Hi
Our 2003 Turbo has developed a knocking noise at idle. It's ok when cold, but when up to temperature, there is a distinct knock knock knock sound which seems to cycle. It will knock say 10 times then go quiet for a few seconds then knock again. Doesn't matter if clutch is depressed or not, and disappears with revs.
Any thoughts on what it could be? Sounds to deep annoys to be a rapper I think.
Thanks
