Correct part # for rear brake pad sensor?

[BigRussia]

So I'm dealing with really annoying brake pad sensor issues and errors illustrated here and along with that I'm also dealing with trying to find the correct replacement rear brake pad wear sensor for my 2009 135i Coupe E82. I bought one from FCP Euro that they said fit my car and with the correct part number from RealOEM (34356789445) but it doesn't fit, the fitting that clips into the pad is different. But no matter where I look online that seems to be the correct part number for a 135i's rear pad sensor. I have a pic attached of my factory sensor and the one I was sent, as you can see the clips are different. Whats the true part number for the rear pad sensor and where can I find it?

Ok guys I think i finally found a replacement rear brake sensor with the correct matching sensor fitting/clip as the one of my car. Strangely enough it has the same 34356789445 part number as all the other ones with the other fitting/clip that didnt fit my pads. This is really strange and I cant believe this topic has never came up!

Here's the link to the part with close ups of the fitting.
