BMW started with the "bleed procedure" which only fixed the car for that drive cycle... Then went to complete cylinder heads with an updated design/redesigned oil passages etc. which fixed the car. Now to save money on the cost of heads they started just changing the HVA's for the exhaust bank. This does fix most, but some come back ticking and end up with the complete head replacement.
Keep in mind these "fix it" decisions aren't decides by the tech or the dealership, but the BMWNA mothership. We need to get approval for these repairs before doing them or the warranty claim will not be paid.

My car's actually in shop for this problem, getting the HVAs replaced right now.
But I sort of hoped that I would get the cylinder head replacement 'cause I heard reports that getting the newly designed cylinder head gives better performance feel like a little more horsepower or so I hear. Oh well...

Extra HP felt with the new head are mainly due to all the adaptations being cleared as part of the job. There is a chance the tech will do that with the HVA's as well. (I do, but not all techs do)

So I finally got around to taking my 330i in for this issue, and today I got a call from my SA that BMWNA does not want to approve the repairs, despite the SIB. I've contacted BMWNA, and they are going to contact the dealer and try to figure it out. What should I do if they come back and still say no? My car clearly has the clatter, sometimes it sounds like a diesel, they are trying to tell me that this is within their spec, and I disagree.

The dealer will get the updated part number to order from the teileclearing case they need to get replacement authorization... so you don't really need to track it down yourself.

The dealer I go to is pretty incompetent. For the HVA replacement, I had to print out the SIB someone thankfully posted here. Before that, they had no idea what I was talking about. I'm afraid they might just say no more work will enhance the problem and then I won't have any thing to show to their faces.
