im having the same problem
i was wondering if you sorted the problem with your power steering?
im having the same problem with the same car (im in nz too)
i cont have any manual from the dealer,and everything else i have isnt in english!
local mechanic tells me he will need my car for a few days to try and find out what the problem is.bugger that,im not paying him hundreds of $$$ for him to pull my car apart and still not know what is wrong!
i was hoping you might be able to help,if you have fixed yours
ps, this happened when i first got the car - power steering went very hard and the eps light came on but then it seemed to fix itself later the same day.this time it has stayed like this all weekend,and it sux:mad lol
thanks
