Bought an e92 330i 2008 (with iDrive, BT, Nav, and no USB), and the BT does not work.
Already tried many things with no success (different phones, disconnect the mulf, the battery...).

Anyways, today I visited the dealer for diagnostics. They said I need a new MULF2 and the part number I need is 84109226711. The price for a new MULF2 is ....wait for it....wait for it....$1318.

So, I would like to buy a second hand on ebay. However, when I look at my trunk, the current MULF2 part number I have is 84109163348.

here it is:









Are these two parts exchangeable ?

When I look at BMWFANS, I see that 84109226711 is Bilaterally exchangeable with 84109224673 and 84109163348 is Bilaterally exchangeable with 84109149656 but the one I have is not exchangeable with what BMW said I need.

Is there anyone here that share some light on this?? I really don't want to spend $150-$200 on a unit that does not fit my car.

Thanks!

I got this answer from someone. I don't know if that is a complete list or if it's accurate. Can you help verify?

"84109163348 -> 84109147516 -> 84109162982 -> 84109178 862 -> 84109195246 -> 84109200821 -> 84109204545 -> 84109226711
Any of those will work."

Update -


I followed part number history and discovered that the following parts are all bilaterally exchangeable :
84106983330
84109116725
84109123290
84109128722
84109132539
84109149656
84109163348
84109147516
84109162982
84109178862
84109181378
84109195246
84109200821
84109200821
84109204545
84109215184
84109221029
84109224673
84109226711

Than I bought one of the above mentioned parts (used from e-bay) and installed it today. Everything works like a charm! No coding is needed for me. Just plug and play :-)
I'm so happy. Finally I can drive the car without feeling embarrassed that I'm using earphones instead of Bluetooth…
