click-click-click sound when engine is cold
Once I drive for about 2 miles, I do not hear a thing anymore at ALL. Took it to the dealer, of course the only way I can replicate this is to leave the engine cold for 8-9 hours, dealer said, 'yeah it's normal' The sound is very low and not as loud as you would get say if experiencing a piston slap... So do you guys have the same experience? 2007, 3.0.

This is a known issue with this engine:
Xoutpost.com - View Single Post - How does your engine sound.... Xoutpost.com - View Single Post - marvel mystery oil The head or rockers need to be replaced if the bleed procedure doesn't fix the issue. Check with X5 Meister if he can pull up the TSB for you to take to the dealer.

Thanks guys! X5 Meister's inbox is full, tried to PM him. If anyone has or can point me to the TSB will very much appreciate it.
Although this sound happens for a short while and infrequently, I'd rather nip it now that it's under warranty.

I have a first batch (custom ordered mine) 08 3.0si and have the same issue. Thought it was low oil level but guess it might not be the case. I'd also appreciate the TSM info if someone could refer it. Thanks so much!

I've replaced so many of the N52 heads for the "lifter tap" that I can do it in one day after lunch. I do the bleed down procedure then let the car sit overnight. If it does it in the morning I get PuMA approval to replace the head and order parts. The new head design has redesigned oil passages and some additional oil drainback valves etc. Have not had any problems after head replacement whatsoever.
By the way, the "bleeding procedure" in the TSB is just holding it at 3500-4000 rpms for 5 to 15 minutes to pump the HVA units full of oil, which almost always quiets it up at that time. But the same results come from a 10 minute drive on the highway... so don't put too much stock in it.
