2008 X3 Ambient Temp Sensor location

[Bmwdan750]

Hello I'm new here but I got a 08 X3 and I needs a ambient temperature sensor, I bought the sensor and can not find the old one. It looks to be ripped out. I found a two wires with nothing attached and another group of wires with 3 wires dangling. I connected it to the two wires and it did not work. I'm looking for a wiring diagram for the sensor.

Welcome to the forum. I started your own thread on this issue. Hopefully someone here will be able to assist you.

While i am not familiar with the vehicle, I am looking at the WDS currently and find the image below. B21a shows to be the outside temp sensor on your vehicle. H2a shows to be 'Left horn'.

H2a, X132, B21a, X770

I'm working a 2008 BMW X3 and got the code p0073. I purchased the ambient temp sensor but I can not find the old one or wiring. Looks as if the previous owner hit a curb and it was damaged underneath. I found a two groups of wires with no harness attached. one has 2 wires one brown and the other green and black and another group of wires with 3 wires Hanging out yellow green, brown black and green brown. I also see someone installed aftermarket HID's and messed with wires in there. I'm looking for a wiring diagram for the sensor to figure out we're to find the wires.
