Nope.. Its quite common for the oil to overflow from the white reservoir, but i dont exactly know under what circumstances.
As for the the wo wo wo sound, im not sure what exactly are u referring to.. Mb a more clear description can help.
Sien. Discussion kolos.. Btw u can make as FB instead... Get Polo with GTi bodykit also.. hehe..

Oh i get what u meant.. Thats the orifice valve pressure release sound.. It sounds like Darth Vader breathing through his mask, or if u dont know star wars, its like water gushing through a small pipe.. Basically what that sound is when u turn ur steering wheel the power steering motor pumps up the oil pressure as u turn the steering, but once u set it straight the pressure will have to be relieved, which causes the sound.. The sound is in all the cars, but mb u were not that alert when ur car was still new.. 

is the sound is wooo wooo woo.. is normal when steer steering.. if when got ngikk ngikkk sound when steer... then got problem liao... another info want share to u all.
