Please what are the symtons of a faulty air flow meter on the 528i? I seem to have a jerky ride between 100 and 120km/h but it normalises above 120km/h which is above the allowed speed limit.
The symptoms I had was reduced low end power (particularly when cold) to the point where I couldn't comfortably pull out into traffic. To test whether or not it was the AFM I simply disconnected the electrical connector. TO me your symtom sounds more like a transmission issue. If you go into sports mode at the critical speed, do the symptoms change at all?
Brett is right. Disconnection of the MAF will send the car into a default or what I call the "dump" mode. (max air and fuel all the time) This will usually cause a rough idle, but you will have plenty of power under full throttle. Did you try what he recommended? Did it work?
