Car is a 2009 335xi with 46K and still under warranty though a little nervous with the numerous mods that have been done, also CPO till 100K.... Cobb, CAI, FMIC, BOV just to name a few.

Do I set back to stock, Cobb, and play dumb or fess up and see what they will do. I'd like all plugs and coils replaced and willing to play if that's not the issue. I've seen through the forum that they should be replaced every 25K though the service person told me every 100K.
