OK have some kinda cool news here. I will try to write it up later to try and trouble shoot.

Here goes.

If the beep is from the rear it IS one of the rear sensors.

I took one of the good front (only the two center sensors will work, the side sensors have a different connector/ it has a 90 degree bend)

So I took one of the front sensors and took one of the back sensors and swapped them out. Same result, beep from the back. I then moved to the other three sensor one by one until I found the bad one. Which was far right passenger side.

I had to take each sensor and move it to the front as i tested them. When I took the bad sensor and plugged it to the front, the beep came from the front.

And Bingo was his name ' O

There ya go,

Takes a bit of doing but it can be done. If you decide to try and take them out from the outside, be very careful. They are a biatch to get out without breaking. Much better to get them from the inside.

One other thing. I have found out they use the same sensors on the 5 series and the 7 series.

Not sure on year swapping or what year is good from what to what... still working on that.


Like I said, I will try to take pics and do a write-up if anyone thinks it is worth it.
