Installed 2 VW MAFs from Autohaus, Arizona today on my 2000 M5, per all the threads on this subject. Fit fine, only missing the locking tabs, easy fix. The engine fired right up, idled smoothly and pulled strong on full throttle acceleration runs up to 4500 rpm;, best I could risk on neighborhood streets!. Will report back if problems develop or mileage suffers.
The part number on the box was different than on the sensor and both different from anything I´ve read on the subject. No Bosch or other manufacturer name. But, works fine and price is right.
