Hi Sven
 Try a 10K 1/4W resistor from gate to source, not the 1K you have....
 I don't know about that small cap across there too, I would think that might screw things up and do the opposite of what the pull-down resistor does!.
 

 Also what s the voltage-feed to your mosfet gate? (reading at the gate with the resistor and the ferrite and everything you have connected to protect the gate)
 

 Maybe your voltage feeding the mosfet is too low, and it will switch but not turn off qucily because of too low of voltage at gate....the mosfets I use have maximum 18V or they blow, and 15V is supposed to be optimum for very quick chop to the turn off....while 9V or 12V "will work" but not most optimum...
