Hpfp, one coil, a lambda o2 and the passenger side window guide. This in 40xxx miles, about 12k tuned. All covered under warranty. The n54 is a tremendous engine, just awesome. The car goes in for scheduled maintenance tomorrow but its running great and was in for the o2 at 36xxx miles so i think all is well.
