Dont rely on the bulletin for the date range. Its not accurate. The problem is a much larger range. Any of the engines that have valvetronic can have lever issues including the 6 cylinder in the e90 for example. Dont just do the levers either, replace the eccentric shaft of the bank thats misfiring. You dont want to go in there twice. As I have stated in other posts, there is testing that can be done to see if the issue is valvetronic related.
