First step in diagnosing the E9X is to get a BMW-capable scan tool and read the codes. A good BMW scan tool will allow you to test the various systems to check their operation. All of those systems are controlled by computer module, most likely the footwell module. A BMW scan tool scans each computer module and finds the trouble codes stored. Once you find the codes, that will help lead you to the faulty device causing the symptom.

A manual transmission can be set to "comfort", "sport", and "track" modes simply by the technique and speed at which you shift it; it doesn't need "modes", modes are for manumatics that try to behave like a real 3-pedal manual transmission. If you can money-shift it, it's a manual transmission. "Yeah, but NO ONE puts an automatic trans shift knob on a manual transmission."
