My rear camera works fine sometimes, other times ...not so much. An indy repair shop said wiring connector appeared to have corrosion on it, but, they didn't "fix" it. BMW dealer says they want $3,000 and they'll install new camera, connector and ECU; (which seems excessive). I believe the camera is fine and that it's either the wiring connector and/or the ECU.

I've looked on RealOEM and can't tell where the ECU is located. Does anyone know? I can then inspect wiring harness/connector and repair/replace as needed.

Thanks in advance,

Jay
