hi guys, i rarely give my 328i some throttle and today i did, and when i was braking a BIT more than usual my pedal vibrated 2 different times and after the second my car is kind of limping? when switching gears (AT). ? i tried resetting the "maps" that come factory with the gas pedal thing of holding for 25 secs while engine is off and not much of a difference..and i have done the reset before and worked like a charm but never had the vibration when braking harder than what i did today
No warranty, and is it something that will go away? something i should be worried about?
