So,

I got the dreaded 27E4 after a recent brake flush. Though I suspect that fluid had been on the sensor awhile, and the flush finally pushed the sensor to the limit.

I realize you need to just get the OEM part 34302283605 and remove the sensor, and replace the sensor on the car.

HOWEVER, there was a lot of discussion around part 13628657300 which is labeled as a diff pressure sensor, but all the numbers on the sensor match exactly with the sensor on oem part 34302283605.

Well I bought a used diff pressure sensor (13628657300) off a 2014 x2 I believe with about 20k miles, and it seems to be working!

I'm not surprised, I mean its a sensor, it does the same thing no matter where it is in the car, the ECU just determines is range/function based on where its plugged in be it diff, abs, intake etc.

I'll probably replace with a brand new 13628657300 when I muster up to doing that tedious task again. But I think its safe to say its a cross compatible part, saving you about $130!
