2002 bmw x5 3.0 no throttle response

I have a feeling there is an 01/02 part mismatch. Notice the part for 01 and 02 have completely different pin out for most of the connections on the throttle body.

The COLOR of the wires are the same by function.

Pin 5&3 are the motor on a 2002.

You said the DME was replaced and also the throttle body. Check the wires by color and by pinout. Also there is confusion of which is the throttle motor v throttle sensor on the wire diagram I'm not sure you have the right pins figure out. I would try to match the color and purpose to determine correct pin.

I think your right...

I bought the dme ,ews , key and ignition on eBay all together. the description is for a 2002 BMW X5 .

Can put an 2001 dme BMW in and keep the same ews and key? Or do they have to be changed together?

Those three have to go together that's why they are sold as a matched set.

It feels like you have a 2001 throttle body on a 2002 car and look how the pinout is radically changed.

I think you can pull the pins out of the connector and rewire the throttle body connector if I'm correct but you can check the voltage on the pin 3&5 vs 4&6 before to make sure. Fortunately sending motor signal to the sensor will not likely cause a problem but I would measure the Ω across the two sensor wipers to check them before trying to run the engine.

I think you are close. Find the right wires by color and function. Trace from the throttle body to the DME
