No service update yet but I had to go back because the 328 bugged out on me! There was a loud buzzing noise from the rear panel that would not shut off. So long story short, I now have an E90 335i. This thing has so much torque!
Hahaha. Sorry, but the 335 has nothing on an M3. Having said that it is a great little car and gives me hope for the future of BMW turbos.
