So a while back my idrive would power on at idle but if i press the accelerator pedel it would cut off. I left the car sit bc a transmission malfuntion and now the idrive will not do anything. I have checked all the fuses i have checked the two modules under the glove box. The radio powers on but just to what seems to be a weather band. Im lost i really know nothing about idrive. 2008 bmw 528xi

Because the iDrive cut out when you pressed the accelerator, I'd suggest that the problem is either voltage-related (with the extra RPM contributing to slightly higher voltage) or mechanically intermittent (my stronger suggestion). The slight rotation / movement of the engine and the wiring harnesses associated could explain the issue. If so, the best thing would be to look at all of the relevant wiring harnesses / plugs and remove / inspect / clean (as necessary) and re-seat them, and see if it helps.
