Lucky the 07 Cooper is barely still under warrenty.

The car lost virtually all power several days ago, a logo came on that (I found out later) meant not to drive it anymore. Then about 10 minutes later the power came back, and after several engine starts/stops the lights went out.

Went to the dealer today to have the codes read and they replace the valvetronic, or whatever, servo motor.

Anybody else have this problem?

Thanks.
