Just wanted to add my experience to the thread. I have an 06 330i and have been experiencing the dreaded valve tap for the last 3 or 4 months. Monterey BMW started by bleeding the valve lifters. No dice. Brought it back and they opened a PUMA case, then were advised to replace the exhaust side valve lifters. The tapping was back two days after I got it back and it starts and idles rougher than before. Now I'm bringing it back again and they want to try replacing the intake side lifters before replacing the entire head assembly. This has been an enormous PIA and I hope they can get this fixed!! I think I read somwhere on here that someone still had the issue after a head replacement so I'm trying not to be too optimistic.
