Hi,

I have had this problem since day 1 I bought the car new. It is a STi 07. I have taken it to Subaru Ossie park with this problem. First they said it was normal, then last year before the warranty run out, I took it back to query it, as lots of people who hear it say its not right... They replaced the rear struts saying they were knackered, but the sound continued as again they said it was normal.
Anyway after my 50k service around Christmas, the big $750 major service one, telling them about the same problem, they said there was nothing wrong. But I got the car back and it sounds like a knocking when I take off, sort of like when you put shit fuel in a car and take off slow and in low rpms... But it sounds like its just under the shifter. If I rev it a bit harder and feed the clutch out it goes, same with this clunking noise when I take off in first left or right, that disappears as well.
So I take it to Subaru today for the knocking noise, and the tech picks up on the clunking noise when I take off and says it isn't right, mind you the knocking noise didn't occur!
They took the gearbox off and apart and said that was fine, and that it might be the rear diff. They wanted it for 5 days to take the entire rear diff apart, and I said no unless you can give me a loan car, so needless to say I have the car back atm.
I feel now the car is out of warranty they are trying to sting me for something that was obviously wrong from day 1. But reading other people on the net, they have been told this clunking noise when taking off in first moving left or right is normal!!
Can anyone shed some light on this? or at least advise of a third party mechanic that knows what the hell is going on? I feel Subaru are pissing me around. Or maybe I'm wrong and there is no issue.
