Air Flow Meter

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.

Welcome to the Werkz.

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?


Riding in style

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?
