dug into it deeper. it appears those bolts are originally aluminum from the factory. they require an initial torque, then an angle torque. they also have a special torx tool called out (i think its just an odd length, due access clearance). stripping or snapping seems plausible. based on posts online, some of the bolts snap themselves just from the car running. however, it also looks like they've recalled those bolts and replacements are now steel so the whole point may be moot.
repair procedure (which seems to precede the change of bolts to steel)

but, keep in mind I have very little knowledge of new engine codes and if any of this even applies to your N51/2/3/4/5/6/7/8/9 engine

Thanks for the link! I hadn't seen that document yet. What I find interesting is that they don't include the E91 in the actual recall (only extended warranty), even though it lands right in the middle of all the affected models and was produced throughout the affected time range:
My car has the N52K with a build date of 4/2010, so unless they had some special N52K for the wagons it should be the exact same thing as any other e9x with that engine. Maybe since there were a lot fewer produced? Who knows...

LOL. Also at "Ultimate Customer Experience" I'm sure people who come in because bolts are breaking and their car runs like garbage are having a great experience.
@m42b32 the F11 is also excluded. It my be a clerical thing, like the tourings are assumed as part of the e90 cars.

BMW just denies the existence of the wagon in their lineup. Much like the holocaust, BMW doesn't want anyone to know they have anything to do with this segment.

The car has been dropped off at BMW Milwaukee North last night. I just got a call back after an initial diagnostic check and the exhaust vanos actuator is not functioning properly. They can't verify the bolts are the problem and confirm it is a warrantied repair until they inspect the actuator visually, so I've given them the go ahead to pull the valve cover. If you aren't familiar with the newer engines, the valve cover is a much more difficult process than previous generations of engines, so they estimate about 7 hours to R&R. If this issue is indeed broken or loose actuator bolts, everything is covered. If not, I'm on the hook for a pretty hefty bill. I've never been so hopeful something specific on my car is broken...

Did you get $50 worth of stale cookies and room temp coffee when you dropped the car off?

I had a similar feeling when I dropped my 335i off to find out if the turbos would be covered under the extended warranty. I remember the advisor was very explicit that I would be on the hook for the diag if it was not covered. It wasn't 7hrs of diag but I feel your pain.

It feels like such a ridiculous policy but I don't know how they would do it any other way... I've been checking my phone like a psycho all morning.

Yea, I used to deal with this with insurance claims to. The insurance company would tell a customer the same thing and a customer was never happy but at the end of it neither myself, our insurance company or any customer was able to come up with a better solution. It just sucks.

Thanks to some broken/loose bolts, it's getting fixed for $free.99!

Got the car back Saturday morning! I didn't owe a dime which was extra awesome (surprise and delight!). Final diagnosis was loose bolts on the exhaust vanos actuator, thankfully nothing sheared so they didn't have to pull the oil pan. Intake actuator didn't have any issues so updated bolts were installed instead of replacing the unit. Work performed:
- New exhaust vanos actuator
- 4 intake vanos actuator bolts
- Valve cover gasket (Mine was leaking, so this is a nice bonus)
