Yep. I think I get this on my 2004 E46. When you first get in the car, wether its morning day or night, and you don't warm it up for at least 5 minutes, when you shift into Drive (i have an auto), give it some gas, the engine will begin to revv, but the car won't move. In about 3-5 seconds it suddenly grips though, and starts moving. I don't know what it is. I'll have the dealer check it out when I service it. It's a pretty common problem, but only on some cars for some reason. I didn't have it on my x5, and my family's 330ci doesn't have that either...Go figure.
Another common problem is the Harman Kardon gets distorted at higher volumes on he passengers side. Tres bizarre.
