I had my '08 E93 in for a brake fluid change and also to them the brake pedal was hard to push after the car was parked for 2 hours. The service manager told me this was normal. I showed him a service bulletin for the '07 3 series with the same problem and again I was told my problem was normal for my car. I called BMW NA and they were no help. I will be meeting with the factory rep at the end of the month.
