My 335i Sedan was manufactured in December and delivered in early Februrary. I had the fuel pump replaced after 2000 miles when the car started taking extra long to crank over because the fuel in the line was flowing back while it sat. I also noticed that when I punched it at times the car studdered, as it were. It will take about a week to get the part, but your dealer will likely give you a loaner if you take it to the place you bought it.
Take it in stride. Not a big deal.
Good luck and let us know how it all turns out.
