i think i have a similar problem, got 71k miles and on cold start up there is a fairly loud rattle with an underlying ticking at idle. When the engine has warmed up the rattle almost disappears but the ticking remains. Under acceleration both seem to disappear. Ive had both turbos replaced so its not (or shouldnt be) those, any ideas? dont mean to hijack the thread but wanted to be notified of any replies
