did a diagnostic test and it came up as Error P0480 which is a fan module i have changed fan's, temperature sensor's, fan relay in the fuse box still nothing,
    Does anyone know what could be the problem
    My car is a mk5 gti dsg

    It does sound like a faulty temp sensor... Have you air-conditioning?

    Have you replaced the fan module at all?
    And do both fans work, sure they have brush issues from a conversation years ago, one stalls the other works overtime.
    Check they both turn but carefully and not with fingers.

    If the a/c is on, it usually brings on a fan.
