i have the same issue with my 04 530. except i have a manual and it happens at 2200 rpm only in second gear. i have a warranty through the small dealership i got the car from. im going to call them in the morning and see what they say. i will mention that i know about the issue with the mechatronics unit.
i will also contact my local bmw dealer and ask if they have had this issue come in. theyre not gonna like a 20 year old kid coming in and giving them **** about this, so im already going to be fighting an uphill battle.
