Low tire pressure
So I decided to drive my car to work today, been sitting in garage for last 5 days and pull out driveway and tire pressure light say 20psi. My question is with these run flat tires if I have a nail in it can it get repaired if its not in the sidewall.

Normally if its in the outer tread bars the tire places will also not fix those so you end up buying a new tire. You can always try plugging a nail hole in those outer tread bars but runflats are tough to plug with the kits that you buy at the auto stores.
Take it to a reputable tire store and have the tire inspected. It might just be you have not checked your tire pressures in a long time. They do lose some air over time.
Good luck with it.

I haven't had my car all that long and I ran into the same thing. The dealer would not repair and some tire shops say yes and some say no. Find a good tire shop you trust right now that will torque your wheels properly. Tire rack website says the Michelin run flats you have can be repaired once if it's not near the edge of the tire.

Yes, but make sure you plug, and patch it, not just a plug.

One repair allowed by Michelin and the tire will maintain it's speed rating: http://www.tirerack.com/tires/tirete...jsp?techid=225
Proper repair, patch and plug: http://www.tirerack.com/tires/tirete....jsp?techid=77
If you have a hole, find a shop which is experienced in dealing with wide low profile tires. Getting the tire dismounted and remounted runs risk of damaging the rim if done without the proper equipment.

Any repair attempted without removing the tire from the wheel is improper. Without inspecting the inside of the tire for hidden damage comes the risk of returning a weakened tire to service. Punctures in the tread area that looked repairable have revealed upon further investigation that the object that punctured the tire had been long enough to cut the tire's sidewall from the inside. Without dismounting the tire, the hidden damage would have been missed.
Simply plugging a tire from the outside without removing the tire from the wheel is improper. (If a tire is punctured while off-roading far away from civilization and a spare tire isn't available, a plug may serve as a temporary low speed solution that must be replaced with a proper repair as soon as possible upon returning to the road.)
Additionally, any repair that doesn't completely fill the path the object took through the tire is incomplete. While a patch on the inside of the tire reseals the innerliner, it does not fill the path of the puncture. This will allow moisture to reach the steel belts and/or the casing cords causing them to rust or deteriorate.

That is incorrect. A plug and patch repair is the correct way to repair a tire. Mythird1 explains it very well.
Of course, it may not need repairing. It may just need air. Tires will lose air pressure over time, especially in colder temps.
