Hummmm... is it on the back left side (wheel) ? My car is due on the 14th to inspect exactly that sort of noise (clank-clank type) which has mystified the dealer some weeks ago when the car went-in for clutch replacement.
I told them: "there is some noise coming from the back"
Dealer: "we did a test-run and think comes from the front"
My reply: "fair enough"
After 2 weeks: "we checked on the front, went again for a test run, you're right, noise comes from the back... maybe a rubber suspension bush in need for replacement..."
My reply: WTF..?
So there we go.
In addition, the clutch seems not OK. It chokes on 1st gear (you just floor it, takes a DEEP breath, then goes... with the previous clutch it was a slam in the face as soon as you applied gas) and sometimes when down-gearing it just takes ages (slips) until engaging... this is particularly noticeable in hill-climbing.
Oh well...
