Yes I believe mine was in the range, manufacture date 3-2005. I am planning on doing a leak down test and listen for air escaping to see what gives. I have removed both the intake and exhaust camshafts. I'm determined to get this thing running smoothly again. I am only the second owner and the first took good care of it. It now has 140K miles on it.

June 04 to Feb 05 according to the service bulletin.

Somebody on xo just recently posted they were able to get the Valvetronic adjusted but that if the problem returned the eccentric shafts would need to be replaced.

Update, I did a leak down test and all cylinders are good with no loss. Now my thinking is it is either levers, cam, or eccentric shaft. I was thinking of purchasing a used head complete with gears etc and using those parts in hopes of correcting this issue.
Has anyone had to do this? New parts are too expensive for me so I am willing to chance it on hopefully a lower mileage used part.
