Dealership has not been returning my calls and never gave me the codes so I dropped by my dad's place and used his OBDII reader and below are the codes that showed up. Seems to be issues regarding to the throttle sensor/throttle body like you stated prior. Haven't had a chance to look into it yet though as I've been dealing with 80 hour work weeks.

P0120 THROTTLE/PEDAL POSITION SENSOR/SWITCH A CIRCUIT MALFUNCTION
P0221 THROTTLE/PEDAL POSITION SENSOR/SWITCH B CIRCUIT RANGE/PERFORMANCE PROBLEM
P1638 THROTTLE VALVE POSITION CONTROL; THROTTLE STUCK TEMPORARILY

X5 drives like crap but thankfully my girlfriend is being really nice and letting me drive her "daily beater" around...which is an R8 (you don't even want to know what her weekender is). Also both parking spots in the picture are hers so parking like a dick is allowed
