BMW 6 Series - Tech Talk E24,E63,E64,F12,F13
Can anyone help at all.
I have a UK spec 630i Auto (2006). Its all good apart from a couple of things that annoy me.
I am mechanically adept. (Build Motorcycles)
When i start it up from cold, sometimes its very "Tappy" at the top end.
Im guessing its oil flow around the cams as when...
