    Which year/engine?

    Check the intake manifold flap has not seized as they sometimes the older ones have plastic teeth that break internally.

    I would disconnect the fan unit, replace fuse, turn ignition on, clear all faults, then see if the intake flap is showing a fault or fuse has blow again.

    I believe that the fuse that supplies the engine fan is the same one that supplies the intake manifold flap. If the intake manifold flap is closed, the engine should not start (it cut's off the air from the manifold). It might be useful to first of all disconnect the fan, replace the fuse and see if it starts. If the fuse blows again, then the fault lies with the manifold flap motor. If it starts, then the fan needs attention/replacement. Good luck.

    Yeah big connector behind the fan unit, cant miss it tbh.

    You'll need to remove the imf & open it up to check what its like inside, but try removing the flap & moving the flap by hand 1st, if it doesnt move then its seized.

    Open bonnet, look directly down betwee front of engine & the fan unit & you will see the 2 fans & iirc slightly on the left at bottom of the fans there's a chunky connector there to unplug.

    The flap is fitted to the front of the engine, with the intake big fat pipe coming up towards it from bottom.

    TBH if you're not that minded, then maybe ask someone else to do it as you could cause more issues, no offense.

    Ok thanks for the advice, i know where the flap is now.. Do i have to remove the whole part to see if its seized or is there a way i can check while its still on the car?

    If you can get a finger up inside to move the flap, then yeah try that.

    Too dark :P, tbh with a torch during dark its allot easier to see where the bits are, as daylight can distort things in engine bay

    It looks like that, but you have to check part number 1st, but condemn a system before ordering of course.

    Right boys, tested it with the fan off and still didnt start, so i took the manifold flap off, and the value inside is so hard too move, could this be the reason its blowing the fuse?
    I'm just about to order new part.. do you all believe this is the reason the car wont start?
