- 0928400527 OR 0928400314 – is the REPROGRAMMING really NECESSARY?
MUCH CONFUSION ABOUT THE MAF FOR BMW DIESEL VEHICLES
Since there seems to be a lot of confusion around the Bosch hot film mass meter 0 928 400 527 (0928400468) or 0 928 400 314, I would like to explain the issue that driver of BMW E46 are faced with.
BMW drivers today can only buy the part number 0.928.400.527.
Item 0928400314 and 0928400468 are no longer available.
Clients who needed to exchange the MAF have been told, that the ECU needs to be reprogrammed with the new MAF. But to our experience recognizes the ECU the new MAF 0928400527 even without reprogramming. Usually the ECU “recognizes” the new part after 50 to 100 km at the latest.
On the right side you find the exact list in which Diesel BMWs the air flow meter was changed.
The BMW numbers are: 13712247002, 13627787076, 13622247074
Some visitors reported that they have installed the 314 in their BMWs, although according to the list they are supposed to have the new 527. This list has thus been passed on to all BMW workshops, but there is a suspicion that it is facelift-dependent for some vehicles.
The best thing to do is to always check what is originally installed.
