HK Phooey posted some time ago that this happened to him after a trip to the dealer.
He found out at the Texas Mile run when his car wouldn't go past 155mph....spoke to the dealer and sure enough, they plugged his car up - to make sure it had all the updates and wiped his tune and the speed limiter delete, whoops.

3 days ago I took the car to a MB deal for maintenance work and the mid-range power seems to be gone. Unfortunately there is no way to know if the tune was actually wiped off when they reset the odometer.
Has anyone heard of or experienced a tune being wiped out? Maybe its all in my head?
