Thank you so much for the info I'm freaking out as I'm still under warranty and have too many mods to undo and take it to the dealership if it were for blown turbos! As I know the turbos are know to fail on 07-10 335i especially when your pushing a lot of boost
Anyways if its just a misfire how could I fix that? Just change spark plug and ignition coils? And if I take it to the dealership to have this fixed do u think they might not fix it under warranty with the mods I have?
And if its a leak in vacuum line or something do u still recommended taking my mods off before taking it to dealership for under warranty work?
Because it going to cost me quite a few bucks to remove Dp and weld the stock muffler back on the car as I'm running no muffler currently
