Currently have my idrive knob disassembled on my table. bought this 2013 328i f30 and it came with an idrive knob that doesnt seem to work at all (prev owner had a spill maybe?). the knob and associated buttons on the part work. wondering what the common reasons are, fixes, other knowledge resources (youtube seems to only have knobs for other years/cars) and how to know what is failing, etc.
