Problems Arise
 Just before the 4000 mile mark, I noticed oil drips on my garage floor. I made a service appointment, and the next day, after being out overnite in a snowstorm, it had a hard time starting, and then driving at speed, the "engine malfunction - reduce power" warning lite came on. We were near a BMW dealer so stopped there - they diagnosed the engine warning as a fuel pressure sensor failure; and they could not precisely diagnose the oil leak, saying that the transmission will have to be removed to see where it is leaking. The work  requires sending pictures and documentation to Germany for repair authorization, so i can expect to be without the car for up to a week. Unacceptable reliability.
