I deminded some answer thanks for encouragment guys. What they said. The dirt is got between a filter and a sensor. They not think is wise to clean it, they still stick to the story it will damage a sensor itself. I managed to get a price down "only" 475.00 to get a new sensor now.
Problem is what ever phone number I call it is directed to the main Canon Australia Service. I can not talk to somebody higher than a  technical support and complain about a handling of this matter.

I love my canon, next time I will send it to america....lol

seeya  and thanks again. Tunde
