Can you guys help me out on this? It's driving me nuts and the stealer doesn't know either.. just keeps throwing random guesses that could make him some more cash...
I have a knocking-like sound from a cold engine start, it lasts for 2 to 5 minutes then it gradualy dissapears (the knock become less often until they are no more).
This is a link so you can hear it : http://1drv.ms/1irKgwB
(clutch depressed at around 20s mark).
Here is all I could document about it:
Clutch on/off : with the clutch on, the noise is still there, but much attenuated.
It's mostly noticeable around idle speed.
Can't seem to relate it to outside temperature/humidity or other factors (it goes during the winter as well as during the summer).
With a warm engine start, there is no such sound.
Sometimes, even with a cold engine (outside overnight), the engine starts fine and there is no such noise.
Clutch, clutch plate and flywheel are new (2000km). The noise was there before and persists after the change.
