On another thread killcrap states:
"all n62b44 and n62b48 variations have this problem, the production dates dont mean anything. it is a design flaw. rough running. i have worked on 2 or 3 cars where it has been through 3 sets of levers and shafts. early e65 vehicles had rough running at engine operating temperature in warm climates also, e53 vehicles have the majority of the problems in cold weather."

and

"they wore out every 30k miles. and each time it has been goodwill repair, that car has also been through 2 intake manifold, 1st time is was siezed and 2 time it was sloppy."

Is this still really the case now? Did BMW come with a better solution?
Is this what you guys are doing every 30k miles?
