Cross your fingers the bolt backed out. Otherwise you'll probably need to drop the subframe to extract the broken bolt.
lol. Well said! But I have started working on that.

For anyone else that runs into this problem, here are all the parts you need:

Front bolt with washer 33 17 7 840 535
Rear Bolt 23 00 1 222 891. You need 2 of these.
Washer for rear bolts 07 11 9 931 021. 2 of these too.

I called up my stealership and they never let me down. First they don't have the part in stock, they'll have to order it and it'll take 2 days. Second, they quoted me $15 per rear bolt, and a few dollars for the washers. And they have a minimum 1 hour labor charge at $150/hour to install the bolt. They said they can cut me a deal and only charge for 30 minutes as a minimum. So I'm looking at $100 minimum and 2 day's without a car, best case scenario.

The only other shop in town, hasn't returned my call. And after that, the next closest BMW certified mechanic is the one 100 miles away, who did the maintenance 2 days ago.

Oh this was great help too. But I don't have any tools, but someone else that has this problem might: http://m3forum.net/m3forum/showthread.php?t=345096

Do you have a friend with a jack, stands, and a socket set? If so you can have this done in an hour, including drinking beers... that is if the bolt just backed out.

Actually I do have a friend with that. And that will be the plan. But I actually had to special order the bolts from getbmwparts.com today, so I'm down and out for a few days. No shop around me carries the bolt I need, bmw dealership either. I'm hoping that the bolt just backed out as well. Either way, I can't do anything until the new bolts get here. Order a few extra too. Uh, times like this living on an island sucks.

Make sure you Loctite™ the bolts in when you do them.
I used the red version on mine just to be safe.

Having a friend help is definitely the best solution. Good luck.

Re: Loud "thunk", now running horrible, 2 days after routine maintenance

What could have been possibly damaged by a result of this missing bolt? When I do get it installed, hopefully it's good enough to drive to a shop. But what possible damage should they be looking for? Thanks!

Axles could have rubbed, boots might be torn. Otherwise not much else interferes with the diff.

Ill be scared to change my smg fluid just because its pressurized and a bad change can cause air in the smg lines, and using proper smg fluid is important. Check differential fluid and make sure the fluid is correct I used royal purple in my diff. Also try checking differential bushings. Good Luck man

The differential is clearly well out of it's mounting position, I'd say make sure you check your driveline for damage in front of the diff (driveshaft, guibo, etc)as well as the output shafts.

Check with the shop if they touched the diff mount bolts at all, I don't see why they would have, but you never know. Maybe they found it was loose and then overtorqued it causing it to sheer off after.

Parts arrived, beer got cold, and my buddy had all the right tools! Lined up the differential with a jack, screwed the diff bolt in, and all is well again! It actually runs better than it did when I fight bought it. I think the diff bolt was loose the entire time and finally fell out years later. what I do notice is that there is no longer a small thump when releasing the gas as I decelerate. this used to be a small problem that I never checked in to. But I think this fixed it.

Thanks everyone! if you have a small thump at low speeds while decelerating, double check your diff bolts are torqued to 61 pounds.
